Result: Discarded

The test labeled "stream_socket_client()" was the faster by 0.0168 seconds, (1.949% faster)

stream_socket_client() 100%
fsockopen() 98.051%

The stream_socket_client() test took 0.8458 seconds.
The fsockopen() test took 0.8627 seconds.


Each test case ran 20 random code order iterations consisting of 210,663 loops for a total of 4,213,260 runs.

  • Line execution difference (0.000004) milliseconds.
  • Avg difference (0.841) milliseconds per 210,663 loops.
  • Total difference 16.81 milliseconds for 4,213,260 loops

The iteration variablity for Code 1 was (1.9091) milliseconds and Code 2 was (2.9568) milliseconds. The lower and the closer together there values are the more accurate the results are.


The first test, "stream_socket_client()", was:

$fp = stream_socket_client('tcp://', $errno, $error);

The second test, "fsockopen()", was:

$fp = fsockopen('', 80, $errno, $error);
