1.2.47. Array_Fill() With Objects¶
array_fill() fills an array with identical objects, not copies nor clones. This means that all the filled objects are a reference to the same object. Changing one of them will change any of them.
Make sure this is the intended effect in the code.
This applies to array_pad() too. It doesn’t apply to array_fill_keys(), as objects will be cast to a string before usage in this case.
<?php
$x = new StdClass();
$array = array_fill(0, 10, $x);
$array[3]->y = "Set in object #3";
// displays "Set in object #3"
echo $array[5]->y;
?>
1.2.47.1. Suggestions¶
Use a loop to fill in the array with cloned() objects.
