[PHP] Re: no newline after "?>" in the resulting HTML

Hi,

I've tried to ask the following question on internals@lists.php.net but
has been pointed out that that mailing list isn't appropriate. So I'm
resinding it here.

I am a newbie to PHP. I've installed a php5-cgi-5.1.2_1 from FreeBSD
ports collection and access it by FastCGI protocol from nginx HTTP
server. I've tried an example of "Hello World" PHP script from the
following tutorial page:

http://www.php.net/manual/en/tutorial.firstpage.php

This is how the resulting HTML code is expected to look like, according
to the tutorial:


 
 PHP Test
 
 
 Hello World
 


And following is the HTML code I've got:


 
 PHP Test
 
 
 Hello World


Why there is no newline afer " Hello World" ?
Is it a PHP bug or the tutorial should be updated?

P.S. I'm not subscribed to this list, please Cc your reply.






I get the same results, I doubt it's a bug, the person who wrote the 
article maybe never tried what it would output since they probably know 
how the echo construct works, if you want a line break you should change 
it to:-



Hello World\n"; ?>

or:-

Hello World" . PHP_EOL; ?>

or:-

Hello World
"; ?>

Hey everyone, probably missed the bit in the manual but my current

My guess would be to set the ./configure line to something like 
--with-config-file-path=/home/*/public_html


but I dont wanna re-compile if im wrong, can anyone tell me?

Nothing special on my configure line and the setting:-
Configuration File (php.ini) Path looks like /home/USERNAME/public_html

Only just noticed it's been switched over to CGI recently, It's also 
possible to have one php.ini per directory and the above mentioned 
setting always reflects the php.ini setting for that directory so must 
be something concerning httpd.

[PHP] Re: Caching problems .. I think

SOunds like your form is using POST which does what you desribe to avoid 
submitting the same info twice. only way I know is to use GET but that 
would put al data in the URL.

Hi guys

I have a rather simple setup:

A few forms chained after each other (the first leds to the second which

I´m using sessions - and starting each page like this:

header('Expires: ' . gmdate('D, d M Y H:i:s', (time() + (60 * 10))) . ' 
GMT');

session_cache_limiter('private_no_expire');
session_start();

... which I believe gives each page (and form result) a caching time of 
10 minutes. The problem is that when using the back button in IE - IE 
complains about the page and tells med that this page is the result of a 
form and that the content has been blocked.


Can anyone tell me how to awoid this problem, so the backbutton can be 
used, and stil give each page a caching time of 10 minutes?

[PHP] Re: Preference for User Permissions system

[James Benson]

What I do is have different classes that build upon each other,


authentication & permissions class,
common database access extending PEAR DB.

then i have a custom class for specific actions like editing pages, my 
database is just either either an email or username and password then 
another table has permission levels in, permissions for every user are 
defined in their DB table in a comma seperated list, that way i can 
create many groups and have a user belong many groups, then page editng 
for instance can be restricted to specific users or groups, I designed 
it all to be flexible enough to reuse for all my websites I hope :)

James

[PHP] Re: Email Validation built-in? RFC

[James Benson]

It would be nice to have a php function valid_email or something but 
until then i suppose we just make do with what is available, for what I 
need I use the following:-



eregi("^[a-z0-9]+([_\\.-][a-z0-9]+)*" 
."@"."([a-z0-9]+([\.-][a-z0-9]+)*)+"."\\.[a-z]{2,}"."$",$email)



Ive never had problems with it but have up to now no need for 
multilanguage validation.



What is wrong with that validation anyway?







Richard Lynch wrote:

Given:

It is unacceptable to reject perfectly valid email addresses, no
matter how arcane. [Like mine. :-)]

The CORRECT RegEx for validating an email is 3 pages long, and
performance in PHP would probably not be so good...

In today's Security-conscious world, data validation is a requirement.

The (relatively) recent changes in domain names that allow UTF
(Unicode?) characters.

Checking MX records is not reliable at all.

Forcing users to respond to email is A) burdensome to real users in
many cases, and B) no real barrier to halfway intelligent fake users.

... would it not make sense for there to be a BUILT-IN PHP function of
a TRUE email syntactic validation?

So at least one KNOWS that the email is a valid construct, before you
even try (if you try at all) to make sure that a person actually
checks it at least once in their life.

Currently, email syntax validation is being done in very limited
fashion, if not outright "wrong" by rejecting what actually ARE valid
email addresses in about 10,000,000 PHP scripts by users who don't
have any realistic options to truly "do it right" because who can
really live with that 3-page Regex in their PHP code?

