Redirect to another page in PHP

In PHP, how does one redirect a page to another? Three methods are listed here for your reference.

1. Use HTTP header information
That is, use the php header function. The HEADER function in PHP is used to send control commands that should have been specified by the HTTP protocol to the browser through the WEB server, such as declaring the type of returned information ("Context-type: xxx/xxx "), page attributes (" No cache "," Expire "), and so on.

To redirect an HTTP header to another page, follow these steps:
<?
If (isset ($ url ))
{
Header ("HTTP/1.1 303 See Other"); [thank you, Mr. Li Ling]
Header ("Location: $ url ");
Exit;
}
?>
Note that "Localtion:" is followed by a space.

II. Mark with HTML

The HTML tag is the REFRESH tag of META, for example:
<? If (! Isset ($ url) exit;?>
<HTML>
<HEAD>
<META HTTP-EQUIV = "REFRESH" CONTENT = "5; URL = <? Echo $ url;?>
</HEAD>
<BODY>
</BODY>
</HTML>

III. Implement with scripts

Example:
<?
$ Url = "http ://";
Echo "<! -- <Script language = "JavaScript"> ";
Echo "location. href = '$ url '";
Echo "</SCRIPT> --> ";
?>
