[PHP] First time PHP user question
Hello List. I have been playing around with PHP, running a few tutorials and I came across an error message I could not resolve. The tutorial is Generating One Time URL's by Oreilly: http://www.oreillynet.com/pub/a/php/2002/12/05/one_time_URLs.html Basically the PHP code is supposed to read from a text file and write to a text file and serve a text file all located in the "tmp" directory of the server. However, I receive the error that the referenced files in the PHP code could not be found: "Warning: readfile(/tmp/secret_file.txt) [function.readfile]: failed to open stream: No such file or directory in/home/mysite/myfolder/ get_file.php on line 67" Line 66 and 67 look like this: $secretfile = "/tmp/secret_file.txt"; readfile($secretfile); However, in the tmp folder, I have created a simple text file called "secret_file.txt" so I know it exists and it has the permissions set to 644, so it should be readable. Can someone point out to me what I am doing wrong? Thanks, --Rick -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Re: First time PHP user question
Thanks Ashley & Nathan.
As it turns out, there is more than one "tmp" folder... and I was
looking in the wrong one. When I SSH'd in the correct one, I created
the missing file and it began to work properly.
Thanks for chiming in.

try permissions of 777 and see if the error disappears; odds are v
high
that the httpd user php is running under doesn't have group or owner
permissions for /tmp & that secret file.
regards
That shouldn't fix it. 644 permissions allow the owner, group users
and anybody else to read file. Have you tried is_file("/tmp/
secret_file.txt"); to see if it actually exists? Also, don't forget
that Linux is case sensitive when it comes to filenames, so
secret_file.txt is completely different from Secret_File.txt, and in-
fact you can validly have both in the same directory.
Thanks,
Ash

[PHP] Formatting Decimals
Hello List. Probably an easy question, but I am not able to format a number to round up from 3 numbers after the decimal to just 2. My code looks like this: $newprice = "$".number_format($old_price, 2, ".", ","); and this returns "$0.109" when I am looking for "$0.11". I tried: $newprice = "$".round(number_format($old_price, 2, ".", ","),2); But no luck. Any help is appreciated. Thanks, --Rick -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Formatting Decimals
I have been asked to further modify the value to the nearest half cent.
So if the 3rd decimal spot ends in 1 or 2, it gets rounded down to 0
If it ends in 3, 4, 5, 6 it gets rounded to 5. And if it 7, 8 or 9 it
gets rounded up to full cents.
Can this be done fairly easily? Not knowing PHP well, I am not aware
of the logic to configure this accordingly.
Thanks,

Re: [PHP] Formatting Decimals Further Help
Hello List.
In an earlier post, I received help with a custom function to round
decimals off (the custom function provided by Adam Richardson is below).
However in my MySQL db, when I have values with only 1 decimal point,
I need the value PHP returns to display as 2. For example, 3.8 needs
to display as 3.80.
My line of code that calls the custom function looks like this:
$my_price = round_to_half_cent(number_format($my_price, 3, '.', ','));
When the value of $my_price is 3.81, it returns 3.81. However, when
the value of $my_price is 3.8 that is what it returns.
How can I force the formatting of my_price to always contain either 2
or 3 decimal points (3 if the original number contains 3 or more
decimal points to begin with)
Thanks,
--Rick

However that's not what Rick is asking for. He needs a function
that rounds
to the half penny with a bias to rounding up (greedy bosses):
Actual Rounded Diff
.011 .010-.001
.012 .010-.002
.013 .015+.002
.014 .015+.001
.015 .015 .000
.016 .015-.001
.017 .020+.003
.018 .020+.002
.019 .020+.001
.020 .020 .000
Bias +.005
This could easily be implemented by getting the 3rd decimal and
using it in
a switch() statement.
An unbiased system could look like:
Actual Rounded Diff
.011 .010-.001
.012 .010-.002
.013 .015+.002
.014 .015+.001
.015 .015 .000
.016 .015-.001
.017 .020-.002
.018 .020+.002
.019 .020+.001
.020 .020 .000
Bias.000
The only difference is the case where the third decimal is 7.

