file_put_contents should support LOCK_NB just like it supports LOCK_EX.

luckily file_put_contents does not currently support any flags with the same value as LOCK_NB( LOCK_NB is 4 and FILE_USE_INCLUDE_PATH is 1 and FILE_APPEND is 8)

Test script:

Expected result:
bool(false) and perhaps some error about being unable to lock.

Actual result:
script hangs indefinitely, because file_put_contents doesn't understand LOCK_NB
