String replace only first character in Laravel View

Question

I'm using Laravel for my website.

In my view, I received a string variable from controller like this "01230456", I want to replace only first character "0" to "ABC", not the second "0" in string.

I tried preg_replace('\0\', 'ABC', $string, 1), but it replaced all "0" character in my string.

How should I fix this?

Thank you!

Have you tried this

preg_replace('/0/', 'ABC', $string, 1)

or you can use substr

$sub = substr($string, 1);
$new = 'ABC' . $sub;
