Newbie asks: preg_replace

[Anon]

Im trying to get 1 instance of a string removed from a string.
(eg: blablabla, removing 1 bla)

I'm just learning php so regex is still a little out of my league.
I tried this but it didnt work:

$input='blablabla';
$todelete='bla';

preg_replace($todelete, '', $input, 1);

But didnt work, got an error.
(Warning: Delimiter must not be alphanumeric or backslash)

Thanks in advance.

The regex must be surrounded by non-alphanumeric characters, e.g.:

$todelete = '/bla/';

Ah, never thought it would be that simple 🙂

Thanks for the help, I can continue scripting now.
