php ：数组到字符串的转换。如何解决这个问题？

Question

我打算用 , 分隔数组的元素，但出现错误

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。

Answer 1

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);

Answer 2

您的示例中似乎有各种不必要的代码，而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

Answer 3

$data = ['first'=>'One','sec'=>'Two','third'=>Three];
echo implode(' ',$data);

输出为

One Two Three
