PHP json array manipulation - php

Question

I have a JSON array like this:
{
result:{
customers:[
{
customer_id:16096,
customer_name:"test#test.test",
customer_login_name:"******",
customer_login_pwd:"*****",
customer_active:0,
customer_register_date:"2018-07-20 10:48:22",
customer_dashboard_email:"******",
customer_dashboard_pwd:"******",
used:"0.00",
name:"Trial",
price:0,
bandwidth:1,
start_date:"2018-07-20",
end_date:"2018-07-27",
package_is_active:1
},
{
customer_id:16648,
customer_name:"asd#asd.asd",
customer_login_name:"******",
customer_login_pwd:"********",
customer_active:1,
customer_register_date:"2018-08-08 17:24:16",
customer_dashboard_email:"******#*******.com",
customer_dashboard_pwd:"******",
used:"0.00",
name:"Trial",
price:0,
bandwidth:1,
start_date:"2018-08-08",
end_date:"2018-08-15",
package_is_active:1
},
{
customer_id:15271,
customer_name:"MarioRossiTEST",
customer_login_name:"mario#test.test",
customer_login_pwd:"*****",
customer_active:0,
customer_register_date:"2018-06-22 11:36:42",
customer_dashboard_email:"*****#******.com",
customer_dashboard_pwd:"*******",
used:"0.00",
name:"Trial",
price:0,
bandwidth:1,
start_date:"2018-06-22",
end_date:"2018-06-30",
package_is_active:0
},
]
}
}
Now in PHP i would like to provide the "customer_name" and retreive the "customer_id" of the same customer.
For example i provide "test#test.test" and i would like to get "16096".
Any way i could do this?

EDIT: After decoding the JSON array to PHP:
If you are doing this very often, I would suggest for looping through the array and creating a dictionary with the "customer_name" value as the key and the "customer_id", "customer_login_name", etc. in a dictionary that's the value to the "customer_name" key.
$customers_dic = {
"test#test.test"=> {
customer_id => 16096,
customer_login_name => "******",
customer_login_pwd =>"*****",
customer_active => 0,
customer_register_date => "2018-07-20 10:48:22",
customer_dashboard_email => "******",
customer_dashboard_pwd => "******",
used => "0.00",
name => "Trial",
price => 0,
bandwidth => 1,
start_date => "2018-07-20",
end_date => "2018-07-27",
package_is_active => 1
},
"asd#asd.asd" => {
customer_id => 16648,
customer_login_name => "******",
customer_login_pwd => "********",
customer_active => 1,
customer_register_date => "2018-08-08 17:24:16",
customer_dashboard_email => "******#*******.com",
customer_dashboard_pwd => "******",
used => "0.00",
name => "Trial",
price => 0,
bandwidth => 1,
start_date => "2018-08-08",
end_date => "2018-08-15",
package_is_active => 1
},
"mario#test.test" => {
customer_id => 15271,
customer_name => "MarioRossiTEST",
customer_login_pwd => "*****",
customer_active => 0,
customer_register_date => "2018-06-22 11:36:42",
customer_dashboard_email => "*****#******.com",
customer_dashboard_pwd => "*******",
used => "0.00",
name => "Trial",
price => 0,
bandwidth => 1,
start_date => "2018-06-22",
end_date => "2018-06-30",
package_is_active => 0
},
}
This way you can quickly access any "customer_id" by going $customers_dic["some#customer.name"]["customer_id"].
If you are just doing this a small number of times, you can just for loop through the customers array, keeping track of the index and checking if you have arrived on the desired customer's name.
$desired_customer_id;
for ($i = 0; $i < count($customers); $i++) {
if ($customers[$i]["customer_name"] === $desired_customer_name) {
$desired_customer_id = $customers[$i]["customer_id"];
}
}
You could also do this with a foreach instead; choice is up to you. :)

http://php.net/manual/en/function.json-decode.php
$arr = json_decode($json, true);
then you need to find your customer
array_filter($arr['result']['customers'], function ($customer) {
return ($customer['customer_name'] === 'test#test.test')
});
