Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 284,022 loops for a total of 5,680,440 runs.
- Line execution difference (0.000011) milliseconds.
- Avg difference (0.000) milliseconds per 284,022 loops.
- Total difference 59.65 milliseconds for 5,680,440 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, "addslashes()", was:
$GLOBALS['dummy2'] = addslashes($GLOBALS['dummy']);
The second test, "mysql_escape_string()", was:
$GLOBALS['dummy2'] = mysql_real_escape_string($GLOBALS['dummy']);
