(PHP 5, PHP 7, PHP 8)
array_combine — Creates an array by using one array for keys and another for its values
array_combine(array $keys, array $values): array
Creates an array by using the values from the keys array as keys and the values from the values array as the corresponding values.
Returns the combined array.
As of PHP 8.0.0, a ValueError is thrown if the number of elements in keys and values does not match. Prior to PHP 8.0.0, a E_WARNING was emitted instead.
| Version | Description |
|---|---|
| 8.0.0 | array_combine() will now throw a ValueError if the number of elements for each array is not equal; previously this function returned false instead. |
