PHP是最常用的服务器端脚本语言之一,特别适合处理HTML表单数据。以下是基本处理流程:
<!-- HTML表单 -->
<form method="post" action="process.php">
用户名: <input type="text" name="username">
密码: <input type="password" name="password">
<input type="submit" value="提交">
</form>
<?php // process.php ?>
$username = $_POST['username'];
$password = $_POST['password'];
// 数据处理逻辑...
CGI(Common Gateway Interface)是Web服务器与外部程序交互的标准协议:
#!/usr/bin/perl
use CGI;
my $cgi = new CGI;
my $username = $cgi->param('username');
my $password = $cgi->param('password');
print "Content-type: text/html\n\n";
print "<html><body>";
print "用户名: $username<br>";
print "密码: $password";
print "</body></html>";
处理用户输入时必须考虑安全性:
