Get the values of an associative array into variables that are in string format from cookies.
I am getting these associative array type values from a cookie, which is in string format -
[{"id":"7","quantity":"3","price":1500,"title":"Shoes"},{"id":"9","quantity":"4","price":1290,"title":"Shirt"}]
var_dump($getcart); // return of this is(just to confirm) -
string(111) "[{"id":"7","quantity":"3","price":1500,"title":"Shoes"},{"id":"9","quantity":"4","price":1290,"title":"Shirt"}]"
If I convert this to an array with
json_encode($getcart);
taking this into another array for further operations with
$ar=array();
$ar = json_decode($getcart);
I need help -
Retrieving all values by its "id". Ex. If I search for id = 7 I need to get its values = 3 and price-1500 and title shoes
I have tried and failed here -
for($i=0;$i<sizeof($ar);$i++)
{
print_r(array_values($ar[1])); // gives back ----> Array ( [0] => stdClass Object ( [id] => 7 [quantity] => 3 [price] => 1500 [title] => casual blue strip ) [1] => stdClass Object ( [id] => 9 [quantity] => 4 [price] => 1290 [title] => United Colors of Benetton shirt ) ) Array ( [0] => stdClass Object ( [id] => 7 [quantity] => 3 [price] => 1500 [title] => casual blue strip ) [1] => stdClass Object ( [id] => 9 [quantity] => 4 [price] => 1290 [title] => United Colors of Benetton shirt ) )
}
echo $ar // gives ------> ArrayArray
which are valid but not what I want. Any help here for getting the values separately?

Use json_decode($getcart, true);
. Here the parameter true
in json_decode () converts JSON
to an array. Without a parameter, true
it is converted to array()
from object
.
$getcart = '[{"id":"7","quantity":"3","price":1500,"title":"Shoes"},{"id":"9","quantity":"4","price":1290,"title":"Shirt"}]';
$arr = json_decode($getcart, true);
print '<pre>';
foreach($arr as $val){
print_r($val);
//print $val['id'];
//print $val['quantity'];
//print $val['price'];
//print $val['title'];
}
print '</pre>';
