PHP跳转函数跟一个通用的操作提示类的编写
PHP跳转函数和一个通用的操作提示类的编写
PHP 跳转，即重定向浏览器到指定的 URL，是一个很常见的功能。这种功能也有一些细节性的要求，比如等待多少秒以后跳转，用不用JavaScript实现跳转，等等。下面的跳转方法考虑到很多，并参数化，可以用到具体的项目当中。
<?php /** * 重定向浏览器到指定的 URL * * @param string $url 要重定向的 url * @param int $delay 等待多少秒以后跳转 * @param bool $js 指示是否返回用于跳转的 JavaScript 代码 * @param bool $jsWrapped 指示返回 JavaScript 代码时是否使用 <mce:script type="text/javascript"><!-- 标签进行包装 * @param bool $return 指示是否返回生成的 JavaScript 代码 */ function redirect($url, $delay = 0, $js = false, $jsWrapped = true, $return = false) { $delay = (int)$delay; if (!$js) { if (headers_sent() || $delay > 0) { echo <<<EOT <html> <head> <meta http-equiv="refresh" content="{$delay};URL={$url}" /> </head> </html> EOT; exit; } else { header("Location: {$url}"); exit; } } $out = ''; if ($jsWrapped) { $out .= '<script language="JavaScript" type="text/javascript">'; } $url = rawurlencode($url); if ($delay > 0) { $out .= "window.setTimeOut(function () { document.location='{$url}'; }, {$delay});"; } else { $out .= "document.location='{$url}';"; } if ($jsWrapped) { $out .= ' // -->'; } if ($return) { return $out; } echo $out; exit; } ?>
一个通用的操作提示类的编写
在设计一些系统的时候，经常需要给用户进行操作提示。这种提示很重要，友好的提示能够提升用户对系统的好感度。操作提示有很多设计，下面是我的一个简陋的方案，仅抛砖引玉。
<?phpclass Tips{ private $tips; static private $_instance; private function __construct($string, $url) { $this->tips = "<meta http-equiv="refresh" content="4;url=$url"><div style="border:1px solid #B4D8F4; width:320px; height:120px; margin:0 auto; font-size:12px;"> <div style="background-color:#CDE6F9; height:20px;"></div> <div align="center" style="font-size:14px; font-weight:bold; margin:20px 0 20px 0;">$string</div> <div align="center">
<a href="%24url">返回</a> （4秒后自动返回）</div>
</div> "; return $this->tips; } public function __toString(){ return $this->tips; } private function __clone(){} public static function get_tips($string, $url) { if( FALSE == (self::$_instance instanceof self) ) { self::$_instance = new self($string, $url); } return self::$_instance; }}?>这个类功能很简单，就是实现了4秒后跳转到某个链接，或者点击跳到那个链接。
__toString()这个函数很重要，它可以实现类对象的字符串输出。
如何使用这个类呢？
include_once("./tips_class.php");$hit = "错误：两次输入的密码不一致";$jump = "../login.php";echo $tips = Tips::get_tips($hit, $jump);
