PHP开源脚本语言
PHP(外文名: Hypertext Preprocessor,中文名:“超文本预处理器”)是一种通用开源脚本语言。语法吸收了C语言、Java和Perl的特点,入门门槛较低,易于学习,使用广泛,主要适用于Web开发领域。PHP的文件后缀名为php。
本文为大家列举了php发送post请求的三种方法讲解,分别使用curl、file_get_content、fsocket来实现post提交数据 感兴趣的同学参考下.
public static function post($url, $post_data = '', $timeout = 5){//curl
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_POST, 1);
if($post_data != ''){
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
}
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
curl_setopt($ch, CURLOPT_HEADER, false);
$file_contents = curl_exec($ch);
curl_close($ch);
return $file_contents;
}
public static function post2($url, $data){//file_get_content
$postdata = http_build_query(
$data
);
$opts = array('http' =>
array(
'method' => 'POST',
'header' => 'Content-type: application/x-www-form-urlencoded',
'content' => $postdata
)
);
$context = stream_context_create($opts);
$result = file_get_contents($url, false, $context);
return $result;
}
public static function post3($host,$path,$query,$others=''){//fsocket
$post="POST $path HTTP/1.1rnHost: $hostrn";
$post.="Content-type: application/x-www-form-";
$post.="urlencodedrn${others}";
$post.="User-Agent: Mozilla 4.0rnContent-length: ";
$post.=strlen($query)."rnConnection: closernrn$query";
$h=fsockopen($host,80);
fwrite($h,$post);
for($a=0,$r='';!$a;){
$b=fread($h,8192);
$r.=$b;
$a=(($b=='')?1:0);
}
fclose($h);
return $r;
}
}
