本文介绍下,php在查询字符串中传递值的方法,举了二个例子,分别用来传递字符串值、数字值。有需要的朋友,参考下吧。
例1,在查询字符串中传递字符串值 <html> <body> <div align="center"> <p>Click a link to move to a new page:</p> Content 1<br /> Content 2<br /> Content 3<br /> <?php $page = trim (urldecode (stripslashes ($_GET['page']))); if (isset ($page) && $page != ""){ if (is_file ($page)){ require_once ($page); } else { echo "<p>很抱歉,您请求的页面不存在。</p>"; } } ?> </div> </body> </html> 登录后复制 例2,在查询字符串中传递数值 <html> <head> <title>查询字符串传递数值-bbs.it-home.org</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> </head> <body> <div align="center"> <p>Click a link to change the text color of the verbiage below:</p> Green<br /> Red<br /> Blue<br /> 重置信息 <?php if (isset ($_GET['color'])){ $color = intval ($_GET['color']); } else { $color = ""; } if ($color == 1){ $fontcolor = "00FF00"; } elseif ($color == 2){ $fontcolor = "FF0000"; } elseif ($color == 3){ $fontcolor = "0000FF"; } else { $fontcolor = "000000"; } ?><p style="color: #<?php echo $fontcolor; ?>; font-weight: bold;">欢迎访问程序员之家网站!</p><?php ?> </div> </body> </html> 登录后复制 |
