PHP $_GET

PHP $_GET can also be used to collect form data after submitting an HTML form (method="get").

$_GET can also collect data sent in the URL.

Suppose we have a page containing hyperlinks with parameters:

<html>
<body>
<a href="test_get.php?subject=PHP&web=W3school.com.cn">测试 $GET</a>
</body>
</html>
当用户点击链接 "Test $GET"，参数 "subject" 和 "web" 被发送到 "test_get.php"，然后您就能够通过 $_GET 在 "test_get.php" 中访问这些值了。
下面的例子是 "test_get.php" 中的代码：
实例
<html>
<body>
<?php 
echo "Study " . $_GET[&#39;subject&#39;] . " at " . $_GET[&#39;web&#39;];
?>
</body>
</html>
