PHP is_link() Function

Hello folks! welcome back to a new edition of our tutorial on PHP. In this tutorial guide, we are going to be studying about the PHP is_link() Function.

The built-in PHP is_link() function checks whether a specified file is a link. If the file is a link then it returns true.


Following below is the syntax to use this function -

bool is_link ( string $filename )

Return Value

This function returns TRUE if the filename exists and is a symbolic link, otherwise it returns FALSE.


Try out the below example -

   $link = "/PhpProject/images";
   if(is_link($link)) {
      echo ("$link is a link");
   } else {
      echo ("$link is not a link");


When the above code is executed, it will produce the following result -

/PhpProject/images is not a link
