Parse a string with PHP

Question

I keep product options as string in DB, and I need to parse it (string to array).

String is:

{option_name:option_id{variant_id:variant_name}}

How can I parse it with using PHP?

It looks like a JSON string. Why not just use json_decode()? — bcosca

Why not use serialize() and unserialize()?

Instead of converting your product to the string you have above, take the product (I'm assuming it's an array) and then serialize it serialize($myproductarray). That turns it into a portable string. When you need the info from the database, get the string, and unserialize($myproductstring) to get it back into an array.

You didn't detail the field formats so here's a guestimate that you can tweak:

preg_match('/^{(\w+):(\d+){(\d+):(\w+)}}$/', '{an_option_name:123{456:a_variant_name}}', $matches); $option_name = $matches[1]; $option_id = $matches[2]; $variant_id = $matches[3]; $variant_name = $matches[4];
