PHP is_uploaded_file() Function


Hello dear readers! welcome back to another edition of our tutorial on PHP. In this tutorial guide, we are going to be discussing about the PHP is_uploaded_file() Function.

The built-in PHP is_uploaded_file() function checks whether or not the specified file is uploaded via HTTP POST.

Syntax

Following below is the syntax to use this function -

bool is_uploaded_file ( string $filename )


This function returns true if the file named by filename is uploaded via HTTP POST. This is mostly useful if there is any chance that anything done with the uploaded files can reveal their contents to the user or even other users in same system.

Return Value

This built-in function returns true if the file is uploaded via the HTTP POST, otherwise false.

Example

Try out the below example -

<?php
   $file = "/PhpProject/simple.txt";
   if(is_uploaded_file($file)) {
      echo ("$file is uploaded via HTTP POST");
   } else {
       echo ("$file is not uploaded via HTTP POST");
   }
?>

Output

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

/PhpProject/simple.txt is not uploaded via HTTP POST