Yes, in the past, I may have come down squarely on the opposite side
of this topic, but I've changed my mind.

I believe PHP needs a built-in syntactically CORRECT email validation
function, vetted and tested by professionals, instead of the mess we
now have.

PLEASE do not point me to any existing email validation code unless
you believe it is not only 100% correct and complete with RFC
definitions of syntactically valid email.  Not interested.  I've
already seen them, and been burned by them.

Hello,

On my site right now if someone searches for "511" (a misspelling of the
manufacturer 5.11) they are not presented with the right products
because 511 is not found anywhere in the database.

I've got a few ideas on how to solve this but I want to find one that
requires as little administrative overhead as possible.

1. I could add a field to the db for each product that would be used for
associated words for a product as well as misspellings.

PROS: Very customizable on an individual product level.
CONS: Would need to be updated for each and every product individually.

2. Make a field for each manufacturer's record for alternate
spellings/keywords.

PROS: Little administrative overhead.
CONS: Is only manufacturer name based and could not account for specific
products.

3. Both #1 and #2.

PROS: Flexible.
CONS: Lots of administrative overhead.

4. A one-to-many table that associates individual words with product
skus. This one is pretty much the opposite of #1 with one key
difference: the interface. It would be probably be easier to enter a
desired word and then choose each sku from a multi-select dropdown than
it would be to go from product to product entering one word at a time.

5. I'm not sure how this would be accomplished from a technical
standpoint but it would be nice to have the program know that when
someone types in "511" they really meant "5.11". Or (hopefully this
isn't a bad example) if they type in "dessert" (as in cake and icecream)
they really meant "desert" (as in snakes and sand).

In my case that wouldn't be a bad assumption since our site will never
contain the word desert unless it's a misspelling.


What does everyone think? What other options are out there?

[James Benson]

Did you actually test that?


Even better version of your function,





$string = "one two three four";

echo substr($string, -4);
echo '...';

Finally i found it (Google is god, you only have to ask the right question)
 function trim_text($text, $count){
$text = str_replace(" ", " ", $text);
$string = explode(" ", $text);
for ( $wordCounter = 0; $wordCounter <= $count;wordCounter++ ){
$trimed .= $string[$wordCounter];
if ( $wordCounter < $count ){ $trimed .= " "; }
else { $trimed .= "..."; }
}
$trimed = trim($trimed);
return $trimed;
}

Usage

$string = "one two three four";
echo trim_text($string, 3);

Subject: Substr by words
To: php-general@lists.php.net

 Hi,
 I need to extract 50 words more or less from a description field. How can i
do that?. Substr, cuts the words. Is there any other way to that, without
using and array? I mean and implemented function in PHP 4.x
 I´ve been googling around, but wordwrap, and substr is driving me mad...
 Thanks in advance
Best Regards

No, its not possible without asking the client to install some software!

Re: [PHP] Re: Managing files on the client

[James Benson]

javascript CANNOT write to a clients machine (apart from cookies)

Nothing from the server can do what you want, you need to install some 
software on each machine to achieve this.

[PHP] Re: PHP web based administrator... Pyrite

[James Benson]

It should be fine for windows but how are you gonna save the php.ini on 
any linux box that typically (when setup correctly) requires root access 
to save the file, your opening up a security hole with something like 
that unless you tackle this issue some other way!

Hi list

I have been working on a free web based app that lets you update the
php.inifrom your browser very much like Coldfusion has.

You can find a demo off the app at
http://pyrite.zacbarton.comand im
looking to see if anyone thinks this might be useful or share any
ideas/comments
before I take it any further.

The demo site is pointing to a test php.ini file so feel free to play with
it.

[PHP] Re: Richard Lynch's Email Address ...

[James Benson]

Would it not be better something like valid_email()

Reason:
The is_* family check for a variable type so dont think that it really 
fits into the same catagory.



James




Jochem Maas wrote:

I totally agree with Richard. about the need for
a php func for checking a correct email addr.

given that php 'is all about the web', idealogically
(still?) pragmatic and dynamically typed:

is_email_addr() or is_email()

just 'belongs' with:

is_array()
is_bool()
is_callable()
is_double()
is_float()
is_int()
is_integer()
is_long()
is_null()
is_numeric()
is_object()
is_real()
is_resource()
is_scalar()
is_string()

any devs care to comment?

kind regards

How about substr_replace()

Greetigns Gents,

I seem to remember a built in php function that will take a huge block of
text.
Then just spit out X number of characters from it and follow it with an
additional string value.
But I cannot remember what it is.

