PHP fwrite() 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 fwrite() Function.

The built-in PHP fwrite() function writes to an open file. This PHP function stops at the end of a file or when it gets to the specified length, whichever comes first.


Following below is the syntax to use this function -

int fwrite ( resource $handle , string $string [, int $length ] )

This PHP function can write the content of a string to file stream pointed to by handle.

Return Value

This function returns the number of bytes written on success, and false on failure.


Try out the below example -

   $file = fopen("/PhpProject/sample.txt", "w");
   echo fwrite($file, "Hello Webdesigntutorialz!!!!");


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



Try out the below example -

   $filename = "/PhpProject/sample.txt";
   $somecontent = "Add this to the file\n";

   if(is_writable($filename)) {
      if(!$handle = fopen($filename, 'a')) {
         echo "Cannot open file ($filename)";
   if(fwrite($handle, $somecontent) === FALSE) {
      echo "Cannot write to file ($filename)";
   echo "Success, wrote ($somecontent) to file ($filename)";
   } else {
      echo "The file $filename is not writable";


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

Success, wrote (Add this to the file) to file (/PhpProject/sample.txt)
