(PHP) Speed Test: array_push vs $array[] - mthorn

Took 0.164692 seconds for array[] Took 0.395778 seconds for array_push As you can see array_push is more than twice as slow. Here are the reasons. Array_push is a function call, Function calls are always slower. Array_push takes mixed parameters, parameter checking is always slower. Also array[] just looks cleaner and is less to type. Tips: Always pre-intialize your variables and don't use mixed types even though you can.

strcmp with matching strings took 0.207852 seconds strcmp with non-matching strings took 0.215276 seconds === with matching strings took 0.067122 seconds === with non-matching strings took 0.057305 seconds === is the clear winner. Function calls are always slower than operators. This was with PHP5, may be different for earlier versions. Not sure about the memory impact but I assume it's less since the strings do not have to be copied for the function call.
