Опис

array_replace(array $array, array ...$replacements): array

array_replace() creates a new array and assigns items into it for each key in each of the provided arrays. If a key appears in multiple input arrays, the value from the right-most input array will be used.

array_replace() does not process elements items recursively, it replaces the entire value for each key when it does a replacement.

Параметри

array

The array in which elements are replaced.

replacements

Arrays from which elements will be extracted. Values from later arrays overwrite the previous values.

Значення, що повертаються
