PHP fpassthru() 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 fpassthru() Function.

The built-in PHP fpassthru() function reads all the data from the current position in an open file until EOF and writes the result to an output buffer.

Syntax

Following below is the syntax to use this function -

int fpassthru ( resource $handle )


Before we can make use of this function in a binary file on a Windows system, the file must first be opened in a binary mode.

Return Value

This built-in function returns the number of characters passed on success or FALSE on failure.

Example

Try out the below example -

<?php
   $file = fopen("/PhpProject/sample.txt", "r");
 
   // Read first line
   fgets($file);

   // Send rest of the file to the output buffer
   echo fpassthru($file);
   fclose($file);
?>

Output
