Answer 1

これはあなたに考えを与えるはずです。しかし、json_encodeを呼び出す前に、マルチポートを使ってPHPで配列をソートする方が効果的です。

var arr = [ 
     {"id":"1498","tradingname":"Golden Shutter Photography1","listed":"2012-01-26 19:26:24","pictureurl":"","business_id":"1499","storeid":"1","phone":"6143737477","street":"122 Avebery Drive","suburb":"Berwick ","state":"1","postcode":"3806","discription":"","long":"","lat":"","offer":"200|60","tstamp":"2012-01-26 19:26:24","offers":"200|40"}, 
     {"id":"1499","tradingname":"Golden Shutter Photography2","listed":"2012-01-26 19:26:24","pictureurl":"","business_id":"1499","storeid":"1","phone":"6143737477","street":"122 Avebery Drive","suburb":"Berwick ","state":"1","postcode":"3806","discription":"","long":"","lat":"","offer":"400|50","tstamp":"2012-01-26 19:26:24","offers":"200|50"}, 
     {"id":"1500","tradingname":"Golden Shutter Photography3","listed":"2012-01-26 19:26:24","pictureurl":"","business_id":"1499","storeid":"1","phone":"6143737477","street":"122 Avebery Drive","suburb":"Berwick ","state":"1","postcode":"3806","discription":"","long":"","lat":"","offer":"200|50","tstamp":"2012-01-26 19:26:24","offers":"400|50"} 
    ]; 


    function sortbyoffer(a,b) { 
     var aa = a.offer.split("|"); 
     var bb = b.offer.split("|"); 
     if(aa[0] == bb[0]) { 
     return aa[1] - bb[1]; 
     } else { 
     return aa[0] - bb[0]; 
     } 
    } 

    arr.sort(sortbyoffer); 

    for(var n=0;n<arr.length;n++){ 
     document.write(arr[n].id + ' ' + arr[n].tradingname + ' ' + arr[n].offer + '<br>'); 
    } 

出力は次のようになります。

1500 Golden Shutter Photography3 200|50 
1498 Golden Shutter Photography1 200|60 
1499 Golden Shutter Photography2 400|50
