    File Helper¶

    The File Helper file contains functions that assist in working with files.

    Loading this Helper¶

    This helper is loaded using the following code:

    ->load->helper('file');

    Available Functions¶

    The following functions are available:

    ($file)¶
    Parameters:
    • $file (string) – File path
    Returns:

    File contents or FALSE on failure

    Return type:

    string

    Returns the data contained in the file specified in the path.

    Example:

    $string=read_file('./path/to/file.php');

    The path can be a relative or full server path.

    Returns FALSE (boolean) on failure.

    Note

    The path is relative to your main site index.php file, NOT your controller or view files. CodeIgniter uses a front controller so paths are always relative to the main site index.

    Note

    This function is DEPRECATED.

    Use the native instead.

    Important

    If your server is running an open_basedir restriction this function might not work if you are trying to access a file above the calling script.

    ($path, $data[, $mode = 'wb'])¶
    Parameters:
