how to explode following string - php

Question

How do i explode a following string
$str = "ProductId=123, Name=Ancient Roots, Modern Pursuits, Country=India, City=Bangalore, Price=3368"
Such that output array will contain
[
"ProductId" => "123",
"Name" => "Ancient Roots, Modern Pursuits",
"Country" => "India",
"City" => "Bangalore",
"Price" => "3368"
]
I tried to explode by "comma", then each element again explode by "equal to" as.
$arr = explode(",", $str);
and again
$prodarr = explode("=", $arr[0]);
$product["ProductId"] = $prodarr[1]
But facing problem when another comma is exist in value like in name "Ancient Roots, Modern Pursuits"

Answer 1

Your structure is very weak for breaking. But you can still try to parse it.
First explode on =. You will have next key and current value.
Then loop these and explode on , and select last element for next key and all previous parts as value (sample):
<?php
$str = "ProductId=123, Name=Ancient Roots, Modern Pursuits, Country=India, City=Bangalore, Price=3368";
$chunks = explode('=', $str);
$keys = [];
$values = [];
foreach ($chunks as $i => $chunk) {
$parts = explode(',', $chunk);
if ($i != count($chunks) - 1) {
$keys[] = trim(array_pop($parts));
}
if ($i != 0) {
$values[] = implode(',', $parts);
}
}
var_dump(array_combine($keys, $values));

I played a little bit around. I used preg_match_all() to extract the Patterns which contain characters that are no , and no = followed by a = followed by characters that are no = followed by a , or end of line. here is the result:
$result = array();
preg_match_all('/([^=,]+=[^=]+)(,|$)/', $string, $matches);
foreach($matches[1] as $data){
$data = explode('=', $data);
$result[trim($data[0])] = trim($data[1]);
}
$result = json_encode($result);
The result is:
{"ProductId":"123","Name":"Ancient Roots, Modern Pursuits","Country":"India","City":"Bangalore"}

Try something like this
<?php
$str = "ProductId=123, Name=Ancient Roots, Modern Pursuits, Country=India, City=Bangalore, Price=3368";
$str_arr = explode(",", $str);
$json_array = array();
for ($i = 0; $i < sizeof($str_arr); $i++)
{
if (isset($str_arr[$i + 1]))
{
if (strpos($str_arr[$i + 1], '=') !== false)
{
$prod = explode("=", $str_arr[$i]);
$json_array["" . $prod[0] . ""] = "" . $prod[1] . "";
}
else
{
$textAppend = "," . $str_arr[$i + 1];
$prod = explode("=", $str_arr[$i]);
$json_array["" . $prod[0] . ""] = "" . $prod[1] . "" . $textAppend . "";
$i++;
}
}
else
{
$prod = explode("=", $str_arr[$i]);
$json_array["" . $prod[0] . ""] = "" . $prod[1] . "";
}
}
var_dump($json_array);
?>