What you have is a display problem so use one of the many PHP functions to display numbers and don't worry about how it's stored. Hi Ted. This is exactly what I am trying to do, some of the values in the DB are going to have 3 decimals, some 2 and some 1. On my page I pull the value from the db with: $my_price = $row['my_price']; This returns 3.80... even though my db has it as 3.8. No problem. But once I run the variable $my_price through the following line of code, it is truncating the 0: $my_price = round_to_half_cent(number_format($my_price, 3, '.', ',')); Again, the above call to the custom function works fine for 2 and 3 decimal points just not 1 decimal point. Because I call this function over many pages, I would prefer if possible to fix it at the custom function level rather than recode each page. But I will do whatever is necessary. I afraid with my current understanding of PHP I am not able to successfully modify the custom function to tack on a 0 when the decimal place is empty.

your doing the number format before the rounding.. here's a version of

function round_to_half_cent( $value )
{
$value *= 100;
if( $value == (int)$value || $value < ((int)$value)+0.3 ) {
return number_format( (int)$value/100 , 2);

}
return number_format( 0.005+(int)$value/100 , 3);
}
echo round_to_half_cent( 12.1 ); // 12.10
echo round_to_half_cent( 12.103 ); // 12.105
echo round_to_half_cent( 12.107 ); // 12.11

[PHP] PHP Syntax Help - Check?
Hello all.

Re: [PHP] PHP Syntax Help - Check?
OK... external function... that would explain why I could not locate it.
Let me get right to the problem I am having with this code as someone
may be able to help directly.
I have a link on a page that opens a contact form. The link is
mypage.php?my_id=5
So on mypage.php, I capture this value with:
$my_id=$_GET['my_id'];
I understand this much. But when the end user submits this contact
form they do so to formcheck.php and if formcheck.php sees a required
field is blank, it throws it back to mypage.php with an alert. BUT, I
lose the value of the variable $my_id. SO, I created a hidden field
on mypate.php with value="" and on
formcheck.php, I added $my_id = $_Post['my_id'];
However, when formcheck.php returns me to mypage.php, $my_id is still
blank.
Very frustrating.
Any help determining what I am doing wrong is greatly appreciated.
Thanks.

In the above, check is a function. It is being called with parameter
'element8'.
This is true. But perhaps more importantly, check() is not a native
PHP
function. Thus it comes from some other library or group of external
functions.

Re: [PHP] PHP Syntax Help - Check?
Hmm. OK with the help below, I am closer.
The other fields on the page are getting passed via form fields that
look like this:
input type="text" value=""
name="form[element9]" size="40" maxlength="255"
so I added:
input type="text" value=""
name="form[my_id]" size="40" maxlength="255"
and formcheck.php has:
"field_label")
$form_fields = array(
"element0" => 'Your Name:',
"element1" => 'Your Email:',
"element4" => 'Item Number:',
.
);
and I added:
"my_id" => 'My ID Is:',
And this works!
So when I am on mypage.php and I enter a value into the form field
"my_id" it carries over and repopulates should the form fail validation.
But upon initial load of the page from my link of mypage.php?my_id=5
(so I am not getting there via a form submit) how do I get the value
into the form field?

it will take the variable to mypage.php as $_GET['my_id]
you can not expect a variable value set in to $_POST array to reflect

i guess, it's time to you to read about session_start() method and the

Is the error due to the fact I am JS & PHP together?

No it works fine. The most annoying thing in making it difficult to

As I said above, the error message does not always appear.
Is the error due to the fact I am JS & PHP together?
Any help in understanding what I am doing wrong is appreciated.

How is $item_id created? You've not shown that in your PHP script

$item_id=substr($item_id, 0, 5);
$_SESSION['item_id'] = "$item_id";
The above is where item_id is created and added to a session.
The important thing is that this error never showed up before until I
added the Javascript link below:
var oss_itemid = "";
var loadOSS = window.open("http://www.myurl/myfile.php?iid="; +
oss_itemid, "",
"scrollbars

When I was testing initially, I had removed the variable above in the
link with a hard coded value and I never received this error. Only
when I made it dynamic did this error appear.
Thanks for any help.

