我有一个foreach循环，用于数组$students，我试图将从表单中获得的paramater$find与$students数组的$key值进行比较-

我把这个从芬兰语翻译过来，所以可能会有错别字，但问题在于语法...

      //values come from a file
      $students[$key] = array('key' => $key, 'name' => $name, 'occ' => $occ);

        foreach ($students as $value) {

            //This doesn't work - $find comes from a form
                        if ($value["key"] != $find) {
                        $phase= "Not found";
                        $enroll= "";
                       //echo "$phase $enroll";
                       continue;
                        }

            //This works
            elseif ($value["key"] == $find) {

                $phase= $value["name"] . "(" . $value["key"] . "):";

                    if ($value["occ"] == "1") { 
                    $enroll= " yes";
                    continue;
                    } 

                    elseif ($value["occ"] == "0") {
                    $enroll=  "no";
                    continue;
                    } 
            } 

            //It prints out for example "John(1234): yes"
            //But nothing if the studentnumber = key doesn't match.. 
            echo "$phase $enroll";


        }
