write_file()

write_file($path, $data[, $mode = 'wb'])

Writes data to the file specified in the path. If the file does not exist then the function will create it.

Example:

$data = 'Some file data';
if ( ! write_file('./path/to/file.php', $data))
{
        echo 'Unable to write the file';
}
else
{
        echo 'File written!';
}

You can optionally set the write mode via the third parameter:

write_file('./path/to/file.php', $data, 'r+');

The default mode is ‘wb’. Please see the PHP user guide for mode options.
