That's the point of recursion... to recursively call oneself!

Not sure why you're getting that error since it appears to be well
defined above... unless xxxxx.php is not the same file in which
mkdir_recursive() ha sbeen defined. I'll wager it's not... in which case
you need to ensure the file that contains the mkdir_recursive() function
declaration is included into xxxxx.php. BTW, FWIW, I wouldn't call the
above code good quality since it obfuscates its intent by using ||
hackishness. It's succinct but less obvious.
Cheers,
