如何在Codeigniter中将SQL结果字符串转换为数组？

Question

I need transform the [pictures names] string to an array. How to do it?

Answer 1

To convert your $array 1 [picture_names] into an array itself, you can use the " explode() " function.

array explode ( string $delimiter , string $string [, int $limit = PHP_INT_MAX ] )

Ie in your specific example:

$results = $this->db->get()->result_array();
$exp_results = explode(',', $results);

Which should give an array as such:

$exp_results = Array (
    0 => 21
    1 => 22
    2 => 25
    3 => 27
    4 => .... etc
)

Answer 2

Add these lines after query

$result = $this->db->get()->result_array();
foreach($result as $key=>$row) {
    $result[$key]['picture_names'] = explode(',',$row['picture_names']);
}
