In PHP, the use of the header function is very large, the header can not only send the original HTTP header information to the client, but also can directly implement the file download operation

The header function is most commonly used not for downloading but for sending HTTP classes.

Jump

It will execute the last one, but conditionally, for example:

Header ('location:http://www.111cn.net '); header (' location:http://header(' Location : Http://www.baidu.com '); // this will jump to Baidu

Send status

Output status value to browser, primarily for access control

<?  Header(' http/1.1 401 Unauthorized 'header(' status:401 unauthorized '?) >

For example, to restrict a user from accessing the page, you can set the status to 404, as shown below, so that the browser is displayed as if the page does not exist

<?  Header(' http/1.1 404 Not Found 'header("status:404 not Found"?>

Download
<?  $filename = ' path + actual filename '//header(' content-type:application/ PDF '//header(' content-disposition:attachment; filename= ' file name when saving. pdf "'   ReadFile("$filename"exit?>

The header function is transformed accordingly
Header (' Content-type:application/octet-stream '); // type of output, depending on the MIME table provided below, select the appropriate type Header (' content-disposition:attachment; filename= "Download display name. rar"); // Download the displayed name ReadFile (' File name on the server. rar '); //Output file contents
