PHP的curl實現get和post

類似於dreamhost這類主機服務商，是顯示fopen的使用的。使用PHP的curl可以實現支持FTP、FTPS、HTTP HTPPS SCP SFTP TFTP TELNET DICT FILE和LDAP。curl 支持SSL證書、HTTP POST、HTTP PUT 、FTP 上傳，kerberos、基於HTT格式的上傳、代理、cookIE、用戶＋口令證明、文件傳送恢復、http代理通道就最常用的來說，是基於http的GET和post方法。

代碼實現：

1、http的get實現
$ch = curl_init("http://www.jzxue.com/") ;
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true) ;
curl_setopt($ch, CURLOPT_BINARYTRANSFER, true) ;
$output = curl_exec($ch) ;
$fh = fopen("out.Html", 'w') ;
fwrite($fh, $output) ;
fclose($fh) ;
2、http的post實現

//extract data from the post
extract($_POST) ;
//set POST variables
$url = 'http://www.jzxue.com/get-post.PHP' ;
$fIElds = array(
                        'lname'=>urlencode($last_name) ,
                        'fname'=>urlencode($first_name) ,
                        'title'=>urlencode($title) ,
                        'company'=>urlencode($institution) ,
                        'age'=>urlencode($age) ,
                        'email'=>urlencode($email) ,
                        'phone'=>urlencode($phone)
                );
//url-ify the data for the POST
foreach($fields as $key=>$value) { $fIElds_string .= $key.'='.$value.'&' ; }
rtrim($fIElds_string ,'&') ;
//open connection
$ch = curl_init() ;
//set the url, number of POST vars, POST data
curl_setopt($ch, CURLOPT_URL,$url) ;
curl_setopt($ch, CURLOPT_POST,count($fIElds)) ;
curl_setopt($ch, CURLOPT_POSTFIELDS,$fIElds_string) ;
//execute post
$result = curl_exec($ch) ;
//close connection
curl_close($ch) ;
