ordinamento array

[Albertorrr]

Forse intende una cosa del genere:

$b = '11|a'; 


echo '<pre>';
$arr = array('10|a','12|a','13|a','13|a','14|a');


print_r($arr);
foreach($arr as $key => $a) {
    $_new = (int) $b;
    $_actual = (int)$a;
    
    if($_new == $_actual) {
        array_splice($arr, $key, 0, array($b));
        break;
    } else {
        $arr[] = $b;
        break;
    }
}


print_r($arr);
