我要用,分隔数组的元素，但我有一个错误
Array to string conversion
我的 php 代码：
// get sliders from database
$all_slider = $this->db_submit_product->get_slider($shoe_ID);
$data['my_slider'] = array();
foreach ($all_slider as $row) {
array_push($data['my_slider'], $row->pic);
}
// Use $data['my_slider']
$filename_arr[] = $data['my_slider'];
$file_coma = implode(',', $filename_arr);
// line of error is about last line
怎么了？谢谢。
尝试从变量filename_arr中删除括号。
// Use $data['my_slider']
$filename_arr = $data['my_slider'];
$file_coma = implode(',', $filename_arr);
您的示例中似乎有各种不必要的代码，并且您似乎不太了解数组。
$all_slider = $this->db_submit_product->get_slider($shoe_ID);
$pic_list = array();
foreach ($all_slider as $row) {
$pic_list[] = $row->pic;
}
$file_coma = implode(',', $pic_list);
// put the pic_list array into $data for the View.
$data = array();
$data['slider'] = $pic_list;
变量$file_coma现在应该包含$row->pic中任何内容的逗号分隔列表。
$data = ['first'=>'One','sec'=>'Two','third'=>Three];
echo implode(' ',$data);
输出为
One Two Three
