For example, you can use the static keyword with the getName() method of the OpenedFile class as follows:15class OpenedFile {16    public static function getName() {17        return 'opened_file.txt';18    }19}20You can also use the static keyword with class properties, class constants, and class methods at the same time. For example, you can use the static keyword with the $name property, the OPENED_FILE constant, and the getName() method of the OpenedFile class as follows:21class OpenedFile {22    public static $name = 'opened_file.txt';23    const OPENED_FILE = 'opened_file.txt';24    public static function getName() {25        return 'opened_file.txt';26    }27}

1$of = new OpenedFile('test.txt');2$of->lock();3$of->write('This is a test.');4$of->unlock();5$of->close();6The code above is the same as the previous one. The only difference is that the lock() and unlock() methods are used. When you call the lock() method, the file is locked for writing. When you call the unlock() method, the file is unlocked. The lock() method takes one optional parameter, which is the mode in which the file is to be locked. The mode can be one of the following:7The following example shows how to use the lock() and unlock() methods:8$of = new OpenedFile('test.txt');9$of->lock();10$of->write('This is a test.');11$of->unlock();12$of->close();13The lock() method takes one optional parameter, which is the mode in which the file is to be locked. The mode can be one of the following:14The lock() method returns TRUE if the file is locked successfully, and FALSE otherwise. The unlock() method returns TRUE if the file is unlocked successfully, and
