PHP提交表单
二种提交方式，提交到其它页面和提交到本身见代码：<!DOCTYPE html>
<html>
<title>表单提交开始</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<body>
<a href="../index.php">返回首页</a>
<hr></hr>
<b>一、表单提交到另一个php上</b><br />
<form action="formTo.php" method="POST">
Name:<input type="text" name="username"><br />
Email: <input type="text" name="email"><br />
<input type="submit" name="submit" value="提交" />
</form>
<hr/>
<b>二、将一个表单 POST 给自己并在提交时显示数据：</b><br />
<br/>
<?php
if (isset($_POST['action']) && $_POST['action'] == 'submitted') {
echo '<pre>';
print_r($_POST);
echo '<a href="'. $_SERVER['PHP_SELF'] .'">返回重填</a>';
echo '</pre>';
} else {
?>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
Name:<input type="text" name="personal"><br />
Email: <input type="text" name="personal"><br />
Beer: <br>
<select multiple name="beer[]">
<option value="warthog">Warthog</option>
<option value="guinness">Guinness</option>
<option value="stuttgarter">Stuttgarter Schwabenbr</option>
</select><br />
<input type="hidden" name="action" value="submitted" />
<input type="submit" name="submit" value="submit me!" />
</form>
<?php
}
?>
</body>
</html>
formTo.php
<!DOCTYPE html>
<html>

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<a href="../index.php">返回首页</a>
<hr></hr>
<?php
// 自 PHP 4.1.0 起可用
echo "<br/>_POST"; echo $_POST['username'];
echo "<br/>_REQUEST";echo $_REQUEST['email'];
import_request_variables('p', 'p_');
echo "<br/>p_username";echo $p_username;
// PHP 6以后将无效。自 PHP 5.0.0 起，这些较长的预定义变量
// 可用 register_long_arrays 指令关闭。
echo "<br/>HTTP_POST_VARS"; echo $HTTP_POST_VARS['username'];
?>
