cannot use string offset as an array php,php代码修改,Cannot use string offset as an array

下面的这段代码报错,Uncaught PHP Exception SymfonyComponentDebugExceptionFatalThrowableError: “Cannot use string offset as an array” at /var/www/dot/src/AppBundle/BlogService/BlogMenu.php line 201

可以看出是Cannot use string offset as an array

中文意思大概不能使用字符串偏移作为数组

201行 $listData[$i][‘item’] = $item;

请问,这个该怎么改,能帮忙改下吗?

private function toList($lists)

{

if ($lists == null) {

return null;

}

$listData = ‘’;

$prevElement = ‘’;

$i = 0;

$item = ‘’;

$j = 0;

foreach ($lists as $list) {

switch ($list[‘type’]) {

case ‘post’:

$item = $this->getPost($list);

break;

case ‘link’:

$item = $this->getLink($list);

break;

case ‘header’:

$item = $this->getHeader($list);

break;

case ‘category’:

$item = $this->getCategory($list);

break;

}

if ($list[‘parent’] == 1 && $i > 0) {

if ($prevElement[‘parent’] == 0) {

$j = $i - 1;

}

$listData[$j][‘child’][] = $item;

} else {

$listData[$i][‘item’] = $item;

}

$prevElement = $list;

$i++;

}

return $listData;

}
