public SplFileInfo::openFile ( string $open_mode = "r" , bool $use_include_path = false , resource $context = null ) : SplFileObject

When set to true, the filename is also searched for within the include_path


Refer to the context section of the manual for a description of contexts.

Return Values

The opened file as an SplFileObject object.


A RuntimeException if the file cannot be opened (e.g. insufficient access rights).

= new SplFileInfo('/tmp/foo.txt');

if (
$fileinfo->isWritable()) {
