How to retrieve certain data in string? - php

Question

Hello may i know how to retrieve data in string?
$url = 'test url';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$info = curl_getinfo($ch);
$response = curl_exec($ch);
curl_close ($ch);
echo 'Response: ';
echo gettype($response);
echo '<br>';
echo($response);
Output :
Response: string
TRANSACTION_ID=abc123
MERCHANT_ACC_NO=M213213
TXN_STATUS=A
TRAN_DATE=2020-07-20
CAPTURE_DATE=2020-07-20
SALES_DATE=2020-07-20
RESPONSE_CODE=1
RESPONSE_MESSAGE=Success
As you can see the output of the code is as shown above. This is my first time to encounter this kind of output because usually I get json as the output. So my question is may I know how to retrieve the RESPONSE_MESSAGE in the output or may I know how to convert the output to array or json so that I can easily retrieve the data. Sorry for asking this I'm quite new with this PHP and CURL function.

You can explode to lines and explode the lines to parts in a foreach.
Edit: I realized the "Response:" was actually outputted manually.
Changed the code to slice the array from second item instead.
foreach(array_slice(explode("\n", $str), 1) as $line){
$temp = explode("=", $line);
$res[$temp[0]] = $temp[1];
}
Output:
array(8) {
["TRANSACTION_ID"]=>
string(6) "abc123"
["MERCHANT_ACC_NO"]=>
string(7) "M213213"
["TXN_STATUS"]=>
string(1) "A"
["TRAN_DATE"]=>
string(10) "2020-07-20"
["CAPTURE_DATE"]=>
string(10) "2020-07-20"
["SALES_DATE"]=>
string(11) "2020-07-20 "
["RESPONSE_CODE"]=>
string(1) "1"
["RESPONSE_MESSAGE"]=>
string(7) "Success"
}
