PHP 5.2 才有支源 json_encode()

5.2以下會顯示下列錯誤

PHP Fatal error:  Call to undefined function json_encode()

可在PHP中加入下列function即可使用json_encode()

語法主要先檢查是否有json_encode這個function
如果沒有(php無支援)就使用下列function產生json格式字串

//PHP 5.1.x 不支援 json_encode()
if ( !function_exists(‘json_encode’) ){
function json_encode($data)
