TYPO3 Core

This happens when some configuration values are objects.
By example, a Closure for a hook...

The PHP warning is also issued if the search is done with regexMode on.

In "typo3/sysext/lowlevel/Classes/Utility/ArrayBrowser.php":

            if ($this->regexMode) {
                if (
                    preg_match('/' . $searchString . '/', $keyArr[$key])
                    || $this->searchKeysToo && preg_match('/' . $searchString . '/', $key)
                ) {
                    $this->searchKeys[$depth] = 1;
                }
            } else {
                if (
                    !$deeper && stristr($keyArr[$key], $searchString)
                    || $this->searchKeysToo && stristr($key, $searchString)
                ) {
                    $this->searchKeys[$depth] = 1;
                }
            }

... should be replaced by:

            if ($this->regexMode) {
                if (
                    is_scalar($keyArr[$key]) && preg_match('/' . $searchString . '/', $keyArr[$key])
                    || $this->searchKeysToo && preg_match('/' . $searchString . '/', $key)
                ) {
                    $this->searchKeys[$depth] = 1;
                }
            } else {
                if (
                    is_scalar($keyArr[$key]) && stristr($keyArr[$key], $searchString)
                    || $this->searchKeysToo && stristr($key, $searchString)
                ) {
                    $this->searchKeys[$depth] = 1;
                }
            }
