LuaSandbox::getProfilerFunctionReport

LuaSandbox::getProfilerFunctionReport — Fetch profiler data

说明

public LuaSandbox::getProfilerFunctionReport ([ int $units = LuaSandbox::SECONDS ] ) : array

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::SAMPLES

Measure in number of samples.

LuaSandbox::SECONDS

Measure in seconds of CPU time.

LuaSandbox::PERCENT

Measure percentage of CPU time.

参数

units

Measurement unit constant.

返回值

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 integer or float.

Note:

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.

范例

Example #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();

?>
