Parse error: syntax error, unexpected '[' in C:AppServwwwgenerate_order.ph,该怎么处理

Parse error: syntax error, unexpected '[' in C:\AppServ\www\generate_order.ph
这个问题出在哪里？？

if (! $dsql->ExecuteNoneQuery ( $inQuery )) {<br />	ShowMsg ( 'Database error！', '-1' );<br />	exit ();<br />}<br /><br />$mid = $dsql->GetOne ( "SELECT * FROM `#@__im_order` WHERE email = '$email' ORDER BY order_id desc" )["order_id"];<br />$OrdId = $mid;

------解决思路----------------------
你的 php 版本低于 5.4

改为
$mid = $dsql->GetOne ( "SELECT * FROM `#@__im_order` WHERE email = '$email' ORDER BY order_id desc" );
$OrdId = $mid["order_id"];
