Welcome to the Merge Sort in Php page! Here, you'll find the source code for this program as well as a description of how the program works.

```
<?php
function merge_sort($my_array)
{
if (count($my_array) == 1) {
return $my_array;
}
$mid = count($my_array) / 2;
$left = array_slice($my_array, 0, $mid);
$right = array_slice($my_array, $mid);
$left = merge_sort($left);
$right = merge_sort($right);
return merge($left, $right);
}
function merge($left, $right)
{
$res = array();
while (count($left) > 0 && count($right) > 0) {
if ($left[0] > $right[0]) {
$res[] = $right[0];
$right = array_slice($right, 1);
} else {
$res[] = $left[0];
$left = array_slice($left, 1);
}
}
while (count($left) > 0) {
$res[] = $left[0];
$left = array_slice($left, 1);
}
while (count($right) > 0) {
$res[] = $right[0];
$right = array_slice($right, 1);
}
return $res;
}
if (empty($argv[1])) {
exit('Usage: please provide a list of at least two integers to sort in the format "1, 2, 3, 4, 5"');
}
$test_array = array_map('intval', explode(',', $argv[1]));
$array_size = count($test_array);
if ($array_size <= 1) {
exit('Usage: please provide a list of at least two integers to sort in the format "1, 2, 3, 4, 5"');
}
echo implode(', ', merge_sort($test_array)) . "\n";
```
