Based on (2) saved test runs, The test labeled "stream_socket_client()" was (on average) the faster by 0.0066 seconds, (0.815% faster)
The stream_socket_client() test took 0.8059 seconds.
The fsockopen() test took 0.8125 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 202,047 loops for a total of 4,040,930 runs.
- Line execution difference (0.000002) milliseconds.
- Avg difference (0.000) milliseconds per 202,047 loops.
- Total difference 6.62 milliseconds for 4,040,930 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.
Code
The first test, "stream_socket_client()", was:
$fp = stream_socket_client('tcp://127.0.0.1:80', $errno, $error);
fclose($fp);
The second test, "fsockopen()", was:
$fp = fsockopen('127.0.0.1', 80, $errno, $error);
fclose($fp);
