thinkphp hint Syntax Error unexpected how to solve

Very strange, the program in the local same server software under the normal operation, after the error:

Syntax error, unexpected ' [' 47th line,

Check the corresponding row, write a value of a query array

{$user =cookie (' user ') [' ID ']}

Carefully checked, the local running is PHP 5.6N, the server is running php5.3n, may be related to the PHP version, after the replacement version is indeed normal.

I later learned that PHP5.4 the following does not support this type of writing, instead:

$user =cookie (' user ');
$user [' id '];

Re-test found that everything is normal, it is likely that PHP 5.4 below does not support $STR [0][0] This writing, have encountered the same problem friends may wish to try.
