PHP页面跳转的方式有哪些？
PHP 页面跳转的三种方式
第一种方式：header()
header()函数的主要功能是将HTTP协议标头(header)输出到浏览器。
语法：
void header ( string $string [, bool $replace = true [, int $http_response_code ]] )
可选参数replace指明是替换前一条类似标头还是添加一条相同类型的标头，默认为替换。
第二个可选参数http_response_code强制将HTTP相应代码设为指定值。 header函数中Location类型的标头是一种特殊的header调用，常用来实现页面跳转。注意：1.location和“:”号间不能有空格，否则不会跳转。
举例：
<html> <?php /* This will give an error. Note the output * above, which is before the header() call */ header('Location: http://www.example.com/'); exit; ?>
注意：
header执行前不能有任何输出
location和:之间不能有空格
header后的php代码还会执行，所以需要注意使用exit;
第二种方式：meta标签
Meta标签是HTML中负责提供文档元信息的标签，在PHP程序中使用该标签，也可以实现页面跳转。 若定义http-equiv为refresh,则打开该页面时将根据content规定的值在一定时间内跳转到相应页面。
< meta http-equiv="refresh" content="1;url=http:// www.baidu.com">
第三种方式：javascript
通过使用windows.location.href=‘url’; 是页面自动跳转到新的地址
< ?php $url = "http://www.baidu.com"; echo "< script language='javascript' type='text/javascript'>"; echo "window.location.href='$url'"; echo "< /script>"; ?>
