Sch?nen guten Morgen M. Bauer,
siehe diese Information zur split() function:
What is the replacement for split in PHP?
split() is deprecated as of PHP 5.3. 0. preg_split() is the suggested alternative to this function. If you don’t require the power of regular expressions, it is faster to use explode(), which doesn’t incur the overhead of the regular expression engine.
Hoffe dies hilft.
