Splitting string into an array in PHP

[aenleague]

I want split a string which consists of products. Each product is encloded within {..}, and separated by comma. For instance, I have a strin below.\[code\][{\"productid\" : \"prod:kj42j3d24-47c2-234lkj2-e3c2-cfc9a4a3b005\",\"memo\" : \"product description\",\"taxable\" : 0,\"unitweight\" : 0,\"unitcost\" : 0,\"unitprice\" : 12.34,\"quantity\" : 1.00},{\"productid\" : \"prod:k324jl-462d-e589-aecf-32k4j\",\"memo\" : \"prodict description\",\"taxable\" : 0,\"unitweight\" : 0,\"unitcost\" : 0,\"unitprice\" : 12.23,\"quantity\" : 1}]\[/code\]and want to separate each product into different indexes of an array. Thanks.
