方法1:
用 file_get_contents 以get方式获取内容
<?php
$url = "http://www.domain.com/?para=123" ;
$html =
file_get_contents ( $url );
echo $html ;
?>
方法2:用 file_get_contents 函数,以post方式获取url
<?php
$url =
"http://www.domain.com/test.php?id=123" ;
$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
)
);
$ctx =
stream_context_create( $opts );
$html =
@ file_get_contents ( $url , "" , $ctx );
如果需要再传递cookie数据,则把
"header" => "Content-type:
application/x-www-form-urlencoded
"
.
"Content-Length:
"
. strlen ( $data )
. "
" ,
修改为
"header" => "Content-type:
application/x-www-form-urlencoded
"
