1.2.276. Could Be array_combine()¶
This rule suggests using the native function array_combine() to merge two arrays into a hash. array_combine() takes the keys and the values from two distinct arrays, and merge them into one.
<?php
$keys = [1, 2, 3];
$values = ['a', 'b', 'c'];
$destination = [];
foreach($keys as $k => $v) {
$destination[$v] = $values[$k];
}
$destination = [1 => 'a', 2 => 'b', 3 => 'c'];
$destination = array_combine($keys, $values);
?>
