Answer 1

Use the following regex substitution:

$result = preg_replace("/^\+\d+-/", "", $sPhoneNumber);

It will remove 1+ digits and a - after it from the start of a string.

Using this solution, you will avoid changing strings that do not start with + followed with digits.

Instead of \d+ you may specify the country codes you need to remove. Say, you need to remove 22 and 48 codes:

$result = preg_replace("/^\+(?:48|22)-/", "", $sPhoneNumber);
