如何使用stdClass在数组中搜索？

Question

I have array with stdClasses:

$a = new \stdClass();
$a->name = "aaa";
$a->type = "1";

$b = new \stdClass();
$b->name = "bbb";
$b->type = "2";

$c = new \stdClass();
$c->name = "ccc";
$c->type = "1";

$array = array($a, $b, $c);

$count = 0;

foreach ($array as $arr) {
    if ($arr->type == 1) {
        $count++;
    }
}

Is better way to count types with value 1 than foreach? I would like counting many values so foreach is uncomfortable.

Maybe array_search or array_map?

You can use array_filter:

http://php.net/manual/tr/function.array-filter.php

example:

$a = new \stdClass();
$a->name = "aaa";
$a->type = "1";

$b = new \stdClass();
$b->name = "bbb";
$b->type = "2";

$c = new \stdClass();
$c->name = "ccc";
$c->type = "1";

$array = array($a, $b, $c);

$count = count(array_filter($array, function($d){
     return $d->type === "1";
}));
