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:
This string will have all numbers removed -

you can also remove text instead of numbers, just switch the numbers in
$vowels = array("y", "z", "3", "4", "4", "3", "z", "y", "x", "x", " "); to
$vowels = array("a", "b", "c", "d", "e", f", "g"," "); etc.

note:
if you wan't big letters for this function don't forget that you will need to verify this to the function like this:
$vowels = array("a", "b", "c", "d", "e", f", "g","a","b","c", "d" " "); etc.

great function!

why not use regular expressions? for example:
$string = preg_replace('/[^a-z]/i', '', $string);
will remove everything except a-z (and a-z of course since /i = case insensitive).

because it does not work.. did your try it?

preg_replace('/[^0-9]/i', '', $string) does the oppostite in this insatnce it will retain the numerics as it will retain the alpha characters if you change it to preg_replace('/[^a-z]/i', '', $string) where it will throw away all other characters except the alpha characters.
