Usage and Examples of PHP fopen() Function

PHP Filesystem Reference Manual

The fopen() function can open a file or URL. If fopen() fails, it can return false and an error message. We can hide the error output by adding " @" before the function name.

Syntax

resource fopen ( string $filename , string $mode [, bool $use_include_path = FALSE [, resource $context ] ] )

The fopen() function binds a named resource to a stream specified by the file name.
