Select the value from an associative massive array - php

Question

I am trying to get some value from the massive array, and there occured some problem.
I have such array:
array(2) {
[0]=>
array(23) {
["ITEM_ID"]=>
int(2331)
["ITEM_TYPE_ID"]=>
string(1) "1"
["CART_ITEM_ID"]=>
string(0) ""
["SAVED_TYPE_ID"]=>
string(0) ""
["ITEM_NAME"]=>
string(17) "TEST STOCK LEVELS"
["ERROR"]=>
string(0) ""
["PROPERTIES"]=>
array(1) {
[522]=>
array(1) {
[0]=>
string(4) "1122"
}
}
["PROPERTIES_INFO"]=>
array(1) {
[522]=>
array(12) {
["USAGE_TYPE"]=>
string(1) "1"
["CONTROL"]=>
string(7) "LISTBOX"
["TYPE"]=>
string(1) "1"
["NAME"]=>
string(11) "TEST OPTION"
["VALUES"]=>
array(1) {
[0]=>
string(4) "1122"
}
["REQUIRED"]=>
string(1) "1"
["PARENT_PROPERTY_ID"]=>
string(0) ""
["PARENT_VALUE_ID"]=>
string(0) ""
["TEXT"]=>
array(0) {
}
["CONTROL_PRICE"]=>
int(0)
["ORDER"]=>
string(1) "1"
["QUANTITY_ACTION"]=>
string(1) "1"
}
}
["PROPERTIES_PRICE"]=>
float(10)
["PROPERTIES_PERCENTAGE"]=>
int(0)
["PROPERTIES_BUYING"]=>
int(0)
["PROPERTIES_DISCOUNT"]=>
int(0)
["PROPERTIES_MORE"]=>
string(1) "0"
["COMPONENTS"]=>
array(0) {
}
["QUANTITY"]=>
int(11)
["TAX_FREE"]=>
string(1) "0"
["DISCOUNT"]=>
int(1)
["BUYING_PRICE"]=>
string(0) ""
["PRICE_EDIT"]=>
string(1) "0"
["PRICE"]=>
string(5) "10.00"
["CHECK_PRICE"]=>
float(20)
["MAX_ITEM_DISCOUNT"]=>
float(20)
["CART_PRICE"]=>
float(20)
}
[1]=>
array(23) {
["ITEM_ID"]=>
int(2331)
["ITEM_TYPE_ID"]=>
string(1) "1"
["CART_ITEM_ID"]=>
string(0) ""
["SAVED_TYPE_ID"]=>
string(0) ""
["ITEM_NAME"]=>
string(17) "TEST STOCK LEVELS"
["ERROR"]=>
string(0) ""
["PROPERTIES"]=>
array(1) {
[522]=>
array(1) {
[0]=>
string(4) "1123"
}
}
["PROPERTIES_INFO"]=>
array(1) {
[522]=>
array(12) {
["USAGE_TYPE"]=>
string(1) "1"
["CONTROL"]=>
string(7) "LISTBOX"
["TYPE"]=>
string(1) "1"
["NAME"]=>
string(11) "TEST OPTION"
["VALUES"]=>
array(1) {
[0]=>
string(4) "1123"
}
["REQUIRED"]=>
string(1) "1"
["PARENT_PROPERTY_ID"]=>
string(0) ""
["PARENT_VALUE_ID"]=>
string(0) ""
["TEXT"]=>
array(0) {
}
["CONTROL_PRICE"]=>
int(0)
["ORDER"]=>
string(1) "1"
["QUANTITY_ACTION"]=>
string(1) "1"
}
}
["PROPERTIES_PRICE"]=>
float(20)
["PROPERTIES_PERCENTAGE"]=>
int(0)
["PROPERTIES_BUYING"]=>
int(0)
["PROPERTIES_DISCOUNT"]=>
int(0)
["PROPERTIES_MORE"]=>
string(1) "0"
["COMPONENTS"]=>
array(0) {
}
["QUANTITY"]=>
int(5)
["TAX_FREE"]=>
string(1) "0"
["DISCOUNT"]=>
int(1)
["BUYING_PRICE"]=>
string(0) ""
["PRICE_EDIT"]=>
string(1) "0"
["PRICE"]=>
string(5) "10.00"
["CHECK_PRICE"]=>
float(30)
["MAX_ITEM_DISCOUNT"]=>
float(30)
["CART_PRICE"]=>
float(30)
}
}
Before looping this array, I receive some property_id (1123 for example).
I need to check if this property_id matches this element (1122 in my case)
["PROPERTIES"]=>
array(1) {
[522]=>
array(1) {
[0]=>
string(4) "1122"
}
}
then select its quantity property (in my case it is this element)
["QUANTITY"]=>
int(11)
The problem is to identify from which arrays select this property, because first I need to compare my received value with existing in array(1122 in my case).

I think you could do it faster with a better organized array. As it is I'll do a loop.
Something like that :
$quantity = 0;
$which_array = -1;
foreach($massive as $key=>$value){
if(isset($value['PROPERTIES_INFO'])){
$copy_properties = $value['PROPERTIES_INFO'];
$property_first = reset($copy_properties);
$id_property = key($property_first);
if($id_property == $what_id_you_are_looking_for){
$quantity = $value['QUANTITY'];//delete one of this
//or I don't know wich quantity you want so I put them both
$quantity = $value['PROPERTIES_INFO'][$id_property ]['QUANTITY_ACTION'];//delete one of this
$which_array = $key;
break;
}
}
}