I seem to remember it being something other than the substr().

I am looking to pull the first say 200 characters from an article and follow
the last character/word with something like ...

Does anyone know what I am talking about, or am I just smoking something and
my memory is going?

Blessed Be

[PHP] performance suggestions

[James Benson]

Dear group, can someone suggest the best way to do the following without 
writing some lengthy script that (possibly) could lead to performance 
issues,



I have three DB fields in MySQL, each has a unique ID, I cannot think of 
any ways other than pulling each tables record then looping through to 
determine which one each belongs to which group then maybe placing into 
an array,

the association between them all goes like this,


URL:-
url_id
url_name

section:-
section_id
url_id
section_name

page:-
page_id
section_id
page_name



What I need to do is construct a navigation bar with each url, section 
then pages for that section, is their any quick ways (perhaps with SQL) 
anyone knows of,


A static array im currently using for this looks like:-

$nav = array(

1 => array('title' => "Homepage",
'url' => "/main::default"),

2 => array('title' => "About",
'url' => "/main::about",
'sub' => array(
array('title' => "Contact",
'url' => "/main::about::contact"),
)
),

);



Hope that makes sense to someone.



Thanks in advance for any suggestions/help


James

[PHP] Re: PHP MYSQL Dynamic Select Boxes: Please Help

[James Benson]

Try asking in a newsgroup or forum specific to javascript, that has 
nothing to do with PHP






Adele Botes wrote:

I have 2 tables:

products table
product_id (INT 11 AUTOINCRE PRI)
product_name (VARCHAR 255)
product_desc (VARCHAR 255)

color table
color_id (INT 11 AUTOINCRE PRI)
color (VARCHAR 255)
image (VARCHAR 255)
product_id (INT 11)

I would like to create the first select box (pulling the options from 
the products table).


Then I would like the second select box to display the color option 
related to the product_id in the first select box, thus changing the 
options dynamically.


I've tried the following and it doesn't seem to work.
What am I doing wrong? Please help:

window.onload = function() {
dynamicSelect("pda-brand", "pda-type");
}





Select a product...
$product_name";
}
?>



Select a 
color...

$sql1 = mysql_query("SELECT * FROM `products` LEFT JOIN `color` 
ON products.product_id = color.product_id WHERE color.product_id = 
'$product_id'");

while ($row = @mysql_fetch_array($sql1))
{
$product_id = $row['product_id'];
$color_id = $row['color_id'];
$color = $row['color'];
//print "$product_id $color_id $color";
print "value='$color'>$color";

}
?>






This is all the JavaScript code i used:
function dynamicSelect(id1, id2) {
// Feature test to see if there is enough W3C DOM support
if (document.getElementById && document.getElementsByTagName) {
// Obtain references to both select boxes
var sel1 = document.getElementById(id1);
var sel2 = document.getElementById(id2);
// Clone the dynamic select box
var clone = sel2.cloneNode(true);
// Obtain references to all cloned options
var clonedOptions = clone.getElementsByTagName("option");
// Onload init: call a generic function to display the related 
options in the dynamic select box

refreshDynamicSelectOptions(sel1, sel2, clonedOptions);
// Onchange of the main select box: call a generic function to 
display the related options in the dynamic select box

sel1.onchange = function() {
refreshDynamicSelectOptions(sel1, sel2, clonedOptions);
};
}
}
function refreshDynamicSelectOptions(sel1, sel2, clonedOptions) {
// Delete all options of the dynamic select box
while (sel2.options.length) {
sel2.remove(0);
}
// Create regular expression objects for "select" and the value of 
the selected option of the main select box as class names

var pattern1 = /( |^)(select)( |$)/;
var pattern2 = new RegExp("( |^)(" + 
sel1.options[sel1.selectedIndex].value + ")( |$)");

// Iterate through all cloned options
for (var i = 0; i < clonedOptions.length; i++) {
// If the classname of a cloned option either equals "select" or 
equals the value of the selected option of the main select box
if (clonedOptions[i].className.match(pattern1) || 
clonedOptions[i].className.match(pattern2)) {
// Clone the option from the hidden option pool and append 
it to the dynamic select box

sel2.appendChild(clonedOptions[i].cloneNode(true));
}
}
}
// Attach our behavior onload
window.onload = function() {
dynamicSelect("product_name", "color");
}

Thx in adv
