Breaking: #102151 - XML prologue always added in flexArray2Xml()¶

Description¶

The second argument $addPrologue = false on TYPO3\CMS\Core\Configuration\FlexForm\FlexFormTools->flexArray2Xml() has been dropped: When imploding a flex form array to an XML string using this method, the "XML prologue" is always added.

Impact¶

This should have no impact for consumers of this method. The counterpart method TYPO3\CMS\Core\Utility\GeneralUtility::xml2array() happily deals with this.

Affected installations¶

Instances with extensions using FlexFormTools->flexArray2Xml() can drop the second argument. The extension scanner will find usages with a weak match.

Since this is a detail method of the TYPO3 core flex form handling, not often handled by extensions themselves, few instances will be affected in the first place.

Migration¶

No data migration needed, PHP consumers should drop the second argument when calling the method.
