PHP：根据另一个不同长度的数组对数组进行排序

Question

I have two arrays of different length:

$paths_table = array("TS-0007_a.jpg", "TS-0040_a.JPG", "TS-0040_b.JPG", "TS-0040_f.JPG", "TS-0041_a.JPG", "TS-0041_b.JPG");

$order_table = array("TS-0040","TS-0007","TS-0041");

and I want to sort the first one using the second so that the output will be the array

$final_table = array("TS-0040_a.JPG", "TS-0040_b.JPG", "TS-0040_f.JPG", "TS-0007_a.jpg", TS-0041_a.JPG", "TS-0041_b.JPG")

Assuming that I'm going to use

strpos($paths_table[$i], $order_table[$j]);

to check if the string of $order_table is included in any of the $paths_table.

How can I accomplish this?

Answer 1

Preprocess the array so that each item contains an index of its prefix (that is, turn 'TS-0007_a.jpg' into [1,'TS-0007_a.jpg']):

foreach($paths_table as &$v) {
    foreach($order_table as $n => $o)
        if(strpos($v, $o) === 0) {
            $v = [$n, $v];
            break;
        }
}

sort the array:

sort($paths_table);

and remove indexes:

foreach($paths_table as &$v)
    $v = $v[1];
