[PHP] Replacing text on page, but not in img tags
Lets say im trying to replace every occurance of 'hello' with 'bhi/b'. heres a sample page html hello there! /html This would simply change to html bhi/b there! /html but what if it had an img? html hello there! img src=hello.jpg alt=well hello there /html It would then be, html bhi/b there! img src=bhi/b.jpg alt=well bhi/b there /html It would then be completely jacked up. Not only would it do the wrong img, but the tag in general would be screwed be cause of the bold tag. So what can I do? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Here's something that's probably close to what you want. Something else
you need to worry about besides img tags is what if the word hello
appears in a a tag? within Javascript?
This will match anything outside of tags, at least, and then add in the
strong tags around hello.
function callback($match)
{ return str_replace('hello','stronghello/strong',$match[0]); }
$new_str = preg_replace_callback('/([^]+)/','callback',$str);
