Convert string into single array, PHP - php

Question

I am working in a Laravel project. I want to convert a string into single array in efficient way.
String is
$string = txn_status=0|txn_msg=success|txn_err_msg=NA|clnt_txn_ref=969239|tpsl_bank_cd=470|tpsl_txn_id=192630337|txn_amt=1.00|clnt_rqst_meta={itc:NIC~TXN0001~122333~rt14154~8 mar 2014~Payment~forpayment}{custname:test}|tpsl_txn_time=26-12-2015 15:56:20|tpsl_rfnd_id=NA|bal_amt=NA|rqst_token=hdfs-df-jkfhskjfhsjkd|hash=jhdsfs54367jhf,
And I want output look like below format. It is a json format:-
[ txn_status: "0",
txn_msg : "success",
txn_err_msg: "NA",
.
.
.
hash: "XYZ" ]

Answer 1

You can split as like that try this:
$string = "txn_status=0|txn_msg=success|txn_err_msg=NA|clnt_txn_ref=969239|tpsl_bank_cd=470|tpsl_txn_id=192630337|txn_amt=1.00|clnt_rqst_meta={itc:NIC~TXN0001~122333~rt14154~8 mar 2014~Payment~forpayment}{custname:test}|tpsl_txn_time=26-12-2015 15:56:20|tpsl_rfnd_id=NA|bal_amt=NA|rqst_token=hdfs-df-jkfhskjfhsjkd|hash=jhdsfs54367jhf";
$firstArray = explode("|", $string);
foreach ($firstArray as $key => $value) {
$newArr = explode("=", $value);
$myRequiredArr[$newArr[0]] = $newArr[1];
}
echo "<pre>"; // just for formatting
print_r($myRequiredArr); // print your result
Result is:
Array
(
[txn_status] => 0
[txn_msg] => success
[txn_err_msg] => NA
[clnt_txn_ref] => 969239
[tpsl_bank_cd] => 470
[tpsl_txn_id] => 192630337
[txn_amt] => 1.00
[clnt_rqst_meta] => {itc:NIC~TXN0001~122333~rt14154~8 mar 2014~Payment~forpayment}{custname:test}
[tpsl_txn_time] => 26-12-2015 15:56:20
[tpsl_rfnd_id] => NA
[bal_amt] => NA
[rqst_token] => hdfs-df-jkfhskjfhsjkd
[hash] => jhdsfs54367jhf
)

You could use the preg_match_all in conjunction with the array_combine like this:
$string = "txn_status=0|txn_msg=success|txn_err_msg=NA|clnt_txn_ref=969239|tpsl_bank_cd=470|tpsl_txn_id=192630337|txn_amt=1.00|clnt_rqst_meta={itc:NIC~TXN0001~122333~rt14154~8 mar 2014~Payment~forpayment}{custname:test}|tpsl_txn_time=26-12-2015 15:56:20|tpsl_rfnd_id=NA|bal_amt=NA|rqst_token=hdfs-df-jkfhskjfhsjkd|hash=jhdsfs54367jhf";
preg_match_all("/([^|]+)=([^|]+)/", $string, $array);
$output = array_combine($array[1], $array[2]);
echo json_encode($output, JSON_PRETTY_PRINT);

Or the preg_split like this:
$array = preg_split("/[|=]/", $string);
$output = [];
for ($i=0; $i<count($array); $i++) {
$output[$array[$i]] = $array[++$i];
}

Or a simplified version of #devpro's code:
$array = explode("|", $string);
$output = [];
foreach ($array as $v) {
list($key, $value) = explode("=", $v);
$output[$key] = $value;
}

You can use the combination of php functions explode , array_map and call_user_func_array like as
$string = "txn_status=0|txn_msg=success|txn_err_msg=NA|clnt_txn_ref=969239|tpsl_bank_cd=470|tpsl_txn_id=192630337|txn_amt=1.00|clnt_rqst_meta={itc:NIC~TXN0001~122333~rt14154~8 mar 2014~Payment~forpayment}{custname:test}|tpsl_txn_time=26-12-2015 15:56:20|tpsl_rfnd_id=NA|bal_amt=NA|rqst_token=hdfs-df-jkfhskjfhsjkd|hash=jhdsfs54367jhf";
$arr = array();
array_map(function($v)use(&$arr){ $a = explode("=",$v); return $arr[$a[0]] = $a[1];},explode('|',$string));
print_r($arr);
