PHP | rewind() Function

PHP rewind() 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 rewind() Function.

The rewind() function rewinds the position of a file pointer to the beginning of the file.


Following below is the syntax to use this function -

bool rewind ( resource $handle )

It sets the file position indicator for stream to the beginning of the file stream. If we have opened a file in append ("a" or "a+") mode, any data written to a file can always be appended, irrespective of the file pointer position.

Return Value

This PHP function returns true on success, or false on failure.


Try out the below example -

   $handle = fopen("/PhpProject/sample.txt", "r+");

   fwrite($handle, "Long sentence");
   fwrite($handle, "Hello PHP");
   echo fread($handle, filesize("/PhpProject/sample.txt"));


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

Hello PHPence


Try out the below example -

   $file = fopen("/PhpProject/sample.txt", "r");

   fseek($file, "15");  // Change the position of file pointer
   rewind($file);  // Set the file pointer to 0
