[return string after and including $needle in the string $haystack]

Amazing guys thanks a lot, I'm trying to learn as I code and am just working out what everything is, means, and references. I hate being a noob!

[return string after and including $needle in the string $haystack]

Hello all,

 

I'm trying to change the end of a javascript call based on the end of the url string. The common part of all the url strings is sobi2Id=, I'm trying to do this with strstr but am having no luck. I'm new to php so my syntax knowledge is terrible!

 

at the moment i've got

 

<?php

		    	$url = $_SERVER['REQUEST_URI'];

	    	$tag = strstr ($url, 'sobi2Id=');

		    	echo $tag; 
?>

 

but this returns an unexpected T_STRING, expecting ',' or ';'

 

Can anyone debug this? I may well be being really silly!

[Hide a div based on url]

<?php 

		   if (strpos($_SERVER['REQUEST_URI'], 'foo') == false) {
    		   echo '<div id="stuffdiv">stuff</div>';}

[Hide a div based on url]

Hi all,

 

Relitively new to PHP but am trying to code a site that dynamically creates urls using Joomla CMS. Basically I'd like a div to show on pages' url starts /component/.... but hide it if not. The urls of the pages on which the div is to be hidden start /index.php?.

 

I've tried

 

<?php 

		   if (strpos($_SERVER['REQUEST_URI'], 'component') > 0) {
		   echo '<div id=\"stuffdiv\">stuff</script></div>';}

	?>

 

only issue is... its always fasle hence the div never shows. If i replace > with >= its always true, and appears on all pages, even those not containing 'component'...

 

Can someone tell me if this should work or if Im being really stupid?

 

Thanks in advance! Tom
