[RESOLVED] Change line from preg_replace to preg_replace_callback

[halojoy]

I have tried everything but only get error.
I have this line and want to use preg_replace_callback.

echo preg_replace('!([^0]{1})!e', "strtoupper('\\1').'<br />'", $v[1]);

Thanks very much if you can help me 🙂

preg_replace e-modifier is deprecated.

There is an example in the manual that's pretty close to what you're doing, which would probably translate to something like:

echo preg_replace_callback(
	'!([^0]{1})!e',
	function ($matches)
	{
		return strtoupper($matches[1]) . '<br />';
	},
	$v[1]
);

I actually got it working!
Thanks NogDog 🙂

This is the code that works for me:

echo preg_replace_callback('/(^|_)([a-z])/',
    function($matches) {
        return strtoupper($matches[1]) . '<br />';
    },
    $v[1]);
