我的托管公司已禁用allow_url_fopen& allow_url_include。他们建议我使用cURL代替,然后我在simplexml上看到了这个补丁
$calendar = simplexml_load_file($source); with
if (ini_get('allow_url_fopen')) {
$calendar = simplexml_load_file($source);
}
else {
$ch = curl_init($source);
curl_setopt ($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$xml_raw = curl_exec($ch);
$calendar = simplexml_load_string($xml_raw); }
它适用于我的托管所以我想知道我是否可以在simplehtmldom上使用它这里是我正在使用的代码
<?php
include('simple_html_dom.php');
include ('phpQuery.php');
// Create DOM from URL
$html = file_get_html('http://www.urlhere.com/');
?>
我可以用这个吗?如果是,我应该做出哪些改变,谢谢你的帮助
编辑上面的代码
<?php
include('simple_html_dom.php');
include ('phpQuery.php');
if (ini_get('allow_url_fopen')) {
$html = file_get_html('http://www.weather.bm/'); }
else{ $ch = curl_init('http://www.weather.bm/');
curl_setopt ($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$src = curl_exec($ch);
$html = str_get_html($src, false);
var_dump($html); }
?>

您需要编辑simple_html_dom来源。它更容易创建自己的功能,完成原始功能。原件(由于allow_url_fopen而无法使用)是:
function file_get_html() {
$dom = new simple_html_dom;
$args = func_get_args();
@$dom->load(call_user_func_array('file_get_contents', $args), true);
if (($error=error_get_last())!==null)
throw new Exception($error['message']);
return $dom;
}
你可以这样做:
if (ini_get('allow_url_fopen')) {
$html = file_get_html('http://www.urlhere.com/');
}else{
$ch = curl_init('http://www.urlhere.com/');
curl_setopt ($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$src = curl_exec($ch);
$html = str_get_html($src, false);
}
无需修改源代码,并有效地做同样的事情。

另一种选择是使用data://
流包装器,它允许您在不改变它的情况下使用file_get_html()
功能。
if (!ini_get('allow_url_fopen')) {
$ch = curl_init($source);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$xml_raw = curl_exec($ch);
curl_close($ch);
$source = 'data://text/html;base64,'.base64_encode($xml_raw);
}
$html = file_get_html($source);
此方法使用PHP 5.2.0及更高版本支持的RFC 2397数据URL方案。
