Question

Array Values to assign the variables in php:
Array
(
[0] => stdClass Object
(
[Id] => 116249
[Amount] => 51.62
[Currency] => INR
[ExchangeRate] => 1
[InvoiceDate] => 2015-12-16T00:00:00Z
}
[1] => stdClass Object
(
[Id] => 116250
[Amount] => 55.20
[Currency] => KWD
[ExchangeRate] => 1
[InvoiceDate] => 2015-12-16T00:00:00Z
}
[2] => stdClass Object
(
[Id] => 116251
[Amount] => 59.42
[Currency] => USD
[ExchangeRate] => 1
[InvoiceDate] => 2015-12-16T00:00:00Z
}
}
foreach ($invoice as $key => $value)
{
$Id=$value->Id;
$Amount=$value->Amount;
$Currency=$value->Currency;
$ExchangeRate=$value->ExchangeRate;
$invoiceDate = str_replace('Z', '', str_replace('T', ' ',$value->InvoiceDate));
}
$jsonData ='[{"Id": "'.$Id.'",
"Amount": "'.$Amount.'",
"Currency": "'.$Currency.'",
"ExchangeRate": "'.$ExchangeRate.'",
"invoiceDate": "'.$invoiceDate.'"}];
I tried this code last array values only print array[2] values, I need Output like
[{"Id": "116249",
"Amount": "51.62",
"Currency": "INR",
"ExchangeRate": "1",
"invoiceDate": "2015-12-16T00:00:00Z"},
{"Id": "116250",
"Amount": "55.20",
"Currency": "KWD",
"ExchangeRate": "1",
"invoiceDate": "2015-12-16T00:00:00Z"},
{"Id": "116251",
"Amount": "59.42",
"Currency": "USD",
"ExchangeRate": "1",
"invoiceDate": "2015-12-16T00:00:00Z"}]

Answer 1

I agree with Liam that json_encode() is probably the best solution for your issue. However, if you are looking for a DIY solution, it's pretty simple:
$jsonData = '[';
foreach ($invoice as $key => $value)
{
$Id=$value->Id;
$Amount=$value->Amount;
$Currency=$value->Currency;
$ExchangeRate=$value->ExchangeRate;
$invoiceDate = str_replace('Z', '', str_replace('T', ' ',$value->InvoiceDate));
// Append the next invoice's JSON data to all of the JSON data
$jsonData .='{"Id": "'.$Id.'",
"Amount": "'.$Amount.'",
"Currency": "'.$Currency.'",
"ExchangeRate": "'.$ExchangeRate.'",
"invoiceDate": "'.$invoiceDate.'"},';
}
// Clean up and close off the JSON data:
$jsonData = rtrim($jsonData, ','); // remove the trailing comma
$jsonData .= ']'; // Add the closing bracket.
The issue you were having in your code was that you were only assigning the JSON data once, after the foreach loop ran. Instead, you would need to append each invoice's JSON data with the other invoices' JSON data.
Nonetheless, json_encode() is probably the better solution because it's one line, easier to read, and arguably easier to understand.

Answer 2

Your wanting to create a json string from an array. All you need to do is run the following
jsonData = json_encode($invoice);
If your wanting to create the array using a loop to generate specific values only then you can do the following:
$tmp = array();
foreach ($invoice as $key => $value)
{
$tmp["id"] = $value->Id;
$tmp["amount"] = $value->Amount;
$tmp["Currency"] = $value->Currency;
$tmp["ExchangeRate"] = $value->ExchangeRate;
$tmp["invoiceDate"] = str_replace('Z', '', str_replace('T','',$value->InvoiceDate));
}
jsonData = json_encode($tmp);
* Edit *
If your using a mysql date for the invoiceData variable. Then you would be better to use the PHP date function.
