PHP jump, which redirects the browser to a specified URL, is a very common function. This function also has some detailed requirements, such as how many seconds to wait before jumping, whether to use JavaScript to implement the jump, etc. The following jump method takes a lot into consideration and is parameterized so that it can be used in specific projects.
<?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) { $out .= ' // --></mce:script>'; } if ($return) { return $out; } echo $out; exit; } ?>
