如何搜索数组，找到正确的值，并仅更改这些行中的另一个“值”

如何搜索数组，定位值是否等于字符串，然后获取该行，找到另一个值，并替换它。 $value['ID'] == 2;我觉得这是一条错误的道路。

while($row = $result1 -> fetch_array())
{
    $columbs[] = $row;
}
$sort = array();
foreach($columbs as $key => $value) 
{
    $sort['schooltype'][$key] = $value['schooltype'];
    $sort['ID'][$key] = $value['ID'];
    foreach($columbs as $key=>$value)
    {
        if ($value['schooltype'] == "High School") 
        {
            $value['ID'] == 2;
            $sortbyschooltype = array("array" => $value['ID'], "SORT" => SORT_ASC);
        }
    }
}
