Definition and Usage

The fpassthru() function reads from the current position in a file - until EOF, and then writes the result to the output buffer.

Note: When using fpassthru() on a binary file on Windows, remember to open the file in binary mode.

Tip: Call rewind() to set the file pointer to the beginning of the file if you have already written to the file.

Tip: To just dump the contents of a file to the output buffer, use the readfile() function instead.
