# Merge ViewHelper `<f:merge>`

The MergeViewHelper merges two arrays into one, optionally recursively.

It works similar to the PHP functions array_merge() and array_merge_recursive(),
depending on the value of the "recursive" argument.

Go to the source code of this ViewHelper: [MergeViewHelper.php (GitHub)](https://github.com/TYPO3/Fluid/blob/main/src/ViewHelpers/MergeViewHelper.php).
