How to automatically jump to the specified page in php

In PHP, you can use the header() function to automatically jump to the specified page; you only need to add "header("location: the address of the specified page")" or "header() at the beginning of the PHP document 'Refresh: time value, Url = address of the specified page')" code is enough.

php automatically jumps to the specified page

This can be achieved using the header() function. Enter the following code at the beginning of the php page:

<?php
header("location:http://www.php.cn");
?>

Then, we name it 1.php. When accessing 1.php , it will automatically jump to the www.php.cn page. What needs to be emphasized here is that when using this method, this line of code must be written at the front.

If you want to achieve scheduled automatic jump, you need to enter the following code at the beginning of the php page:

header('Refresh:time,Url=url页面地址');

Example:

header('Refresh:3,Url=http://www.php.cn/');   //3s后跳转
echo '3s 后跳转';
//由于只是普通页面展示，提示的样式容易定制
die;

Note :

1. There cannot be a space between location and ":", otherwise an error will occur.

2. There cannot be any output before using the header.

3. The PHP code after the header will also be executed.

Supplement: Use meta to achieve jump

Enter the following code at the head of the html page:

<meta http-equiv="refresh" content="5;url=http://www.php.cn">;

Then, we name the page 2.php or 3.htm, when accessing 2.php or 3.htm, it will automatically jump to the page www.php.cn
. Note that the number 5 in the content means how long it took to start. Jump, the setting here is 5, which means that it will take 5 seconds for the page to jump to the target page. It is recommended that you set the jump time not to exceed 10 seconds.
