Stripping text from a variable

[netfrugal]

I can't remember the php function

I have this date: 2007-06-01

I want to strip out the "-" so it will show: 20070601

Anyone remember the function that does that?

[man]str_replace[/man]

And in case you aren't sure what the separators might be:

// replace anything that is not a decimal digit:
$string = preg_replace('/\D/', '', $string);
