errors converting eregi_replace into preg_replace

Question

How do I change eregi_replace in this code to preg_replace()?

This is the original code:

$title = eregi_replace('</?[a-z][a-z0-9]*[^<>]*>', '', $title );

Do I just need to overwrite eregi_replace with preg_replace or do I need to do more?

I tried this and some variations:

$title = preg_match('#<\/?[a-z][a-z0-9]*[^<>]*>#', '', $title );

When title is submited it turns into 0 and the value is lost.

Why would you change `eregi_replace` to `preg_match`? Change it from `eregi_replace` to `preg_replace`. — Sean Bright, Oct 18 '13 at 19:34
Use [preg_replace](http://php.net/manual/en/function.preg-replace.php) not `preg_match`. — The Alpha, Oct 18 '13 at 19:49
If you're doing this conversion, why not convert to using an actual HTML parser instead of doing it with regexes? — Andy Lester, Oct 18 '13 at 21:40

Here I shall make an easy answer that other users don't take time to reply:

eregi_replace() uses POSIX regex and preg_replace() uses Perl Compatible Regular Expressions PCRE, they can have differences.

But in your case with a good formed regex, it remains the same. It removes all HTML tags in the title text:

$title = eregi_replace('</?[a-z][a-z0-9]*[^<>]*>', '', $title );

$title = preg_replace('#</?[a-z][a-z0-9]*[^<>]*>#i', '', $title );
