基本上这是一个搜索栏和我走的搜索项,并把它的API调用的网址,但我越来越未能加载外部实体“”
警告:使用simplexml_load_file()函数.simplexml-load-file]:I/O警告:未能加载外部实体“”
有什么想法?
代码:
if (!empty($_POST['searchbird'])){
$searchbird=rawurlencode($_POST['searchbird']);
$searchCode = "http://ebird.org/ws1.1/data/obs/region_spp/recent?rtype=subnational2&r=US-AZ-013&sci=$searchbird";
$url_headers = @get_headers($searchCode);
if($url_headers[0] == 'HTTP/1.1 200 OK') {
$xml = simplexml_load_file($url);
print_r($xml);
} else {
// Error
echo $searchCode;
print_r($url_headers);
exit("failed to load XML");
}
} else {
$searchbird = '';
$form = "<form method='post'>
<strong>Enter the name of a Bird</strong>
<input type='text' name='searchbird' value='$searchbird' />
<input type='submit' name='submit' value='submit' />
</form>";
echo $form;
}
你在哪里定义'$ url'? –
您的网址为空或为空;你在哪里设置它? – Ibu
在你的配置中,你看着allow_url_fopen –
