Install xhprof
cd xhprof/extension/ phpize ./configure makemake install
Then add
extension=xhprof.so
execution
php -m | grep xhprof
to /etc/php.ini according to the situation and you can see Output, indicating that the php extension is installed successfully, and then restart Apache or php-fpm
Run
You can directly run the example in the example directory in the file cloned from github
The output is as follows
Array ( [main()] => Array ( [ct] => 1 [wt] => 9 )) ---------------Assuming you have set up the http based UI for XHProf at some address, you can view run at http://<xhprof-ui-address>/index.php?run=592567308784c&source=xhprof_foo ---------------
Then copy the ?run=592567308784c&source=xhprof_foo
Visit
xhprof_html/index.php?run=592567308784c&source=xhprof_foo
You can see the output

Error reporting
failed to execute cmd:" dot -Tpng". stderr:sh: dot:command not found。
//解决方案yum install graphviz
Adapt to changes
For example, if you want to test your own project, such as a framework Performance analysis.
Copy the two files under xhprof_lib/utils/
xhprof_lib.php and xhprof_runs.php to the same directory as the entry file, and then add
// start profiling xhprof_enable();
// stop profiler $xhprof_data = xhprof_disable(); // display raw xhprof data for the profiler run print_r($xhprof_data); include_once "xhprof_lib.php"; include_once "xhprof_runs.php"; // save raw data for this profiler run using default // implementation of iXHProfRuns. $xhprof_runs = new XHProfRuns_Default(); // save the run under a namespace "xhprof_foo" $run_id = $xhprof_runs->save_run($xhprof_data, "xhprof_foo"); echo "---------------\n". "Assuming you have set up the http based UI for \n". "XHProf at some address, you can view run at \n". "http://<xhprof-ui-address>/index.php?run=$run_id&source=xhprof_foo\n". "---------------\n";

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
