我的托管公司已禁用allow_url_fopen 和allow_url_include。他们建议我改用 cURL,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); }
它可以在我的主机上运行,所以我想知道我是否可以在 simplehtmldom 上使用它,这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?如果是的话我应该做什么改变,谢谢你的帮助
编辑以上代码
<?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); }
?>

最佳答案
您需要编辑 simple_html_dom 源。创建自己的函数来完成原始函数的功能会更容易。原始的(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,并且有效地执行相同的操作。
