使用2个参数在多维数组中搜索键

Question

I have a multidimensional array and I would like to search with 2 parameters : city and zip.

My array :

$result=array(2) { 
          [0]=> array(2) 
              { 
                  ["city"]=> string(9) "Paris" 
                  ["zip"]=> string(5) "75000" 
              } 
          [1]=> array(2) 
              {
                  ["city"]=> string(9) "Paris"
                  ["zip"]=> string(5) "75100" 
              }
          }

Ex : search the key value for city=paris and zip=75100

Key=1

An idea ?

Answer 1

Use this function..

function find_key($city, $zip) {

    foreach($result as $key => $value) {
        if($value['city'] == $city && $value['zip'] == $zip) {
             return $key;
        }
    }

    return FALSE;
}

$key = find_key('paris','75100');
if($key) {
    echo 'Found at key:'.$key;
} else {
    echo 'Not Found';
}
