$_SERVER[‘PHP_SELF’], $_SERVER[‘SCRIPT_NAME’] & $_SERVER[‘REQUEST_URI’] – All this super global variable will return the same output i.e., /page/2.php

$_SERVER[‘REQUEST_URI’] is unique from all this, because this will get query string from the webpage but other two wont give query string.

Example: URL:

Select Code
</p> <p><?php</p> <p>echo "PHP_SELF - ".$_SERVER['PHP_SELF'];</p> <p>echo "SCRIPT_NAME - ".$_SERVER['SCRIPT_NAME'];</p> <p>echo "REQUEST_URI - ".$_SERVER['REQUEST_URI'];</p> <p>?></p> <p>


PHP_SELF – /page/2.php

SCRIPT_NAME – /page/2.php

REQUEST_URI – /page/2.php?name=tobby


Here is the various methods of php code to get website name and currently using webpage.

Select Code
</p> <p><?php<br /> $domain=$_SERVER['SERVER_NAME']; // Returns<br /> $domain1=$_SERVER['HTTP_HOST']; // Returns<br /> $url=$SERVER['PHP_SELF']; // Returns /page/2.php<br /> $url1=$SERVER['SCRIPT_NAME']; //Returns /page/2.php<br /> $url2=$SERVER['REQUEST_URI']; //Returns /page/2.php<br /> echo $domain.$url1;<br /> ?></p> <p>



Use of Getting Current Webpage URL
