How to use PHP code to achieve page jump (three methods)

header("Location: https://www.baidu.com/");

2. Use meta tags to jump to pages

In HTML, you can use meta tags to achieve page redirection Automatically jump. When the browser reads the meta tag, it will automatically jump to the specified URL. The code is as follows:

<meta http-equiv="refresh" content="5;url=https://www.baidu.com/">

The content parameter is a string separated by semicolons, the first value 5 represents waiting for 5 seconds before jumping, and the second value url is the URL address to be jumped. .

In addition to using PHP or meta tags to jump to pages, you can also use JavaScript to achieve it. The code is as follows:

<script>
window.location.href = "https://www.baidu.com/";
</script>

<script>
window.open("https://www.baidu.com/");
