cd php-profiler-extension
phpize
./configure

sudo apt-get install -y graphviz

Set alias

alias tk=toolkit

tideways toolkit

Code Buried Point

Add

if (extension_loaded('tideways_xhprof')) {
    tideways_xhprof_enable(TIDEWAYS_XHPROF_FLAGS_CPU | TIDEWAYS_XHPROF_FLAGS_MEMORY);
}
// 你的代码
application();
if (extension_loaded('tideways_xhprof')) {
    $data = tideways_xhprof_disable();
    file_put_contents(
        sprintf('%s/app.xhprof', '/path/to'),
        json_encode($data)
    );
}

to the program entrance to execute the code , and then /path/to/app.xphrof

Performance Analysis

tk analyze-xhprof /path/to/app.xphrof

The default performance analysis indicator is wt_excl , other indicators include

1.wt call duration, including sub-functions

2.excl_wt call duration, excluding sub-functions

3.cpu CPU call duration, including Subfunction

4.excl_cpu CPU call duration, excluding subfunction

5.memory memory consumption (bytes), including subfunction

6.excl_memory memory consumption ( Bytes), excluding sub-functions

7.io io duration, including sub-functions

8.excl_io io duration, excluding sub-functions

Generation performance The indicators displayed in the bottleneck chart

tk generate-xhprof-graphviz /path/to/app.xhprof
dot -Tpng callgraph.dot > callgraph.png
