Historical Results

Based on (6) saved test runs, The test labeled "fsockopen()" was (on average) the faster by 0.015 seconds, (1.942% faster)

fsockopen() 100%
stream_socket_client() 98.058%

The fsockopen() test took 0.7566 seconds.
The stream_socket_client() test took 0.7716 seconds.


Each test case ran 20 random code order iterations consisting of 139,560 loops for a total of 2,791,197 runs.

  • Line execution difference (0.000005) milliseconds.
  • Avg difference (0.000) milliseconds per 139,560 loops.
  • Total difference 14.98 milliseconds for 2,791,197 loops

The iteration variablity for Code 1 was (0.0000) milliseconds and Code 2 was (0.0000) 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);
