PHP filesize() 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 filesize() Function.

The built-in PHP filesize() function returns the size of a specified file.


Following below is the syntax to use this function -

int filesize ( string $filename )

This function returns the file size in bytes or false (and can generate an error of the level E_WARNING) in case of an error.

Return Value

This built-in function returns the file size in bytes on success or false on failure.


Try out the below example -

   $filename = "/PhpProject/sample.txt";
   echo $filename . ': ' . filesize($filename) . ' bytes';


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

/PhpProject/sample.txt: 40 bytes
