<?php

// define arrays with the same keys - different key order ('4' and '@' are swapped)
$array_at = [
    '_' => '', 'Y' => '', '0' => '', '+' => '', 'X' => '', 'W' => '', '1' => '', '3' => '', '@' => '', '4' => '', '5' => '', 'P' => '', 'O' => '', 'N' => '', 'M' => '', 'L' => '', 'K' => '',
];
$array_fr = [
     '_' => '', 'Y' => '', '0' => '', '+' => '', 'X' => '', 'W' => '', '1' => '', '3' => '', '4' => '', '@' => '', '5' => '', 'P' => '', 'O' => '', 'N' => '', 'M' => '', 'L' => '', 'K' => '',
];

ksort($array_at, SORT_STRING);     // sort by key
ksort($array_fr, SORT_STRING);     // sort by key

// expects the same key at the sorted array first position
var_dump(array_slice($array_at, 0, 1));  // result: [0 => '''], but only '0' is defined as a key
var_dump(array_slice($array_fr, 0, 1));  // result: ['+' => '' ]

Output for git.master, git.master_jit, rfc.property-hooks: array(1) { ["+"]=> string(0) "" } array(1) { ["+"]=> string(0) "" }
