getRequestInfo.php

<html><body><form action="scripts/showRequestInfo.php" method="post"><fieldset>    <label for="first_name">First Name:</label>    <input type="text" name="first_name" size="20" /><br />    <label for="last_name">Last Name:</label>    <input type="text" name="last_name" size="20" /><br />    <label for="email">E_Mail Address:</label>    <input type="text" name="email" size="20" /><br />    <label for="facebook_url">Facebook URL:</label>    <input type="text" name="facebook_url" size="20" /><br />    <label for="twitter_handle">Twitter Handle:</label>    <input type="text" name="twitter_handle" size="20" /><br /></fieldset><br /><fieldset class="center">    <input type="submit" value="Join the Club" />    <input type="reset" value="Clear and Restart" /></fieldset></form></body></html>

在scripts目录下的showRequestInfo.php

<HTML><BODY><div id="content"><?phpforeach($_REQUEST as $value){echo "<p>". $value ."</p>";}?></div></BODY></HTML>

也可以用这种形式：

<?phpforeach($_REQUEST as $key => $value){echo "<p>For" . $key . ", the value is " . $value ."</p>";}?>
