php Regex help

Hi All.

I am having problems with what seems to be a straightforward regex and will appreciate a few eyes on the issue and tips where I have screwed up.

Basically, I am trying to add to the head section of a html page.

The html has already been successfully loaded in $htmlData and the additional data to be added is in $extraHeadData.

Can anyone kindly point me to why the regex below fails to match?

$htmlFinal = preg_replace('#<\/head>#i', $extraHeadData . "\n</head>", $htmlData);

Thanks

Curiously, it seems to work fine :

PHP Code:


			
<?php



ini_set('display_errors', '1');

error_reporting(E_ALL);



$htmlData = '<head>test</head>';

$extraHeadData = 'extra';

$htmlFinal = preg_replace('#<\/head>#i', $extraHeadData . "\n</head>", $htmlData);



echo $htmlFinal; // <head>testextra\n</head>

This does indeed. Error was elsewhere.

I was doing the equivalent of ...

PHP Code:


			
$htmlData = '<head>test</head>'; 

$extraHeadData = 'extra'; 

$htmlFinal = preg_replace('#<\/head>#i', $extraHeadData . "\n</head>", $htmlData); 

echo $htmlData; // instead of $htmlFinal