I'm assuming then that both the Javascript an the PHP code you have
above are both on the same page. The only way I can see your problem
occurring would be if your javascript part was on a different page
and you were attempting to output the $item_id. If PHP could not
find a variable with that name, it may be reverting to using the
item_id value found in $_SESSION, which would give you the error
you're seeing.
Yes this is the case.
However, what you said brings up a point if interest. The page that
the link is bringing up contains the following:
if ($_GET["iid"]=='') {
$item_id = ($_SESSION["item_id"]);
}
else
{
$item_id = $_GET["iid"];
}
This code determines if the user is getting there from the initial
link and if so, sets the variable item_id to the value passed in the
URL.
Again however, this was not returning errors when the link was
hardcoded with a value in place of item_id.

Because you've given it an array. Your original question never
mentioned
you were using parse_url() on the original array string. parse_url()
breaks the string into its component parts, much like my explode

[PHP] Replacing Registered Symbol
Hello List.
I'm trying to replace the registered (®) symbol from a variable via PHP.
The variable $mystring is set to a MySQL field that contains the value
"This Is The Registered Symbol ®".

I tried replacing the symbol in the above syntax with the HTML

[PHP] Stripping Characters

I need to remove characters from a string and replace them with and
underscore.
So instead of having something like:
$moditem = str_replace("--","_","$mystring");
$moditem = str_replace("?","_","$mystring");
$moditem = str_replace("!","_","$mystring");
etc.
For every possible character I can think of, is there a way to simply
omit any character that is not an alpha character and not a number
value from 0 to 9?

Hello again list.
My code for stripping characters is below. I'm hoping to get feedback
as to how rock solid it will provide the desired output under any
circumstance:
My output must look like this (no quotes):
"This-is-my-string-with-lots-of-junk-characters-in-it"
The code with string looks like this:
$old_string = 'This is my & $string -- with ƒ
lots˙˙˙of junk characters in it¡™£¢∞§¶•ªºœ∑´®†
¥¨ˆøπ“‘ååß∂ƒ©˙∆˚¬…æ`__';
$find = '/[^a-z0-9]/i';

$new_string = preg_replace($find, $replace, $old_string);
$new_string = preg_replace("/ {2,}/", "-", $new_string);
$new_string = preg_replace("/ {1,}/", "-", $new_string);
$new_string = rtrim($new_string, "-");
$new_string = ltrim($new_string, "-");
echo $new_string;
Will the logic above capture and remove every non alpha numeric
character and place a SINGLE hyphen between the non contiguous alpha
numeric characters?
Thanks for the help on this.

You can remove the second line of code, as the third one is
replacing what line 2 does anyway.
Also, instead of a rtrim and ltrim, you can merge the two with a
single call to trim, which will work on both ends of the string at
once.

[PHP] PHP Pill

Hi Ash. Yes, windows XP, I believe. PHP Pill is a FileMaker plugin that allows you to execute PHP from within your FM code.

But the plugin is working as it is removing everthing... but gets tripped on the trade mark symbol.

Problem I'm having is I've inherited a PHP page that contains sections of
PHP/Javascript/HTML/CSS all inside of a PHP echo tag. My PHP and JS skill are
rudimentary at best so when it comes to a block of code 40 to 50 lines in
length, it becomes daunting to reverse the ' with ". Each echo block starts
with a " and the html inside uses a '. JS also uses '.
Below is an actual block in more detail with JS in it. Is it still recommended
to switch with " with ' and ' with "?

echo "
Click on a picture to view that color:";
If (trim($pic_1) <> "") {echo " ";}
If (trim($pic_2) <> "") {echo " ";}
If (trim($pic_3) <> "") {echo " ";}
If (trim($pic_4) <> "") {echo " ";}

The whole page is like this that's why I said it was daunting : (
[PHP] Quotes vs. Single Quote
Hi List.
I've mentioned before that I am both just beginning to learn PHP AND I have
inherited a number of pages that I'm trying to clean up the w3c validation on.
Something that confuses me is how the code on the page is written where in one
instance, it follows this:
echo "
And elsewhere on the page it follows:
echo '
In what I've read and from many of the suggestions from this board, the latter
seems to be the better way to code, generally speaking.
So given that the page has javascript in it, perhaps the reason for the
previous developer switching between the two was for ease of incorporating
JS? Don't really know... but what I would like to know is it considered
poor coding switch between the two on a single page or is it perfectly
acceptable?
2nd question, in the 3 lines below:
$_SESSION['newpage'] = $newpage;
$checkstat = "select field from table where fieldid = $field_id";
$result1 = @mysql_query($checkstat,$connection) or die("Couldn't execute
query");
If I were to recode in the latter style, should they not look like this:
$_SESSION['newpage'] = $newpage;
$checkstat = 'select field from table where fieldid = "'.$field_id.'"';
$result1 = @mysql_query($checkstat,$connection) or die('Couldn\'t execute
query');
The focus being here:
"'.$field_id.'"';
('Couldn\'t execute query')
Is this correct?
Thanks for the help.

