PHP need to count how many instaneces of specific value in array - php

Question

I have a JSON file which structure looks like this (very simplified):
[
{
"customerId": "M12345",
"houses": [
{
"id": "OBJ12345_1731321200",
"status": {
"id": "4",
"name": "Sold"
}
],
"plots": [
{
"id": "OBJ12345_1771637082",
"status": {
"id": "4",
"name": "Sold"
}
],
"projects": [],
"farms": [],
"commercialPropertys": [],
"condominiums": [],
"foreignProperties": [],
"premises": []
}
]
I have figured out how to count how many "houses" or "plots" there is:
$content = file_get_contents('estateList/estateList.json');
$GetEstateList = json_decode($content);
count($GetEstateList[0]["houses"]);
count($GetEstateList[0]["plots"]);
BUT Trying to figure out using php how to count how many objects which have a condition status(id:4)

Answer 1

I think you will need to use a loop in order to count the objects, i would use a foreach loop, bellow is an example :
$count = 0;
foreach ( $GetEstateList[0] as $key => $value){
if (isset($value['status']) && $value['status']['id'] === "4") {
$count++;
}
}

First, you need to enter the GetEstateList array, then you need to do a cycle for each type (for now types showed are plots and houses), then you need another cycle, because each type is an array of elements and can have more than one estate.
So, try this code:
// Counter variable for condition expressed after (status == 4)
$counter = 0;
// Enter the array and get `customerId`, `houses` and `plots`,
// but we only need the types of estate, so only `houses` and `plots`, in this case
foreach ( $GetEstateList as $estate_array => $array_attr ) {
// We only need `houses` and `plots` (increasing algorithm performance)
if ( $array_attr == "houses" || $array_attr == "plots" ) {
// We're checking all types of estates (all `houses` and all `plots`)
foreach ( $array_attr as $type => $parameter ) {
// So, we can get `status` of every estate
if ( $parameter == "status") {
// And finally we can get `id` for each estate `status`
if ( $parameter["id"] == "4" ) {
$counter++;
}
}
}
}
}
Notice: the code above cannot work if the written JSON structure is too different from the original.

I figured it out myself...
Maybe not the "correct" way but it works! :)
Feel free to comment on any improvement or modifications...
$StatusCount = 0;
foreach ($GetEstateList[0] as $GetEstateType) {
foreach ($GetEstateType as $GetEstate) {
if ($GetEstate["status"]["id"] == "4") {
$StatusCount++;
}
}
}
