php - 如何将mysql数组转换成php数组

Question

我有一个如下所示的数组:

Array ( [0] => stdClass Object ( [city_name] => Hyderabad ) 
        [1] => stdClass Object ( [city_name] => Visakhapatnam )
        [and so on..] => and so on...
      )

此数组由此代码块返回:::

 $query = "select city_name from city";
 $result = $CI->Dbmodel->customQueryResult($query);
 print_r(array_values($result));

我想将上面的数组转换为:

array('Hyderabad','Visakhapatnam','and so on..')

php 是否提供任何内置函数？

我该怎么做？..任何帮助或建议都会很有帮助..提前致谢

Answer 1

这应该有效:

$query = "select city_name from city";
$result = $CI->Dbmodel->customQueryResult($query)->result_array();
print_r($result);
