lets say you have a string in a form and you want to delete all the numbers from the value of that string. well, today, i will show you..

you can use this function

CODE:
<?php
	# FUNCTION BY WWW.WEBUNE.COM
	function remove_numbers($string) {
  		$vowels = array("1", "2", "3", "4", "5", "6", "7", "8", "9", "0", " ");
  		$string = str_replace($vowels, '', $string);
  		return $string;
  	}
	$string='This string will have all numbers removed - 213 555 3930';
	echo remove_numbers($string);
?>


this will remove all the numbers from the variable string

OUTPUT:
