Sort words by length

Is there a way to order the following words by length?

Thanks.

 

If you can put them into an array, you could sort using usort.

You can put them into an array using the following:

$string = 'Bannana
Apple
Orange
Pear
Pea';

$array = explode("\n", $string);
?>

PHP:

 

<?php

$string = 'Banana
Apple
Orange
Pear
Pea';

$array = explode("\n", $string); /* Split it up */
usort($array, create_function('$a, $b', 'return strlen($a)-strlen($b);')); /* Largest -> smallest */
$string = implode("\n", $array); /* Put it back together again */

echo $string;
/* Output */

Thanks for the replies, I've managed it using:

			function cmp( $a, $b ) {
				return strlen($a)-strlen($b) ;
			}
			
			
                        $string = "pear
                                      bannana
                                      pea";	
			$a = explode("\n", $string);
			usort($a, "cmp");
			
			foreach ($a as $key => $value) {
			
				
                        echo "$value<br />";

				
			}

Just a FYI

usort($array, create_function('$a, $b', 'return strlen($a)-strlen($b);'));

PHP:

does exactly the same as all of

function cmp( $a, $b ) {
                return strlen($a)-strlen($b) ;
            }
            
            usort($a, "cmp");
