# Deprecation: #79316 - Deprecate ArrayUtility::inArray()

See [forge#79316](https://forge.typo3.org/issues/79316)

## Description

Deprecate ArrayUtility::inArray()

## Impact

Calling `ArrayUtility::inArray()` method will trigger a deprecation log entry. Code using this method will work until it is removed in TYPO3 v9.

## Affected Installations

Any installation using the mentioned method `ArrayUtility::inArray()`.

## Migration

Use the native `in_array()` function of PHP. It is strongly recommended to ensure the same type is used
everywhere and the 3rd parameter of `in_array()` is set to `true` to activate the type check.
