请尝试下面的代码

$URL = "http://103.5.126.24/PalmHallServer/coodraw/coodraw!queryAllProduct.action";

$content = file_get_contents($URL);    // get json data using file_get_content
$content_arr = json_decode($content); // json data to php array.

或者如果你想使用 curl

$s = curl_init(); 
curl_setopt($s,CURLOPT_URL,$this->_url);
curl_setopt($s,CURLOPT_RETURNTRANSFER,true);    
$result = curl_exec($s);
curl_close($s);
$content_arr = json_decode($result); // json data to php array.

然后您可以 print_r($content_arr) 并检查“LuckDrawProductList”密钥或访问 $content_arr['LuckDrawProductList][0]
