Use usort() in conjunction with a user defined function that compares the
length of
both strings using strlen(). If brevity at the (possible) expense of clarity is
your thing, you can even use create_function() as your

With a user defined sorting function something like this
?php
function cmp($a, $b){
$x = strlen($a);
$y = strlen($b);
if ($x == $y) {
return 0;
}
return

How about iterating though the strings and putting string values and
lengths in an array:
[begin untested code]
$strings = array('i','am','who');
$string_count = array();
foreach ($strings as $string) {
$string_count['value'][] = $string;
$string_count['length'][] = strlen($string);
}
Is it an associative array? That is, are you assigning values like this:
Method 1:
$arr[] = some text string;
or
$arr = array(some text string,some text string too);
or like this...
Method 2:
$arr[value1] = some text string;
or
$arr1 = array(value1=some text string,value2=some text string

You write a function that compares two strings (A and B), and returns
0 if len(A) == len(B), -1 if len(A) len(B) or +1 if len(A) len(B).
function compare_by_length ($a, $b)
{
$la = strlen
8 matches
