PHP5.4新特性之Array dereferencing support
一个盼望已久的特性，终于有了，转之～
Array dereferencing是个好东西, 有了Array dereferencing, 以前的这种写法就再也不必要了:
list($name,) = explode(",", "Laruence, male");
?>
取而代之的是:
$name = explode(",", "b, x")[0];
另外, Array derefencing也可以出现再赋值语句的左值中, 也就是理论上你可以这么写:
explode(",", "test1, test2")[3] = "phper";

The best way is to check your motherboard manual. If you can't find the manual, you can use a multimeter to measure it. Find the ground first, then you can determine the order of the rest of the wiring. How to connect motherboard VDG wiring When connecting the VDG wiring of the motherboard, you need to plug one end of the VGA cable into the VGA interface of the monitor and the other end into the VGA interface of the computer's graphics card. Please be careful not to plug it into the motherboard's VGA port. Once connected, you can
