The test labeled "fsockopen()" was the faster by 0.0199 seconds, (3.143% faster)

fsockopen() 100%
stream_socket_client() 96.857%

The fsockopen() test took 0.6138 seconds.
The stream_socket_client() test took 0.6337 seconds.


Each test case ran 20 random code order iterations consisting of 145,952 loops for a total of 2,919,040 runs.

  • Line execution difference (0.000007) milliseconds.
  • Avg difference (0.996) milliseconds per 145,952 loops.
  • Total difference 19.92 milliseconds for 2,919,040 loops

The iteration variablity for Code 1 was (5.8619) milliseconds and Code 2 was (5.7295) 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);
