I have a PHP array that looks like this
$alphabet= array('a','b','c')
$alphabet is a input i need a result like $result
Expected output:
$result= array(
[0]=> "a"
[1]=> "b"
[2]=> "c"
[3]=> "ab"
[4]=> "ac"
[5]=> "bc"
[6]=> "abc"
)
Note: here, I would not like sorting to use. Thanks!
Use usort and costum sort function:
$array = array("a", "bc", "bb", "aa", "cc", "bb");
function sortByValueLength($a, $b)
{
$aLength = mb_strlen($a, 'utf-8');
$bLength = mb_strlen($b, 'utf-8');
if ($aLength == $bLength) {
return strcmp($a, $b);
}
return $aLength - $bLength;
}
usort($array, 'sortByValueLength');
var_export($array);
Example result here
