Apex code result as normal json

Hi!
I wrote Apex class:

@RestResource(urlMapping='/show/*')
global with sharing class User{
@HttpGet global static string doGet(){
    Map < String, String > FieldMetaData = new Map< String, String >();
    FieldMetaData.put('type', 'string');
    FieldMetaData.put('label', 'label name');
    FieldMetaData.put('name', 'first name');
    FieldMetaData.put('length', '20');
    String FieldMetaDataResult = JSON.serialize(FieldMetaData);
    return FieldMetaDataResult ;
}
}

when I call it from php script the result is:
"{\"type\":\"string\",\"label\":\"label name\",\"length\":\"20\",\"name\":\"first name\"}"
How can I return result without slashes and double quotes? I need a normal json, namely:
{"type":"string","label":"label name","length":"20","name":"first name"}
Thank you!

Hi 

Below is corrected code 

@RestResource(urlMapping='/show/*')
global with sharing class User{
    @HttpGet global static Map < String, String > doGet(){ // change return type from string to Map<string,string> 
        Map < String, String > FieldMetaData = new Map< String, String >();
        FieldMetaData.put('type', 'string');
        FieldMetaData.put('label', 'label name');
        FieldMetaData.put('name', 'first name');
        FieldMetaData.put('length', '20');
        //String FieldMetaDataResult = JSON.serialize(FieldMetaData);// no need to serialize to string.
        return FieldMetaData; // return Map it will return required clean json.
    }
}

I did code this way and its working fine for us.
