# Deprecation: #85086 - GeneralUtility::arrayToLogString() {#deprecation-85086}

See [forge#85086](https://forge.typo3.org/issues/85086)

## Description {#description}

The method `GeneralUtility::arrayToLogString()`, responsible for formatting an array to a string
ready for logging or output, has been marked as deprecated.

## Impact {#impact}

Calling the method directly will trigger a PHP `E_USER_DEPRECATED` error.

## Affected Installations {#affected-installations}

Any TYPO3 installation with third-party extensions using this method.

## Migration {#migration}

For logging purposes, switch to PSR-3 compatible logging where a log-writer is taking care of outputting / storing
this information properly.

For other purposes, like CLI-command output, it is recommended to implement this functionality directly in the
corresponding CLI command.
