分享两段PHP代码，超实用POST和GET

/* 公用函数 */
if (!function_exists("do_post")){
function do_post($url, $data){
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_URL, $url);
$ret = curl_exec($ch);

curl_close($ch);
return $ret;
}
}
if(!function_exists("get_url_contents")){
function get_url_contents($url){
if (ini_get("allow_url_fopen") == "1")
return file_get_contents($url);

$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_URL, $url);
$result =  curl_exec($ch);
curl_close($ch);

return $result;
}
}
