与javascript一样,我们使用< script defer =“defer”>< / script>.有没有办法用PHP代码做同样的事情？

更新：
这是我使用的代码：

信息：此代码位于我的侧边栏中,导致网站在加载时停止2-3秒.我正试图跳过这个问题,并在网站的其余部分加载时加载此代码….我也开放其他编码解决方案.

<div style="padding:5px;">
<?PHP
function currency($From_Currency,$to_Currency,$amount) {
$amount = urlencode($amount);
$from_Currency = urlencode($from_Currency);
$to_Currency = urlencode($to_Currency);
$url = "http://www.GOOGLE.COM/ig/calculator?hl=en&amp;q=$amount$from_Currency=?$to_Currency";
$ch = curl_init();
$timeout = 0;
curl_setopt ($ch,CURLOPT_URL,$url);
curl_setopt ($ch,CURLOPT_RETURNtransfer,1);
curl_setopt ($ch,CURLOPT_USERAGENT,"Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1)");
curl_setopt ($ch,CURLOPT_CONNECTTIMEOUT,$timeout);
$rawdata = curl_exec($ch);
curl_close($ch);
$data = explode('"',$rawdata);
$data = explode('"',$data['3']);
$VAR = $data['0'];
return round($var,1);
}
?>
