- 方法1: 用 file_get_contents 以get方式獲取內容：
<?php
$url = 'https://wenda.shukaiming.com/';
echo file_get_contents($url);
?>
- 方法2: 用fopen打開url, 以get方式獲取內容：
<?php
//r標識read，即標識只讀
$fp = fopen($url, 'r');
stream_get_meta_data($fp);
while (!feof($fp)) {
$body.= fgets($fp, 1024);
}
echo $body;
fclose($fp);
?>
- 方法3：用 file_get_contents函數,以post方式獲取url
<?php
$data = array(‘foo' => ‘bar');
$data = http_build_query($data);
$opts = array('http' => array('method' => 'POST', 'header' => 'Content-type: application/x-www-form-urlencodedrn' . 'Content-Length: ' . strlen($data) . '
', 'content' => $data));
$context = stream_context_create($opts);
$html = file_get_contents('https://wenda.shukaming.com', false, $context);
echo $html;
?>
- 方法4：用fsockopen函數打開url，以get方式獲取完整的數據，包括header和body,fsockopen需要 PHP.ini 中 allow_url_fopen 選項開啟
<?php
function get_url($url, $cookie = false) {
$url = parse_url($url);
$query = $url[path] . ” ? ” . $url[query];
echo $query;
$fp = fsockopen($url[host], $url[port] ? $url[port] : 80, $errno, $errstr, 30);
if (!$fp) {
return false;
} else {
$request = "GET $query HTTP/1.1
";
$request.= "Host: $url[host]
";
$request.= "Connection: Close
";
if ($cookie) $request.= "Cookie: $cookien";
$request.= "
";
fwrite($fp, $request);
while (!@feof($fp)) {
$result.= @fgets($fp, 1024);
}
fclose($fp);
return $result;
}
}
//獲取url的html部分，去掉header
function GetUrlHTML($url, $cookie = false) {
$rowdata = get_url($url, $cookie);
if ($rowdata) {
$body = stristr($rowdata, ”rnrn”);
$body = substr($body, 4, strlen($body));
return $body;
}
return false;
}
?>
- 方法5：用fsockopen函數打開url，以POST方式獲取完整的數據，包括header和body
<?php
function HTTP_Post($URL, $data, $cookie, $referrer = "") {
// parsing the given URL
$URL_Info = parse_url($URL);
// Building referrer
if ($referrer == "") // if not given use this script as referrer
$referrer = "111";
// making string from $data
foreach ($data as $key => $value) $values[] = "$key=" . urlencode($value);
$data_string = implode("&", $values);
// Find out which port is needed – if not given use standard (=80)
if (!isset($URL_Info["port"])) $URL_Info["port"] = 80;
// building POST-request:
$request.= "POST " . $URL_Info["path"] . " HTTP/1.1
";
$request.= "Host: " . $URL_Info["host"] . "
";
$request.= "Referer: $referer
";
$request.= "Content-type: application/x-www-form-urlencodedn";
$request.= "Content-length: " . strlen($data_string) . "
";
$request.= "Connection: closen";
$request.= "Cookie: $cookien";
$request.= "
";
$request.= $data_string . "
";
$fp = fsockopen($URL_Info["host"], $URL_Info["port"]);
fputs($fp, $request);
while (!feof($fp)) {
$result.= fgets($fp, 1024);
}
fclose($fp);
return $result;
}
?>
- 方法6:使用curl庫，使用curl庫之前，可能需要查看一下php.ini是否已經打開了curl擴展
<?php $ch = curl_init(); $timeout = 5; curl_setopt($ch, CURLOPT_URL, 'http://wenda.shukaiming.com'); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout); $file_contents = curl_exec($ch); curl_close($ch); echo $file_contents; ?>