[PHP] PHP loop to issue sql insert
Hello List.
I have a sql command that counts, groups and sorts data from a table.
I need to insert the results of that sql command into different table.
My sql SELECT looks like this:
select count(*) as count, searchkeywords from searchtable group by
searchkeywords order by count desc;
and returns records like this:
578 green
254 blue
253 red
253 yellow
118 orange
etc.
My PHP looks like this so far:
$sql = "select count(*) as count, searchkeywords from searchtable
group by searchkeywords order by count desc";
$result = @mysql_query($sql,$connection) or die("Couldn't execute
checkcat query");
$num = mysql_num_rows($result);
echo $num;
The echo is of course returning the total number of records not
data as listed above.
I know a WHILE statement is to be used here, but can't get it to work.
How do I loop through the above found data, inserting each value as
like this:
insert into mytable (count, color) values ("578", "green");
insert into mytable (count, color) values ("254", "blue");
...etc
Thanks,

Personally I'll get MySQL to do it for me using: insert into mytable
(count, color) select count(*) as count, searchkeywords from
searchtable group by searchkeywords order by count desc (see http://dev.mysql.com/doc/refman/5.1/en/insert-select.html
for more information on INSERT ... SELECT)
Wow... I have never heard of the combination of INSERT... SELECT
before worked perfectly. Thanks.

[PHP] Parsing a phrase
Hello all. I have a page where the user can enter a search phrase and upon submitting, the search phrase is queried in MySQL. However, I need to modify is so each word in the phrase is searched for... not just the exact phrase. So, "big blue hat" will return results like: "A big hat - blue in color" "Hat - blue, big" SQL would look like WHERE (item_description like "%big%" and item_description like "%blue %" and item_description like "%hat%" ) So, via PHP, what is the best way to extract each word from the search phrase to it's own variable so I can place them dynamically into the SQL statement.

[PHP] Memory_Limit adjustments
Hello all. I am using a form combined with PHP to upload files to a website directory. Worked fine until I tried to upload a file 1.7 mb in size. My php code isn't the bottleneck as I scan the file first and reject the upload request if it exceed 4096KB. So I looked at the php.ini file and tweaked some settings. Once I changed the Memory_Limit setting from 8mb to 28mb, the file upload without a problem. So, my question is, is the 28mb setting going to cause problems elsewhere on the server or is this a relatively modest setting? Should I adjust it further? The server is a Linux server running Apache 1.3.37 with PHP version 5.2.3. Current memory usage as follows: Current Memory Usage total used free Mem: 21898120 283912 21614208 -/+ buffers/cache: 283912 21614208 Swap: 0 00 Total:21898120 283912 21614208 Thanks for any help. --Rick -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

$code ='Hello World';
$key = 'my key';
function decrypt($code, $key) {
$key = hex2bin($key);
$code = hex2bin($code);
$td = mcrypt_module_open("rijndael-128", "", "cbc", "");
mcrypt_generic_init($td, $key, "fedcba9876543210");
$decrypted = mdecrypt_generic($td, $code);
mcrypt_generic_deinit($td);
mcrypt_module_close($td);
return utf8_encode(trim($decrypted));
}
function hex2bin($hexdata) {
$bindata = "";
for ($i = 0; $i < strlen($hexdata); $i += 2) {
$bindata .= chr(hexdec(substr($hexdata, $i, 2)));
}
return $bindata;
}
echo decrypt($code, $key);
The above returns output containing a series of unprintable characters.
I thought maybe it was due to $code not being in a hex format, but after
converting to hex and resubmitting, I still unprintable characters.
Any info is appreciated.

