7 tools to analyze and parse PHP code
PHP has become one of the most popular programming languages nowadays, but many PHP programmers are troubled by not finding suitable tools to help them analyze and parse PHP code. Today, the editor will introduce to you some very good tools to help programmers improve their work efficiency. Let’s take a look!
PHP Parser
PHP-Parser is a PHP parser written in PHP (supports PHP 5.4 and earlier). This special parser is very suitable for static code analysis. The purpose of this tool is to simplify static code analysis and manipulation, and it enables programmers to programmatically process the code of any application.
PHPSandbox
PHPSandbox is a way to run PHP as a standalone process. It provides programmers with a kind of protection for peripheral scripts, such as errors, crashes, slow-running scripts, or scripts that are not suitable for running in the code, can be run as independent processes.
PHP Mess Detector
PHPMD is a tool that can detect some potential problems in PHP source code. For example:
- Possible Bug
- Sub-optimal code
- Overly complex syntax
- Never used parameters, methods, attributes
PHPCPD
PHPCPD is a tool that looks for similar patterns in code. Use it to identify where code has been copied or pasted in a code base. This is a very useful tool during the regular build process and will help programmers analyze the code to avoid repeated function calls in the code base.
PHPCcheckstyle
PHPCcheckstyle is a tool to help PHP programmers check code and report errors, running on PHP 5.0 and higher. By calling PHPCheckstyle through an SVN hook script, you can force the code to comply with preset coding standards (such as the PEAR coding standard), which helps improve the overall quality of the code in multi-person collaboration projects.
Ubench
Ubench is a development library used to evaluate PHP code execution time and memory usage efficiency. How to use:
<ol class="dp-j"><li class="alt"><span><span>require_once </span><span class="string">'src/Ubench.<span id="1_nwp" style="width: auto; height: auto; float: none;"><a id="1_nwl" href="http://cpro.baidu.com/cpro/ui/uijs.php?app_id=0&c=news&cf=1001&ch=0&di=128&fv=11&is_app=0&jk=f35ff87300cda873&k=php&k0=php&kdi0=0&luki=8&n=10&p=baidu&q=06011078_cpr&rb=0&rs=1&seller_id=1&sid=73a8cd0073f85ff3&ssp2=1&stid=0&t=tpclicked3_hc&tu=u1922429&u=http%3A%2F%2Fwww%2Eadmin10000%2Ecom%2Fdocument%2F6257%2Ehtml&urlid=0" target="_blank" mpid="1" style="text-decoration: none;"><span style="color:#0000ff;font-size:14px;width:auto;height:auto;float:none;">php</span></a></span>'</span><span>; </span></span></li><li><span> </span></li><li class="alt"><span>$bench = <span class="keyword">new</span><span> Ubench; </span></span></li><li><span> </span></li><li class="alt"><span>$bench->start(); </span></li><li><span> </span></li><li class="alt"><span><span class="comment">// Execute some code</span><span> </span></span></li><li><span> </span></li><li class="alt"><span>$bench->end(); </span></li><li><span> </span></li><li class="alt"><span><span class="comment">// Get elapsed time and <span id="2_nwp" style="width: auto; height: auto; float: none;"><a id="2_nwl" href="http://cpro.baidu.com/cpro/ui/uijs.php?app_id=0&c=news&cf=1001&ch=0&di=128&fv=11&is_app=0&jk=f35ff87300cda873&k=memory&k0=memory&kdi0=0&luki=4&n=10&p=baidu&q=06011078_cpr&rb=0&rs=1&seller_id=1&sid=73a8cd0073f85ff3&ssp2=1&stid=0&t=tpclicked3_hc&tu=u1922429&u=http%3A%2F%2Fwww%2Eadmin10000%2Ecom%2Fdocument%2F6257%2Ehtml&urlid=0" target="_blank" mpid="2" style="text-decoration: none;"><span style="color:#0000ff;font-size:14px;width:auto;height:auto;float:none;">memory</span></a></span></span><span> </span></span></li><li><span> </span></li><li class="alt"><span>echo $bench->getTime(); <span class="comment">// 156ms or 1.123s</span><span> </span></span></li><li><span> </span></li><li class="alt"><span>echo $bench->getTime(<span class="keyword">true</span><span>); </span><span class="comment">// elapsed microtime in float</span><span> </span></span></li><li><span> </span></li><li class="alt"><span>echo $bench->getTime(<span class="keyword">false</span><span>, </span><span class="string">'%d%s'</span><span>); </span><span class="comment">// 156ms or 1s</span><span> </span></span></li><li><span> </span></li><li class="alt"><span>echo $bench->getMemoryPeak(); <span class="comment">// 152B or 90.00Kb or 15.23Mb</span><span> </span></span></li><li><span> </span></li><li class="alt"><span>echo $bench->getMemoryPeak(<span class="keyword">true</span><span>); </span><span class="comment">// memory <span id="3_nwp" style="width: auto; height: auto; float: none;"><a id="3_nwl" href="http://cpro.baidu.com/cpro/ui/uijs.php?app_id=0&c=news&cf=1001&ch=0&di=128&fv=11&is_app=0&jk=f35ff87300cda873&k=peak&k0=peak&kdi0=0&luki=3&n=10&p=baidu&q=06011078_cpr&rb=0&rs=1&seller_id=1&sid=73a8cd0073f85ff3&ssp2=1&stid=0&t=tpclicked3_hc&tu=u1922429&u=http%3A%2F%2Fwww%2Eadmin10000%2Ecom%2Fdocument%2F6257%2Ehtml&urlid=0" target="_blank" mpid="3" style="text-decoration: none;"><span style="color:#0000ff;font-size:14px;width:auto;height:auto;float:none;">peak</span></a></span> in bytes</span><span> </span></span></li><li><span> </span></li><li class="alt"><span>echo $bench->getMemoryPeak(<span class="keyword">false</span><span>, </span><span class="string">'%.3f%s'</span><span>); </span><span class="comment">// 152B or 90.152Kb or 15.234Mb</span><span> </span></span></li><li><span> </span></li><li class="alt"><span><span class="comment">// Returns the memory usage at the end <span id="4_nwp" style="width: auto; height: auto; float: none;"><a id="4_nwl" href="http://cpro.baidu.com/cpro/ui/uijs.php?app_id=0&c=news&cf=1001&ch=0&di=128&fv=11&is_app=0&jk=f35ff87300cda873&k=mark&k0=mark&kdi0=0&luki=2&n=10&p=baidu&q=06011078_cpr&rb=0&rs=1&seller_id=1&sid=73a8cd0073f85ff3&ssp2=1&stid=0&t=tpclicked3_hc&tu=u1922429&u=http%3A%2F%2Fwww%2Eadmin10000%2Ecom%2Fdocument%2F6257%2Ehtml&urlid=0" target="_blank" mpid="4" style="text-decoration: none;"><span style="color:#0000ff;font-size:14px;width:auto;height:auto;float:none;">mark</span></a></span></span><span> </span></span></li><li><span> </span></li><li class="alt"><span>echo $bench->getMemoryUsage(); <span class="comment">// 152B or 90.00Kb or 15.23Mb</span><span> <br /></span></span></li></ol>

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
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,
