内容简介：php发送get、post请求的6种方法简明总结
方法1: 用file_get_contents 以get方式获取内容：
方法2: 用fopen打开url, 以get方式获取内容：
<?php
$fp
=
fopen
(
$url
, ‘r');
stream_get_meta_data(
$fp
);
while
(!
feof
(
$fp
)) {
$result
.=
fgets
(
$fp
, 1024);
}
echo
“url body:
$result
”;
fclose(
$fp
);
?>
方法3：用file_get_contents函数,以post方式获取url
<?php
$data
=
array
(‘foo
' => ‘bar'
);
$data
= http_build_query(
$data
);
$opts
=
array
(
‘http' =>
array
(
‘method
' => ‘POST'
,
‘header'=> “Content-type: application/x-www-form-urlencodedrn” .
“Content-Length: ” .
strlen
(
$data
) . “rn”,
‘content' =>
$data
)
);
$context
= stream_context_create(
$opts
);
$html
=
file_get_contents
(‘http:
//localhost/e/admin/test.html', false, $context);
echo
$html
;
?>
方法4：用fsockopen函数打开url，以get方式获取完整的数据，包括header和body,fsockopen需要 PHP.ini 中 allow_url_fopen 选项开启
<?php
function
get_url (
$url
,
$cookie
=false)
{
$url
=
parse_url
(
$url
);
$query
=
$url
[path].”?”.
$url
[query];
echo
“Query:”.
$query
;
$fp
=
fsockopen
(
$url
[host],
$url
[port]?
$url
[port]:80 ,
$errno
,
$errstr
, 30);
if
(!
$fp
) {
return
false;
}
else
{
$request
= “GET
$query
HTTP/1.1rn”;
$request
.= “Host:
$url
[host]rn”;
$request
.= “Connection: Closern”;
if
(
$cookie
)
$request
.=”Cookie:
$cookien
”;
$request
.=”rn”;
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
,”rnrn”);
$body
=
substr
(
$body
,4,
strlen
(
$body
));
return
$body
;
}
return
false;
}
?>
方法5：用fsockopen函数打开url，以POST方式获取完整的数据，包括header和body
<?php
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/1.1n”;
$request
.=”Host: “.
$URL_Info
[
"host"
].”n”;
$request
.=”Referer:
$referern
”;
$request
.=”Content-type: application/x-www-form-urlencodedn”;
$request
.=”Content-length: “.
strlen
(
$data_string
).”n”;
$request
.=”Connection: closen”;
$request
.=”Cookie:
$cookien
”;
$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
;
}
?>
方法6:使用curl库，使用curl库之前，可能需要查看一下php.ini是否已经打开了curl扩展
<?php
$ch
= curl_init();
$timeout
= 5;
curl_setopt (
$ch
, CURLOPT_URL, ‘http:
//www.jb51.net/');
curl_setopt (
$ch
, CURLOPT_RETURNTRANSFER, 1);
curl_setopt (
$ch
, CURLOPT_CONNECTTIMEOUT,
$timeout
);
$file_contents
= curl_exec(
$ch
);
curl_close(
$ch
);
echo
$file_contents
;
?>
