Haystack-Needle-Sheet

Surely every PHP developer has come across the PHP Haystack-Needle-Phenomenon: Mostly the parameter order is $haystack, $needle but in some cases it's $needle, $haystack for no apparent reason. Trying to find regularities I found out that it's only the array functions that use needle, haystack instead of haystack, needle - assuming I didn't forget any functions. For that reason I created a Haystack-Needle-Sheet, which shows you which function uses haystack, needle and which one needle, haystack.
If you should come across functions that are missing on this list, please let me know.
