这篇文章主要为大家详细介绍了PHP打开URL地址几种简单示例,具有一定的参考价值,可以用来参考一下。
感兴趣的小伙伴,下面一起跟随四海网的小编小韵来看看吧!
1: 用file_get_contents 以get方式获取内容代码如下:
<?php
$url='http://www.baidu.com/';
$html = file_get_contents($url);
//print_r($http_response_header);
ec($html);
printhr();
printarr($http_response_header);
printhr();
?>
代码如下:
<?
$fp = fopen($url, 'r');
printarr(stream_get_meta_data($fp));
printhr();
while(!feof($fp)) {
$result .= fgets($fp, 1024);
}
echo "url body: $result";
printhr();
fclose($fp);
?>
代码如下:
<?php
$data = array ('foo' => 'bar');
$data = http_build_query($data);
$opts = array (
'http' => array (
'method' => 'POST',
'header'=> "Content-type: application/x-www-form-urlencoded" .
"Content-Length: " . strlen($data) . "",
'content' => $data
),
);
$context = stream_context_create($opts);
$html = file_get_contents('http://localhost/e/admin/test.html', false, $context);
echo $html;
?>
代码如下:
<?
function get_url ($url,$cookie=false) {
$url = parse_url($url);
$query = $url[path]."?".$url[query];
ec("Query:".$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: $cookie\n";
$request.="";
fwrite($fp,$request);
while(!@feof($fp)) {
$result .= @fgets($fp, 1024);
}
fclose($fp);
return $result;
}
}
//获取url的html部分,去掉header
function GetUrlHTML($url,$cookie=false) {
$rowdata = get_url($url,$cookie);
if($rowdata)
{
$body= stristr($rowdata,"");
$body=substr($body,4,strlen($body));
return $body;
}
return false;
}
?>
代码如下:
<?
function HTTP_Post($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\n";
$request.="Host: ".$URL_Info["host"]."\n";
$request.="Referer: $referer\n";
$request.="Content-type: application/x-www-form-urlencoded\n";
$request.="Content-length: ".strlen($data_string)."\n";
$request.="Connection: close\n";
$request.="Cookie: $cookie\n";
$request.="\n";
$request.=$data_string."\n";
$fp = fsockopen($URL_Info["host"],$URL_Info["port"]);
fputs($fp, $request);
while(!feof($fp)) {
$result .= fgets($fp, 1024);
}
fclose($fp);
return $result;
}
printhr();
?>
代码如下:
<?
$ch = curl_init();
$timeout = 5;
curl_setopt ($ch, CURLOPT_URL, 'http://www.baidu.com/');
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$file_contents = curl_exec($ch);
curl_close($ch);
echo $file_contents;
?>
代码如下:
<?
function printarr(array $arr)
{
echo "<br> Row field count: ".count($arr)."<br>";
foreach($arr as $key=>$value)
{
echo "$key=$value <br>";
}
}
?>
代码如下:
< ?php
$file_contents = file_get_contents('http://www.ccvita.com/');
echo $file_contents;
?>
代码如下:
< ?php
$ch = curl_init();
$timeout = 5;
curl_setopt ($ch, CURLOPT_URL, 'http://www.ccvita.com');
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$file_contents = curl_exec($ch);
curl_close($ch);
echo $file_contents;
?>
代码如下:
< ?php
function vita_get_url_content($url) {
if(function_exists('file_get_contents')) {
$file_contents = file_get_contents($url);
} else {
$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);
}
return $file_contents;
}
?>
