syntax question

[sinista]

just been looking at some code

 

<?php
function updateStuff() {
    DB::query('LOCK TABLES `a`, `b`, `c` WRITE');
    /* some SQL Operations */
    someFunction();
    /* more SQL Operations */
    DB::query('UNLOCK TABLES');
} ?>

 

my question is what does DB::query do?

[RussellReal]

DB::Query is essentially a static method call of the DB Class..

[Alex]

:: is the scope operator. As RussellReal said, it's used for calling static methods. Which basically means the method belongs to the class itself, rather than an instance of it. Depending on how high your error reporting is set you may not get an error when trying to access a non-static method using the scope operator, so be careful.

[sinista]

ideal, so using :: I can use class methods without creating an object,

 

cheers

[RussellReal]

if those methods are static..
