PHP prompts and redirects to the new page to redirect to the new page.

This article describes how to use PHP to pop up a prompt box and jump to a new page, that is, what you think is redirection. for the following example, you can refer to the next two days to write a demo, you need to use prompts and jump, the main page is not high requirements, feel that there is no need to use AJAX, JS, etc., so I studied how to prompt and jump in PHP.

At first, we used the following:
The code is as follows:
Echo "script" alert ('sucess '); parent. location. href ='/user/index'; script ";

Alert contains the prompt message and href is the page to jump to after the prompt.

Later I remembered that there was a redirect () redirection method in the TP framework, so I went and looked at it.

However, TP does not bring a pop-up window, so I changed it myself:
The code is as follows:
Echo "script" alert ('No loginid'); script ";
Echo" ";

$ Url is the page to jump to. at the same time, this can also control the jump time. The value 0 after content indicates that the page will jump after 0 seconds.

Here, Mo Li provides two direct jump methods:
The code is as follows:
Header ("Location:". PSYS_BASE_URL. "user/index ");

And
The code is as follows:
Header ("refresh: {$ time}; url = {$ url }");

There are no prompts for these two methods, so you can jump directly. The following is recommended.

Finally, there is another problem. after the jump code is followed by a return, because the following statement will be executed.
