Getting The Current URI In PHP

The $_SERVER superglobal array contains lots of information about the current page location. You can print this off in full using the following line of code.

echo ''.print_r($_SERVER, true).'';

Although this array doesn't have the full URI we can piece together the current URI using bits of the $_SERVER array. The following function does this and returns a full URI.

function currentUri(){


 $uri = 'http';


 if(isset($_SERVER['HTTPS'])){


  if($_SERVER['HTTPS'] == 'on'){


   $uri .= 's';


  };


 };


 $uri .= '://';


 if($_SERVER['SERVER_PORT'] != '80'){


  $uri .= $_SERVER['SERVER_NAME'].':'.$_SERVER['SERVER_PORT'].$_SERVER['REQUEST_URI'];


 }else{


  $uri .= $_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'];


 };


 return $uri;


}

You can use this function like this:

echo currentUri();
