How to Implement Page Redirection after a Defined Time in PHP?

In PHP, there's an efficient mechanism to redirect a user to another page after a predetermined amount of time has elapsed. This feature mimics the automatic redirection seen on Gmail after logging in.

Solution:

Utilizing the header() function, you can swiftly establish a header that will seamlessly redirect the user to a designated URL after a specified time interval. The following code exemplifies this technique:

<code class="php">header("refresh:5;url=wherever.php");</code>

In this instance, the header is configured to redirect the user to "wherever.php" after a delay of 5 seconds.

Important Note:

It's crucial to bear in mind that header() must be called before any meaningful output is transmitted. This includes HTML,空白行或PHP生成的输出。所以，务必谨慎地调用 header() 以免引发潜在问题。
