The example analyzes the principles and implementation methods of HTTP authentication, which has some reference value, for more information about HTTP authentication in PHP, see the following example. Share it with you for your reference. The specific analysis is as follows:

The combination of the. htaccess file and. htpasswd file is used to prevent users from accessing directories on some servers. These files contain information about a directory and password that the user is allowed to access. HTTP authentication can be performed by sending special HTTP header information instead of using the. htaccess file.

The code is as follows:

<? Php
If (! Isset ($ _ SERVER ['php _ AUTH_USER ']) {
Header ("WWW-Authenticate: Basic realm = \" My Private Area \"");
Header ("HTTP/1.0 401 Unauthorized ");
Print "You need valid credentials to get access! \ N ";
Exit;
} Else {
If ($ _ SERVER ['php _ AUTH_USER '] = 'Mani ') & ($ _ SERVER ['php _ AUTH_PW '] = 'W # m3nt0r ')){
Print "Welcome to the private area! ";
} Else {
Header ("WWW-Authenticate: Basic realm = \" My Private Area \"");
Header ("HTTP/1.0 401 Unauthorized ");
Print "You need valid credentials to get access! \ N ";
Exit;
}
}
?>
