PHP - Replacing ereg with preg

Question

I am trying to remove deprecated code from a site. Can anyone tell me a preliminary equivalent

ereg_replace("<b>","<strong>",$content);

Thank.

PCRE is the equivalent of ERE regex:

preg_match("/<b>/", "<strong>", $content)

But as Jacco already pointed out, you don't need a regex at all as you want to replace a constant value.

There seems to be no need for regular expressions.

simple str_replace will do:

$cleaned = str_replace  ('<b>', '<strong>', $unCleaned);

If you need more complex replacements like attribute validation, you can do:

$cleaned = preg_replace('/<b(\s[^>]*)?>/', '<strong\\1>', $unCleaned);

But this is by no means ideal; something like <div title="foo->bar"></div>

will break the regex.