Hi all. We were able to get it to work. But thank you for your replies.
But for anyone interested (including anyone who has emailed me privately
implying I was up to something untoward), the specs from the client were as
follows:
Unencrypted: "2012-10-18T10:57:43+0200 someurl.com"
Encrypted + base64: "ch7WvaSrCiHLstNeNUp5SkPfPGqZ8vrNPJT+9vU7jN/C"
Encrypt algorithm: AES/CBC, PKCS5Padding, IV of 16 NULL (0x0 hex) bytes
Key: "someKEY123-12346"
$iv = mcrypt_create_iv(32);
$key = 'someKEY123-12346';
$text = '2012-10-18T10:57:43+0200 someurl.com';
$size = mcrypt_get_block_size('rijndael-128', 'cbc');
$text = pkcs5_pad($text, $size);
$crypttext = mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $key, $text, MCRYPT_MODE_CBC,
$iv);
$decrypttext = mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $key,
base64_decode('ch7WvaSrCiHLstNeNUp5SkPfPGqZ8vrNPJT+9vU7jN/C'), MCRYPT_MODE_CBC,
$iv);
function pkcs5_pad ($text, $blocksize)
{
$pad = $blocksize - (strlen($text) % $blocksize);
return $text . str_repeat(chr($pad), $pad);
}
echo $decrypttext;

[PHP] Pear Mail - Trap for errors?
Hello all.
I have some Pear Mail code composing an email and sending it to an external
smtp server for sending.
The issue is determining whether that external server actually accepted the
mail or not. In the IF(PEAR… code below, it will return success even if I
leave the $to value empty. However, if I remove the smtp username or password,
it will return an error indicating it could not reach the remote server. So
the Pear::IsError function seems to only reflect if the intended server was
accessible… and not if the intended server accepted the outgoing email for
delivery.
Anyone have experience with the scenario below… specifically with determining
if the smtp server accepted the mail for delivery?
Thanks for any info.

Same result… which is to say no error returned even for messages sent with no

[PHP] Can't connect to MySQL via PHP
Hello all. I used the code below successfully to connect to a MySQL db on one hosting provider. I've moved the code to a new hosting provider with new values and it returns: Access denied for user 'user'@'db.hostprovider.net' (using password: YES) Even though I can copy and paste these three values (host, user and pass) and paste into Navicat to make a connection. So the credentials are correct, but they are not authenticating when used in PHP. I've tried making host "localhost" and "127.0.0.1"… both with the same result. Can someone tell me what I am doing wrong here? Appreciate it.

Re: [PHP] Can't connect to MySQL via PHP
Hi Jim, and all the rest. Thanks for the help. What was throwing me was the EXACT same creds were being used to connect via Navicat… but not when using PHP. Could not figure it out. So I zapped gremlins in BBEdit on my test file.. which had literally no more lines than what I posted to this list… not expecting it to work since the code was so simple and I saw nothing out of place…but it did, I connected after that. So some character had to gotten placed into the file when moving from one hosting provider to another. Thanks to all who offered help regarding the connection issue. --Rick On Jan 13, 2013, at 12:12 PM, Jim Giner wrote: > Regardless of the choice of interface to mysql, regardless of the completely > harmless but educational tips from Ash, and very deliberately ignoring the > un-helpful and extraneous comments of others, > I'm wondering how the OP is doing with getting his mysql access working. > Haven't heard from him lately. > > Rick? > > -- > PHP General Mailing List (http://www.php.net/) > To unsubscribe, visit: http://www.php.net/unsub.php > -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Destroying cookies... not working
Hello all.
I have a logout page that should be destroying cookies when loaded...
but it is not.
setcookie("mycookie", "False", time() - 3600, "/");
However, I can still pull values stored in the cookie and I can still
see the cookie in my browser's "Show Cookies" window.
So I tried the following:
setcookie('mycookie','',time()-3600);
unset($_COOKIE['mycookie']);
Still no luck.
Any help with this is appreciated.

[PHP] PHP Rounding Question
I have a division formula that will return an value from 0.00 to 5... so I can get values like 2.38 or 4.79. However, never lower than 0 or higher than 5. How do I coerce the result to always round up to the nearest increment 1/4?

