Validate that a string starts with specified numbers then a certain number of digits

$output = preg_replace( '/[^0-9]/', '', $string );

How can I change the above line to only accept 11 digit long numbers that must start with either 01, 02, 03, 05, 07 or 08, but NOT 04, 06, 09?

Try this:

^0[1-3578]\d{9}$

Regular expression visualization

0-Zero [^469]-Number except 469 \d-Any Number

Try this one:

$output = preg_replace( '/^0[1-3578]\d{9}/', '', $string );

\d{9} means 9 digits as you have already 2 digits back.
