How to use PHP to make a fuzzy query for MongoDB (Chinese in query criteria)

How to use PHP to fuzzy query MongoDB (query criteria in Chinese)?
There are two data in the known MongoDB:
{"BC": "012345678", "name": "The rhyme of Vinda tissue Flower", "CLS": "Commodity", "num": "100"}

{"BC": "12345678", "name": "Vinda paper Towel", "CLS": "Commodity", "num": "10"}

How to use PHP to fuzzy query, such as query name contains "Vinda" record, then all two records returned.

Which one helps to write a function, the incoming parameter is a string (such as "Vinda"), the return value is an array of arrays. Thank you.