[PHP] Displaying variables in text - clarification needed
Hello all. I inherited some PHP pages about a year ago. They have been fine all along but now a bunch of erroneous errors and results are popping up. I traced it to the way the variables were being used on the page... for example, the following SQL statement (a space between ' and " for clarity): sql="select name from mytable where name=$myvar and display='yes' "; This has worked in the past but is now returning errors for some records and working for others. I changed the above to the following and now all is good: sql="select name from mytable where name=' ".$myvar." ' and display='yes' "; What would explain why the former is suddenly causing problems? The version of PHP is 5.2.3 and from what I can tell, hasn't been updated since February of 2011.

[PHP] function.session-start in Webmaster Tools
Hello all. Not sure just how much of this is PHP related, but hoping someone has come across this before.

I read up on the error itself... sometimes caused by whitespace before the session_start tag... have fixed that. Any info is appreciated. --Rick
Re: [PHP] function.session-start in Webmaster Tools
But those pages, when loaded, do not display any PHP errors. Only webmaster tools is showing the function.session-start in a link to that page. When I looked up hte meaning of session-start function, I found others who have indicated that white space in front of the session tag can cause this... so I eliminated it. Not sure if that will fix as the page has never displayed an error and Google takes forever to recrawl the whole site. --Rick On Oct 31, 2011, at 5:44 AM, Stuart Dallas wrote: On 30 Oct 2011, at 20:30, Rick Dwyer wrote: Hello all.

[PHP] mcrypt_encrypt help needed
Hello all.
I am using the following function to encrypt a string:
define('SALT', 'myvalueforsalthere');
function encrypt($text)
{
return trim(base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_256,
SALT, $text, MCRYPT_MODE_ECB,

}
and then:
$myval="hello";
$mayval= encrypt($myval);
echo decrypt($myval);
returns "hello" great.
But when my input string is more complicated I get unprintable
characters out of the decyrpt side:
$myval="var1=1&var2=2&var3=3";
The above when decrypted will spit out a string of unprintable
characters.
Is encrypt/decrypt choking on the "=" sign? I tried:
$myval=htmlentities($myval);
But it did not work. Any help is appreciated.

Hi Rick,
Can you show us the decrypt function, too (even though it should be
just
the reverse order of operations using a decrypt function, I'd just
like to
double check it before commenting.) By the way, I wouldn't recommend
using
ECB mode unless you have a special circumstance:

The + symbol is then interpretted as a space instead of + symbol and a result, my decrypt function fails. So I send off the encrypted value encoded to PayPal but when they go to redirect back to my site after payment has been made, instead of the url with Sw%2Bht0agaQRBpFlfHSucpYZ in it, they are decoding it so my url contains Sw+ht0agaQRBpFlfHSucpYZ which causes me problems.

Now you say you use $_GET["myval"], which means you get them from URL. Base64 is not URL safe, have you used urlencode()? Matijn OK, the problem appears to be that my string encoded contains a + symbol: Sw+ht0agaQRBpFlfHSucpYZ So I rawurlencode it and if I echo it out, it appears correctly on the page as: Sw%2Bht0agaQRBpFlfHSucpYZ BUT... when I pass this encrypted value off to PayPal (I'm integrating with them), encoded, when they return me to my site, instead of passing me my value as above, they are somehow decoding back to the original: Sw+ht0agaQRBpFlfHSucpYZ As I can see it in the URL. The + symbol is then interpretted as a space instead of + symbol and a result, my decrypt function fails. So I send off the encrypted value encoded to PayPal but when they go to redirect back to my site after payment has been made, instead of the url with Sw%2Bht0agaQRBpFlfHSucpYZ in it, they are decoding it so my url contains Sw+ht0agaQRBpFlfHSucpYZ which causes me problems. Is there alternative encrypting scheme that will not need url encoding (so I can be sure the passed url back from PayPal is ok as is)? --Rick It seems normal to me that it is decoded, I think that's how it's supposed to work. How about urlencoding it twice? That might just work. Other possibility is to send it as a string of hex characters using hex2bin or something like that. Matijn Yes! Thanks, double urlencoding it did the trick. I first encrypt it followed by a double rawurlencode. Thanks... my head was beginning to really hurt from banging it on the wall. --Rick -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Preferred Syntax
Hello all. Can someone tell me which of the following is preferred and why? echo "$page_name"; echo "".$page_name.""; When I come across the above code in line 1, I have been changing it to what you see in line 2 for no other reason than it delineates out better in BBEdit. Is this just a preference choice or is one method better than the other? --Rick -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I was concerned that not breaking the VARS out separately from the echo'ed text might cause some sort of performance problem or confusion for PHP. Therefore, whenever I came across them, I was breaking them out with the . $var . technique. Will no longer do that for existing code, as it appears not necessary, but I do prefer it for readability sake... expecially in BBEdit. So will continue to write new code breaking it out. And I too prefer a single quote for PHP and a double for HTML... even though the sample I displayed showed otherwise. Thanks to all who responded. --Rick
[PHP] PHP page source charset
Hello all. When I set my page charset from iso-8859-1 to utf-8, when I run it through the W3C validator, the validator returns an error that it can't validate the page because of an illegal character not covered by UTF-8. "Sorry, I am unable to validate this document because on line 199 it contained one or more bytes that I cannot interpret as utf-8(in other words, the bytes found are not valid values in the specified Character Encoding).

