[date_created] => 2012-03-15 16:11:54

[body] => dhfdhdf
[contact_author] => mirko
[date_created] => 2012-03-15 16:11:56

[category_id] => 26
[tag] => fhdhfdhfd
[info_type_id] => 4
[user_id] => 3
)

How can I search a multidimensional array and count number of results (for example I want to search for info_type_id with value of 4)?
如何搜索多维数组并计算结果数量（例如，我想搜索值为 4 的 info_type_id）？

Use array_filterto filter the array:
使用array_filter该滤镜阵列：
function test($arr) {
return $arr["info_type_id"] == 4;
}
echo count(array_filter($yourArray, "test"));

with foreach?
与foreach？
function searchMyCoolArray($arrays, $key, $search) {
$count = 0;
foreach($arrays as $object) {
if(is_object($object)) {
$object = get_object_vars($object);
}
if(array_key_exists($key, $object) && $object[$key] == $search) $count++;
}
return $count;
}
echo searchMyCoolArray($input, 'info_type_id', 4);

You should try this :
你应该试试这个：
$counter = 0;
$yourArray; // this var is your current array
foreach($yourArray as $object){
if($object->info_type_id == 4){
$counter++;
}
}
