I was searching the php online docs and google but I guess because of the characters I cannot find the reference. What does this mean: "
->" ?
eg:
Thanks!

It's accessing the property "dir" in "$language".
Read up on classes and object oriented PHP

You'd use it in these situations:
Code: Select all
<?PHP
class Lang
{
public $dir = 'ltr';
public function setDir($dir)
{
$this->dir = $dir;
}
public function getDir()
{
return $this->dir;
}
}
$language = new Lang();
$language->dir = 'rtl'; //The "language" object now has "rtl" as the value of it's property "dir"
echo $language->dir; //Echoes "rtl"
$language->setDir('ltr');
echo $language->getDir();//You can also use -> to access object methods
