str_replace(), only X times?

[Michdd]

Is it possible to make str_replace only replace the first X occurrences?

Find out - str_replace

I've already read that. I know with the function itself it isn't possible.. What I meant was.. what would be a good way to use str_replace, but set it up so that it only replaces the first X occurrences

Sorry, I meant substr_replace. You can use that, but I would use combo explode and implode.

Or if you don't mind starting the RegEx engine, preg_replace() has a limit parameter.

function str_replace_count($search, $replace, $subject, $limit)
{
for ($i = 0, $replaceLength = strlen($replace); $i < $limit && ($pos = strpos($subject, $search)) !== false; $i++) {
	$subject = substr_replace($subject, $replace, $pos, $replaceLength);
}

return $subject;
}

$string = 'foo foo foo foo foo foo foo';

echo str_replace_count('foo', 'bar', $string, 3); // bar bar bar foo foo foo foo
