阵列字符串

Question

我有一个array(1) { [0]=> array(1) { ["id"]=> string(1) "2" } }

怎么能打破它为一个字符串，因为我只得到一个价值？

型号：

$table = $this->_table_products_manufacturers; 
     $query = $this->db->query("SELECT $table.id FROM $table WHERE $table.id = $manufacturer_id"); 

     return $query->result_array(); 

Answer 1

喜欢的东西：

$table = $this->_table_products_manufacturers; 
$query = $this->db->query("SELECT $table.id FROM $table WHERE $table.id = $manufacturer_id"); 
$result = $query->result_array(); 
return $result[0]['id']; 

是否有助于？
