To remove all the special character from a string
For example
Lets strip all the characters from telephone number
<?php $tel = +91 9876-453-210 $tel = preg_replace('/[^a-zA-Z0-9]/','',$tel); echo $tel; ?>
it will remove all the special characters from the string including hyphens, spaces, dots parenthesis etc.
String | Output preg_replace Expression : /[^a-zA-Z0-9]/ |
---|---|
+91 9875.654.321 | 91987654321 |
