I'm really have no idea about regex...
So I got stuck... Can anyone give me a solution with explanation of regex itself?
Here is my code:
$str = "id:521082299088|name:JOHNSON GREIG DENOIA|mounth:JAN17|amount:170027|admin:2500|billqty:1|metre:R1/900|usage:00010261-00010550|reffno:0BKP21851AF3EC2E0D4F56997EA19DFA|charge:170377|balace:1935";
$pregsplit = preg_split("/[\s|]+/",$string2);
Output:
Array
(
[0] => id:521082299088
[1] => name:JOHNSON
[2] => GREIG
[3] => DENOIA
[4] => mounth:JAN17
[5] => amount:170027
[6] => admin:2500
[7] => billqty:1
[8] => metre:R1/900
[9] => usage:00010261-00010550
[10] => reffno:0BKP21851AF3EC2E0D4F56997EA19DFA
[11] => charge:170377
[12] => balance:1935
)
I want output like this:
Array
(
"id" => 521082299088
"name" => "JOHNSON GREIG DENOIA"
"mount" => "JAN17"
"amount" => 170027
"admin" => 2500
"billqty" => 1
"metre" => "R1/900"
"usage" => "00010261-00010550"
"reffno" => "0BKP21851AF3EC2E0D4F56997EA19DFA"
"charge" => 170377
"balance" => 1935
)

Answer 1

1) The solution using preg_match_all function with specific regex pattern:
$str = "id:521082299088|name:JOHNSON GREIG DENOIA|mounth:JAN17|amount:170027|admin:2500|billqty:1|metre:R1/900|usage:00010261-00010550|reffno:0BKP21851AF3EC2E0D4F56997EA19DFA|charge:170377|balace:1935";
preg_match_all("/(\w+):([^|]+)/", $str, $matches, PREG_SET_ORDER);
$result = [];
foreach ($matches as $items) {
$result[$items[1]] = $items[2];
}
// $items[1] contains a "parameter" name captured by the first capturing group (\w+)
// $items[2] contains a "parameter" value captured by the second capturing group ([^|]+)
print_r($result);
The output:
Array
(
[id] => 521082299088
[name] => JOHNSON GREIG DENOIA
[mounth] => JAN17
[amount] => 170027
[admin] => 2500
[billqty] => 1
[metre] => R1/900
[usage] => 00010261-00010550
[reffno] => 0BKP21851AF3EC2E0D4F56997EA19DFA
[charge] => 170377
[balace] => 1935
)
(\w+) - matches all alphanumeric characters followed by :
([^|]+) - matches all characters excepting | which is delimiter
http://php.net/manual/en/function.preg-match-all.php
2) In addition to the first approach - using array_combine function(to combine all respective values from two capturing groups):
preg_match_all("/(\w+):([^|]+)/", $str, $matches);
$result = array_combine($matches[1], $matches[2]);
// will give the same result
3) The third alternative approach would be using explode() function:
$result = [];
foreach (explode("|", $str) as $items) {
$pair = explode(":", $items);
$result[$pair[0]] = $pair[1];
}

Answer 2

If you are unable to write regular expression.Here is a simple solution using explode() method.The explode() function breaks a string into an array.
<?php
$str = "id:521082299088|name:JOHNSON GREIG DENOIA|mounth:JAN17|amount:170027|admin:2500|billqty:1|metre:R1/900|usage:00010261-00010550|reffno:0BKP21851AF3EC2E0D4F56997EA19DFA|charge:170377|balace:1935";
$array = explode('|',$str);
foreach($array as $key=>$value){
$data = explode(':',$value);
$final[$data[0]] = $data[1];
}
print_r($final);
?>
Output:
Array
(
[id] => 521082299088
[name] => JOHNSON GREIG DENOIA
[mounth] => JAN17
[amount] => 170027
[admin] => 2500
[billqty] => 1
[metre] => R1/900
[usage] => 00010261-00010550
[reffno] => 0BKP21851AF3EC2E0D4F56997EA19DFA
[charge] => 170377
[balace] => 1935
)

A funny way (only if your string doesn't contain = or &): translate pipes to ampersands and colons to equal signs, then parse it as an URL query with parse_str:
$str = "id:521082299088|name:JOHNSON GREIG DENOIA|mounth:JAN17|amount:170027|admin:2500|billqty:1|metre:R1/900|usage:00010261-00010550|reffno:0BKP21851AF3EC2E0D4F56997EA19DFA|charge:170377|balace:1935";
parse_str(strtr($str, ':|', '=&'), $result);
print_r($result);

This approach would be an alternative.
You can separate string and create an array from it using PHP's explode() function. Then you can separate the 'key:value' structure using strpos() and substr() functions.
// input string
$str = "id:521082299088|name:JOHNSON GREIG DENOIA|mounth:JAN17|amount:170027|admin:2500|billqty:1|metre:R1/900|usage:00010261-00010550|reffno:0BKP21851AF3EC2E0D4F56997EA19DFA|charge:170377|balace:1935";
// make an array out of the string, split elements on each pipe character ('|')
$arr = explode('|', $str);
// create an output array to keep the results
$output = [];
// process the array
foreach ($arr as $item) {
// get delimiter
$separatorPos = strpos($item, ':');
// take the key part (The part before the ':')
$key = substr($item, 0, $separatorPos);
// take the value part (The part after the ':')
$value = substr($item, $separatorPos);
// push it into the output array
$output[$key] = $value;
}
// dump the output array
var_export($output);
Dump of the output array would be like follwing;
[
'id' => ':521082299088',
'name' => ':JOHNSON GREIG DENOIA',
'mounth' => ':JAN17',
'amount' => ':170027',
'admin' => ':2500',
'billqty' => ':1',
'metre' => ':R1/900',
'usage' => ':00010261-00010550',
'reffno' => ':0BKP21851AF3EC2E0D4F56997EA19DFA',
'charge' => ':170377',
'balace' => ':1935',
]
