Question: How to remove all characters exept numbers from a string using PHP?
Answer:
This is really easy, we will make use of the preg_replace PHP Function which is 100% compatible with PHP 5.3
Example:
$string = 'This is my phone number: +28 (0)212 1234!!! '
$numberString = preg_replace('[\D]', '', $string);
echo $numberString; //Will output 2802121234
This is a good way to format phone numbers etc.
The regular expression character \D means to match a character that's not a digit
