Access返回的数组在localhost上运行，但在服务器上运行

Question

This works on localhost but not on server:

$x = preg_split("/#/", $val)[0];

I have wasted like 4 hours to notice that this was the problem. On the server no errors were shown and the php file was interpreted in a very strange way, if I had a die('ok') before this line it won't show anything.

$x = preg_split("/#/", $val);
$x = $x[0];

Works on server too.

And it's not about preg_split, it is the same with every function that returns an array.

Answer 1

You are running php 5.4 on localhost but php 5.3 (or some other) on the server

Function array dereferencing was added on php 5.4 see this