[PHP] Curl problems
Hello all. I use curl to make a call to another page on my site... but it operates erroneously sometimes working... sometimes not. The page it calls creates an email and I can see on the server the email in the queue when it's working. If I echo out the URL the curl command is supposed to load and load it manually, it works without fail. Any help on what I am doing wrong below is greatly appreciated. Thanks. $curl_handle=curl_init(); curl_setopt($curl_handle,CURLOPT_URL,'https://mydomain.com/email_confirmation.htm?id_order='.$id_order.'&sess_id='.$sess_id) ; curl_exec($curl_handle); curl_close($curl_handle); --Rick -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Form Post to different domain

Re: [PHP] Form Post to different domain
Thanks Dan.
As it turned out the reason for not showing the passed values is that
I didn't have "www" in the destination address and the values must
have been getting lost when Apache redirected requests without www to
the fully formed URL.

Then all you should need to do is:
a.) Verify that Domain A is indeed pointing to Domain B, to
the script you expect, as a POST request.
b.) In the POST-receiving script on Domain B, try this simple
snippet:
'.PHP_EOL;
var_dump($_POST);
die('');
?>
That should give you all data from the post request.

[PHP] Selecting checkboxes based on SQL query
Hello all. I perform a SQL query like the following: $sql = 'select * from my_table where id="10" It returns the the following array for 3 records: Array ( [0] => Array ( [cb] => 2 ) [1] => Array ( [cb] => 6 ) [2] => Array ( [cb] => 1 ) ) The values of CB in the above array are the values of html checkboxes on a page. input type="checkbox" name="cb[ ]" value="1"... input type="checkbox" name="cb[ ]" value="2"... input type="checkbox" name="cb[ ]" value="3"... input type="checkbox" name="cb[ ]" value="4"... etc If the above array's cb value matches the value of a checkbox on the page, I need the default state of the checkbox to be checked so I know I'm going to have some ternary logic in each html checkbox. But I don't know how to create a custom function from the above array to provide that logic. I've tried some tutorials, but with no success as the array I am receiving is not like those in the tutorials. Any help would be greatly appreciated. Thank you. --Rick -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Selecting checkboxes based on SQL query
I should have been more explicit in my description...
The SQL command that returns the array is not the same one that
creates the checkboxes they are two different sql queries and I
would prefer to keep them that way.
I actually have it working for a form submit with a custom function I
got off the web. But the custom function relies on the array it's
working on to look like this:
[cb] => Array ( [0] => 1 [1] => 6 [2] => 2 [3] => 4 [4] => 3 )
So, to use my existing function, how do I get the following array to
look like the above one:
Array ( [0] => Array ( [cb] => 2 ) [1] => Array ( [cb] => 6 ) [2] =>
Array ( [cb] => 1 ) )

replace the name part as following
input type="checkbox" name="cb[put_the_id_here]" value="1".
when dumping into html from array
foreach ($sql_result as $value) {
if ($value == $selected) {
input type checkbox name=cb[$value['id']] value=$value['id']
checked=checked
} else {
input type checkbox name=cb[$value['id']] value=$value['id']
}
}
hope this helps
