PHP - Quick Question On Calling Js Function Inside Php Varible

I need to call usort from a class function, and I'm puzzled about how to define the comparison function.

I've tried to define the comparison function in the same class, but I can't get usort to call it. I found one hint that it will work if I make the comparison function static, but I tried that, and it didn't work for me.

If I define the comparison function outside the class, it won't have access to object properties that it needs to operate.

The only solution I can think of is to define the comparison function outside the class and put the object properties it needs in globals. Is there a cleaner way to do this?

Hello all, I have some piece of code that is nested like this


$variable = 'This is a global argument';
function parentFunction($variable) {
function childFunction() {
echo 'Argument of the parent function is '.$GLOBALS['variable'];
}
childFunction();
}
parentFunction(5);


What I want to know is - Is there a way to access a variable from the parent function without passing arguments to the child function? (Something like how classes have parent::?). I don't want to use $GLOBALS because it might cause some variable collision, and I didn't want to pass arguments because incase I decide to change the arguments in the parent function I'd have to do it in the child function aswell. From my searching around in the Internet it seems like this is not possible, but if theres a slight chance that there might be something out there, i'm willing to give it a shot .

Thanks in advance

i am accepting username by post and feeding it to variable in $username..help me

This is just a warning when you switch to PHP 5.3, you'll start seeing NOTICE messages on your page if you access a variable which is not exist or initialize. For example

$id=($_GET["id"]);
if ($id='home)

If there is no value to id because it's not part of the link, you'll get an error. These kind of notice messages are not shown in PHP 5.2.

Hi, I got a little problem with calling a PHP function from a href.
I got my site all set up, and am calling the function like this:

Code: [Select]
<?php echo '<a href="'.changeRecentPosts().'" class="image">' ?>
This does indeed work, but it calls the function every time I refresh my page.. Which isn't the effect I was trying to achieve.

I tried to change it to : Code: [Select]
<?php echo '<a href="#" onClick="'.changeRecentPosts().'" class="image">' ?> But that didn't work either.

It also seems it only calls it when I refresh my page, but never when I click it (I guess because PHP is handeled before HTML or something similar?).

If you can think of any way (even in AJAX, or whatever other language...) feel free to, I think I can figure it all out.

Thank you! 

I am using simple machines forum, and by placing a link to ssi.php in the top of my php page Code: [Select]
<?php require_once('/forum/SSI.php');?>I am able to use some ssi functions. My problem is calling another function from within a function. My first function is this:
Code: [Select]
<?php

$allowed_groups = array(1,5);
$can_see = FALSE;
foreach ($allowed_groups as $allowed)
if (in_array($allowed, $user_info['groups']))
{
$can_see = TRUE;
break;
}

if ($can_see)
{
echo '
<div>
this is text that i want certain groups to see
</div>';
}
else
{
//message or section to show if they are not allowed.
echo 'this is text that i dont want certain groups to see';



}
?>
This is my second function:
Code: [Select]
<?php ssi_welcome(); ?>
I want to put the second function inside the first function, like so:
Code: [Select]
if ($can_see)
{
echo '
<div>
<?php ssi_welcome(); ?>
</div>';
this just gives me the "<?php ssi_welcome(); ?>" displayed on the actual site, it is not calling the separate function.

I have tried different approaches, e.g. $function ssi_welcome;  but all it does is display this as text as well..

Please can some one point me in the right direction. Thank you

Does storing multiple values in 1 database field with a varchar let's say set at 150, all separated by
"|'s" so I don't have to create a field name for each one is it better performance wise or no? (storing 6-7 different |'s that will be outputted with a array ofc)

?

how to open a site with curl that has frames ?

when ive tried it gives "your broswer does not support frames" ...

What is the difference between these two lines


Code: [Select]
!isset($_POST[$requiredField])
and

Code: [Select]
!$_POST[$requiredField]

I am starting to learn PDO by re-writing one of my existing scripts. Do I still need to validate $_GET or does PDO do the work for me?  Currently I am using:

Code: [Select]
$id = $_GET['id'];

$sth = $dbh->prepare('DELETE FROM van_reservations WHERE id = :id');
$sth->bindParam(':id', $id, PDO::PARAM_INT);
$sth->execute();

I used to validate by using this:

Code: [Select]
$id = isset($_GET['id']) && is_numeric($_GET['id'])?(int) $_GET['id']:0;

Is there a way to only output the first, say, 30 words of a variable? I have a way to do it in mind, but seems like it's messy and not practical.

Any suggestions?

E.g:

WITHOUT LIMIT: Welcome to my store. Would you like to buy something? We have really good noodles and fishes in doodle pools.
WITH LIMIT: Welcome to my store. Would you like...

Sort of like a short preview.

code

<?php
//storecodefound.php v1.0
//purpose is to store the http refer and the code associated with the site to a db to be collected and verified by submitcode.php
$code = $_GET['code'];
$site = $_SERVER['HTTP_HOST'];


//check to see if the code already present
$connect = mysql_connect("localhost","root","") or die (mysql_error());
$check = mysql_query("SELECT code FROM hunter.codes WHERE code='$code'") or die (mysql_error());
$row = mysql_num_rows($check);
echo "result of \$row is ".$row;
echo "<br />";
if ($row = 0) {
//insert into db cause it's not there
mysql_query("INSERT INTO hunter.codes (id, code, site)
VALUES ('','$code','$site')") or die (mysql_error());
}
else {
//echo it's already here
echo "Code already found on server!";
}





?>

my question is the result of $row is infact 0 and the if statement says if $row is 0 to insert into db and instead it's given me the code is already found?

hi.
when i get into some function manual and there is a note says.
Quote

This function has been DEPRECATED as of PHP 5.3.0. Relying on this feature is highly discouraged.

.
is that meaning that after 5.3.0 version this function will not be supported?
thanks , Mor.

Hi, I've seen code like this multiple times, but I don't really know what it means.

function funcName(&$something) {
    // whatever
}

What exactly does the "&" do before the variable?
