我有这个数组（为了便于阅读而缩短）
array(10) {
[0] => array(23) {

我想要实现的是为具有特定account_id的阵列接地，以获得该玩家的杀戮，死亡和助攻的值。这就是我试过的：
function searchForPlayer($id, $array) {
foreach ($array as $key => $val) {
if ($val['account_id'] === $id) {
return $key;
}
}
return null;
}
$player = searchForPlayer($accountid, $players);
但是每次都返回null。我是php的新手，所以如果我做错了什么就不会感到惊讶。谢谢！
答案 0 :(得分：1)
function searchForPlayer($id, $array) {
foreach ($array as $key => $val) {
if ($val['account_id'] == $id) {
return $key;
}
}
return null;
}
编辑：基于编辑数组结构，可以为主数组中的每个元素调用方法。
function mainSearchForPlayer($id, $mainArray) {
foreach($array as $k => $val) {
$result = searchForPlayer($id, $val);
if($result) break;
}
return $result;
}
然后致电：
$player = mainSearchForPlayer($accountid, $array);
===在php中按类型比较，这意味着如果你通过＆＃39; 1＆＃39;你的数组中的id是1，永远不等于
否则你可以通过这种方式检查类型：
var_dump($accountid);
如果这是一个字符串值，则可以解析为int：
$accountid = intval($accountid)

试试这个递归函数：
function array_searchRecursive($needle, $haystack, $path=array()) {
foreach( $haystack as $key => $val ) {
if( is_array($val) && $sub = array_searchRecursive($needle, $val, $path)) {
$path = array_merge($path, array($key), $sub);
return $path;
} elseif($val == $needle) {
$path[] = $key;
return $path;
}
}
return false;
}
