LuaSandbox::getProfilerFunctionReport — Fetch profiler data
For a profiling instance previously started by LuaSandbox::enableProfiler(), get a report of the cost of each function.
The measurement unit used for the cost is determined by the $units parameter:
LuaSandbox::SAMPLESMeasure in number of samples.
LuaSandbox::SECONDSMeasure in seconds of CPU time.
LuaSandbox::PERCENTMeasure percentage of CPU time.
unitsMeasurement unit constant.
Returns profiler measurements, sorted in descending order, as an associative array. Keys are the Lua function names (with source file and line defined in angle brackets), values are the measurements as int or float.
Hinweis:
On Windows, this function always returns an empty array. On operating systems that do not support
CLOCK_THREAD_CPUTIME_ID, such as FreeBSD and Mac OS X, this function will report the elapsed wall-clock time, not CPU time.
Beispiel #1 Profiling Lua code
<?php
// create a new LuaSandbox
$sandbox = new LuaSandbox();
// Start the profiler
$sandbox->enableProfiler( 0.01 );
// ... Execute some Lua code here ...
// Fetch the profiler data
$data = $sandbox->getProfilerFunctionReport();
?>
