Parse a string with key=value declarations and make an associative array

Question

How do I explode the following string:

$str = "ProductId=123, Name=Ancient Roots, Modern Pursuits, Country=India, City=Bangalore, Price=3368"

Such that the 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 I'm facing the problem when another comma exists in a value like in name Ancient Roots, Modern Pursuits.

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));
