No need for RegEx

 

<?php 

$str = '"basePath":"\/"';
$toAdd = 'http://mypage.com';

$final = substr($str,0,12) . $toAdd . substr($str,12);

echo $final;

?>

i am reading an html file...

 

i do not have the string.. i am trying to find it...

 

so the string i am looking for is

 

"basePath":"\/"

 

so i need to find the string in the page and change to

 

"basePath":"www.mypage.com\/"

 

ie.  here is part of the full string i am searching

<!--//--><![CDATA[//><!--

jQuery.extend(Drupal.settings, {"basePath":"\/","pathPrefix":"","ajaxPageState":{"theme":"base","theme_token":"5XoHI1_0PUfE

User strpos to get the offset of "basePath":"

 

Insert that offset into substr

 

Et voila
