Result: Discarded

The test labeled "stream_socket_client()" was the faster by 0.0513 seconds, (4.443% faster)

stream_socket_client() 100%
fsockopen() 95.557%

The stream_socket_client() test took 1.1035 seconds.
The fsockopen() test took 1.1548 seconds.


Each test case ran 20 random code order iterations consisting of 278,367 loops for a total of 5,567,340 runs.

  • Line execution difference (0.000009) milliseconds.
  • Avg difference (2.565) milliseconds per 278,367 loops.
  • Total difference 51.31 milliseconds for 5,567,340 loops

The iteration variablity for Code 1 was (2.2799) milliseconds and Code 2 was (5.0311) 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);
