一、php和表单
1.POST方法手动发送数据:
二者部分区别:
GET:
1.将信息聚集起来作为URL一部分传送
2.传送数量有限
3.公开传送,诸如密码信息会暴露
4.创建的表单可以添加为书签。
POST:
1.传递的信息用户看不到
用法示例:
html文件:ws.html
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>test</title><base> <div id="awindow"> <form action="handle.php" method="post"> <p> Name:<select name="title"> <option value="Mr">Mr</option> </select> <input type="text" name="name" size="20"></p> <input type="submit" value="send"> </form> <br> php文件:handle.php <br> <p></p> <p></p> <pre name="code" class="sycode"> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>test</title><base> <div id="awindow"> <?phpini_set ('display_errors', 1);error_reporting(E_ALL|E_STRICT);<strong><span style="color:#ff0000;">$title=$_POST['title'];$name =$_POST['name'];</span>print "<p> hello <span style="color:#ff0000;">$title $name</span>";?> 输入:myname </p> <p></p> <p>结果:hello Mr myname</p> <p>2.GET传送数据<br> <br> </p> <p></p> <pre name="code" class="sycode"> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>test</title><base> <div id="awindow"> <ul> <li><a href="<strong"><span style="color:#ff0000;">"handle.php?name=Charles</span>">Charles</a></li> </ul> <br> php文件:handle.php <p></p> <p></p> <pre name="code" class="sycode"> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>test</title><base> <div id="awindow"> <?phpini_set ('display_errors', 1);error_reporting(E_ALL|E_STRICT);<strong><span style="color:#ff0000;">$name=$_GET['name'];print "<p> hello $name";</p></span>?> <br> <br> <p></p> </div>

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
