我想使用此代码的array_diff我也得到输出但同时发生错误
“数组到字符串转换”
我正在使用codeigniter,我在第二个数组(listingdata)中使用方法$ this-> input-> post(); ,但是我的第一个数组获得了一些动态键和值,然后这两个数组diff给了我输出但是有时候会出错。
请帮帮我
任何解决方案总是受欢迎。
if(isset($_POST)){
foreach($_POST as $key => $value) {
$arr[$key] = $value; // making array
}
}
$result = array_diff($arr,$listingdata);
print_r($result);
print_r($arr);
print_r($listingdata);
我的$ arr数组

答案 0 :(得分:0)
这是因为array_diff比较了两个比较值与字符串后的值(参见documentation notes)。
您的两个数组都包含另一个数组(ebay_user
和第二个pictureUrl
)。
请参阅this answer了解递归数组_diff,它适用于您的情况。
