In PHP, associative arrays are ordered since version 7.0.0. Prior to that version, the order of elements in an associative array was undefined and may change between different PHP versions or runs.
Starting from PHP 7.0.0, the order of elements in associative arrays is maintained in the order they are added. This means that when elements are added to the array, they are appended to the end of the array in the order they are added. When iterating over the array using a loop, the elements will be returned in the order they were added. However, it's important to note that the order may still change if elements are deleted or rearranged using functions such as unset () or array_splice ().
