Cannot use string offset as an array

1.if($value['five_work_info']){
2.                $five_work_info = json_decode($value['five_work_info'],true);
3.                $_POST['CHIN']['work']['five_work_info'] = array();
4.                $_POST['CHIN']['work']['five_work_info']['0']['company_name'] = $five_work_info['0']['name'];
5.                $_POST['CHIN']['work']['five_work_info']['0']['company_address'] = $five_work_info['0']['address'];
6. }
tp報錯 Cannot use string offset as an array 在line 4 ; 之后加了第三行的定義數組 = array（）后解決

 $arr=array() 這樣寫的原因,告訴程序這是數組。

這個問題是因為PHP5.X對String和數組的規定嚴格了
$far='boo';
$far[1][]='boo';
運行這段腳本就會產生這樣的錯誤。改正也非常簡單，只要加一句：
$far='boo';
$far=array();
$far[1][]='boo';
