php如何读取网页数据 php读取php文件内容( 二 )


?
$url = '';
$html = file_get_contents($url);
echo $html;
2. 用fopen打开url,以get方式获取内容
?
$url = '';
$fp = fopen($url, 'r');
stream_get_meta_data($fp);
$result = '';
while(!feof($fp))
{
$result .= fgets($fp, 1024);
}
echo "url body: $result";
fclose($fp);
3. 用file_get_contents函数,以post方式获取url
?
$data = https://www.04ip.com/post/array(
'foo'='bar',
'baz'='boom',
'site'='',
'name'='nowa magic');
$data = https://www.04ip.com/post/http_build_query($data);
//$postdata = https://www.04ip.com/post/http_build_query($data);
$options = array(
'http' = array(
'method' = 'POST',
'header' = 'Content-type:application/x-www-form-urlencoded',
'content' = $data
//'timeout' = 60 * 60 // 超时时间(单位:s)
)
);
$url = "";
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
echo $result;
4、使用curl库,使用curl库之前 , 可能需要查看一下php.ini是否已经打开了curl扩展
$url = '';
$ch = curl_init();
$timeout = 5;
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$file_contents = curl_exec($ch);
curl_close($ch);
echo $file_contents;
