# Deprecation: #86389 - GeneralUtility::\_GETset() and TSFE->mergingWithGetVars() {#deprecation-86389}

See [forge#86389](https://forge.typo3.org/issues/86389)

## Description {#description}

Two methods related to setting global `$_GET` parameters have been marked as deprecated:

-   `TYPO3\CMS\Core\Utility\GeneralUtility::_GETset()`
-   `TYPO3\CMS\Frontend\Controller\TypoScriptFrontendController->mergingWithGetVars()`

The two methods are wrappers to set the `$_GET` properties, however, this concept has been superseded
by using the PSR-7 request object within PSR-15 middlewares to replace the variables.

## Impact {#impact}

Calling any of the two methods within PHP will trigger a PHP `E_USER_DEPRECATED` error.

## Affected Installations {#affected-installations}

Any installation making use of these methods within a TYPO3 extension, e.g. RealURL.

## Migration {#migration}

Implement a custom PSR-15 middleware to update the PSR-7 request object, and to manually set `$_GET` on top,
as long as TYPO3 still supports `GeneralUtility::_GP()`, although these methods will vanish in the near future.

Relying on the request object, and using PSR-15 middlewares to manipulate request parameters is more future-proof
for extensions and TYPO3 sites.
