[PHP] fwrite() blank-line Quirk?
Hi All, Relatively new PHP coder (was in an MS / ASP shop before)... I'm doing some flat-file manipulation (please, spare me the database comments, I'm working on it!), and I'm having to read strings out of one file and copy them into another until a while() condition is satisfied. The problem is, I seem to always end up with a blank line at the end of my files (which then screws up later file-processing) - I'm assuming because of the \n that fwrite() appends to the end of each string... Is there a simple way to get rid of this blank line or somehow get fwrite() to NOT put a newline on the end of a string?

[PHP] fgets() question?
Okay, attacking my flat-file issues from the other end:
When you use $foo = fgets($fp_file); it appears that a blank line ends up
looking exactly like a FALSE ("failed to read") return value... Is there
any way to differentiate between an empty-string read (a blank line in a
flat-file) and a FALSE return from fgets() ??
Thanks a bunch,
--Noel

> A blank line should return the newline (\n or \r\n), according to > http://www.php.net/manual/en/function.fgets.php. Also try using '===' (3 = > signs) as the operator, which enforces type checking on a comparison). Yes or no: $foo == FALSE === 0; ??? Right now I'm just doing if($foo) And "\n" seems to equate to FALSE with this sort of conditional / comparison...

[PHP] Passing Query_String or variables through multiple pages?
Hi all, I have an issue I'm hoping there's a simple answer for (I'm betting there is): I have a dynamic page where the user may click on a link - this link processes their data and shows them a "result" page... Then I want a variable (for a manual hypertext link) that contains the original URL they were viewing. The problem is, the original page / URL needs a query string (i.e. "?key1=val1&key2=val2&key3=val3..."). So I have to somehow pass their original query string THROUGH the "result page" via a GET, and without using a (using a POST form I could do it)... I've looked at manually copying and "forwarding" each original variable by including it in the URL for the "result page"; but I was hoping for something more elegant and flexible... Any thoughts or ideas? Thanks a bunch in advance! Take care, --Noel -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Can you insert into $_POST manually?
Hi all, So I have a page that processes information and then "echo"s out a redirect that looks like this: The thing is, there are some variables that I would love to pass in $_POST or $HTTP_POST_VARS to the page referred to in "$url". Is there any way to stuff this data into either of these globals so that the "$url" page can access 'em?

[PHP] Re: session not set, server configuration?
James -
Don't know how you're working with Cookies and sessions for sure, but the
default / "easy" way to check for an established session is to put
"session_start();" at the top of every page that's going to access the
session variables. That will check for an established/open session and make
the registered session variables accessible to the page.
Then a logical check is as simple as using "session_is_registered()" like
this:
if (session_is_registered("registered_variable_name"))
//do something here if the person has already registered their session
else
//session not registered!
Hope this helps!
Take care,
--Noel

Re: [PHP] Can you insert into $_POST manually?
Thanks - I understand that method; but I'm really looking for a way to pass them without them being visible / mucking up the URL line with a buncha stuff... Take care, --Noel -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Can you insert into $_POST manually?
This will work perfectly! Actually, building a dynamic javascript function and/or hidden form will allow me to collapse a couple of other redirect systems on my site into one...

[PHP] Re: how to passing two dimension array
You're missing string concatenation operators. I use "echo" instead of "print" - but here's how it should look with either: echo ""; Explanation: The \" makes the double-quote appear in the final HTML, then you have to use a plain " to end the text string. Then you use the . concatenation operator, followed by your variable. To add further text, use another . operator, then " to open up the text string, then \" for the HTML close-quote, then the > to close the HTML tag, then " to close out the echo or print statement. End with a ; Let me know if that helps!

[PHP] Re: how can I use an external 'template' file and still use PHP variables?
I agree with Edwin on this one.
What's the <<< for??
Could it be you want to be doing this:
$templatestring = include("/pathto/email_template.php");
$message = "<<" tags
will be considered plain text. Put another way: Even though the "include"
statement in the main document is ALREADY between PHP tags, the parser looks
for an opening PHP tag in the included file to find where to begin parsing -
anything before that opening tag is echo'ed out as plain text).
Hope this helps!
Take care,
--Noel

[PHP] Session vars vs. POST/GET vars?
Hi all,
So I have a session variable; but with register_globals active on the server
I'm hosted at (no way to turn it off), just checkng for "$varX" in my script
could retrieve the session variable, a GET variable with the same name, or a
POST variable with the same name - and as a security concern, someone could
use a GET request (http://somehost/mypage.php?varX=0) to spoof the script
into thinking that "varX" is the wrong value.
So, is there any way in a script to specify that I want to retrieve the
value stored in the registered session_variable("varX")??
Thanks,
--Noel

[PHP] SELECT MULTIPLE form variable?
Hi all, So I was under the impression that an HTML form "SELECT MULTIPLE" item would return an array with all of the selected items. This array can then be used with any of the standard PHP array functions, yes? I have 1 HTML page that seems to work fine... However, another page that is nearly identical is failing - giving me the following error: "Wrong datatype for second argument in call to in_array". When I look at the variable, it seems to ONLY contain a string - the first item the user selected. The only difference I can see is that the working SELECT MULTIPLE has numerical values, and the dysfunctional one uses string values - but the values ARE enclosed in quotation-marks... so I don't know why they're not POSTing properly as an array. Is this a known bug or issue? Any thoughts or solutions? Thanks a bunch, take care, --Noel -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] SELECT MULTIPLE form variable?
Its the littlest things that kill ya Thanks a ton! As a side note, I definitely do NOT have the brackets on the working page - so its an undefined "feature" (or bug) that numerical-value SELECT MULTIPLE variables post as an array to PHP.

Re: [PHP] Re: php editor?
My favorite little gem is a shareware program called Code-Genie (www.code-genie.com). Its cheap, fast, a "slim" app, provides tons of useful little features, and has TOTALLY user-configurable text-coloring. You can specify a particular coloring scheme for each file extension, so it automatically picks the scheme for the type of programming you're doing - very handy! Comes with schemes for all of the most common / simple programming languages, plus plenty of user-made files for download, too! It doesn't have any real debugging features, nor can it do fancy things like track your custom object-functions and color them or present their arguments - but for a quick, simple, helpful tool - its just perfect!

Re: [PHP] Re: PHP help/example for booking program
Welcome, hope you enjoy PHP - its a great language! My best suggestion is to check out the book "PHP and MySQL Web Development" by Luke Welling and Laura Thomson - it provides you with all of the PHP & MySQL fundamentals and good concepts for how to design something like that. The book is aimed a little bit more at people who can already do some programming; but you should pick it up to start with, and if it doesn't make sense grab a smaller "beginner" book on programming and then come back to "PHP & MySQL" Good luck!

[PHP] Forms / Array Question...
Hi All, Quickie Question... Possibly a silly one; but it would make my life easier if it works! I know that with a SELECT MULTIPLE, you have to use the convention: NAME="$varName[]" to get all of the responses into a nice neat array. I'm wondering about the mechanism behind this - is it simply doing a behind-the-scenes "$varName[] = X;", "$varName[] = Y;", "$varName[] = Z;" operation to dynamically generate the array? (Note: this is not my main question - keep reading. :-P ) If so, then it would follow that it's also possible to do something like this: ... And get a nice array with your text values. Anyone know if this (A) works and (B) is not actually just some undefined behavior that's risky to use? Thanks! Take care, --Noel
