php模拟get和post的几种方法(fsockopen,curl 等)
[ 2012-12-13 11:14:13 | 作者: admin ]
使用 file_get_contents
使用curl
下面这个是比较完整的方法,包含get和post

$re = file_get_contents($url);
print_r($re);
print_r($re);
使用curl
$ch = curl_init("http://www.xg98.com/") ;
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true) ;
curl_setopt($ch, CURLOPT_BINARYTRANSFER, true) ;
$output = curl_exec($ch) ;
$fh = fopen("out.html", 'w') ;
fwrite($fh, $output) ;
fclose($fh) ;
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) ;
下面这个是比较完整的方法,包含get和post
