curl_getinfo

(PHP 4 >= 4.0.4, PHP 5, PHP 7, PHP 8)

curl_getinfo获取一个cURL连接资源句柄的信息

说明

curl_getinfo(CurlHandle $handle, ?int $option = null): mixed

获取最后一次传输的相关信息。

option

这个参数可能是以下常量之一:

选项 说明
CURLINFO_CAINFO 默认内置 CA 证书路径

CURLINFO_HTTP_CODE 最后的响应代码。自 cURL 7.10.8 起,这是 CURLINFO_RESPONSE_CODE 的旧别名
CURLINFO_FILETIME 启用了 CURLOPT_FILETIME 后检索文档的远程时间;如果返回 -1,则文档的时间未知

示例

示例 #1 curl_getinfo() 示例

<?php
// 创建 cURL 句柄
$ch = curl_init('http://www.example.com/');

// 执行
curl_exec($ch);

// 检查是否有错误发生
if (!curl_errno($ch)) {
$info = curl_getinfo($ch);
echo
'Took ', $info['total_time'], ' seconds to send a request to ', $info['url'], "\n";
}

// 关闭句柄
curl_close($ch);
?>

示例 #2 使用 option 参数的 curl_getinfo() 示例

<?php
// 创建 cURL 句柄
$ch = curl_init('http://www.example.com/');

// 执行
curl_exec($ch);

// 检测 HTTP 状态码
if (!curl_errno($ch)) {
switch (
$http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE)) {
case
200: # OK
break;
default:
echo
'Unexpected HTTP code: ', $http_code, "\n";
}
}

// 关闭句柄
curl_close($ch);
?>

注释

注意:

如果重新使用句柄,则保留此函数收集的信息。这意味着除非此函数在内部覆盖统计信息,否则将返回以前的信息。

CURLINFO_HTTP_CODE does not return a string, as the docs say, but rather an integer.

<?php
$c
= curl_init('http://www.example.com/');
if(
curl_getinfo($c, CURLINFO_HTTP_CODE) === '200') echo "CURLINFO_HTTP_CODE returns a string.";
if(
curl_getinfo($c, CURLINFO_HTTP_CODE) === 200) echo "CURLINFO_HTTP_CODE returns an integer.";
curl_close($c);
?>

returns

"CURLINFO_HTTP_CODE returns an integer."

Note, header_size include "\r\n\r\n". So if you use CURLOPT_FOLLOWLOCATION>0, CURLOPT_HEADER=true, CURLOPT_RETURNTRANSFER=true right way splite header/body:

$response = curl_exec($ch);
$curl_info = curl_getinfo($ch);
curl_close($ch);
$header_size = $curl_info['header_size'];
$header = substr($response, 0, $header_size);
$body = substr($response, $header_size);

Here you have a function that I use to get the content of a URL using cURL. This uses curl_getinfo to know if it is a regular URL or maybe a redirection.

I hope it would be useful for you:

function getUrlContent($url){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322)');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
curl_setopt($ch, CURLOPT_TIMEOUT, 5);
$data = curl_exec($ch);
$httpcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
return ($httpcode>=200 && $httpcode<300) ? $data : false;
}

Just a quick note: if you want to use curl_getinfo() with option CURLINFO_HEADER_OUT in order to debug your cURL request, you must add curl_setopt($handle, CURLINFO_HEADER_OUT, true); first while specifying the options.

curl_getinfo($ch) will also return 'redirect_url' if there is one (even if CURLOPT_FOLLOWLOCATION set to false).
I don't know why it's not in the doc..

There is a constant missing from that list. CURLINFO_REDIRECT_COUNT will give you the number of redirects it went through if CURLOPT_FOLLOWLOCATION was set.

A note about $curl_info['header_size'] (in response to the example above).

Note that the total includes the size of any received headers suppressed by CURLOPT_SUPPRESS_CONNECT_HEADERS (see: https://curl.se/libcurl/c/CURLINFO_HEADER_SIZE.html) so if you are using a proxy which adds additional headers along with this option, $curl_info['header_size'] will give you the wrong string index based on the headers available in PHP. i.e., it will eat in to the start of the response instead of being the index of the beginning of the response.

If you use curl option CURLOPT_NOBODY = true to test if distant url is available, any sites can send you an http code 400 like Cdiscount Wsdl :

$ch = @curl_init($wsdl);

if($ch === false)
return false;

@curl_setopt($ch, CURLOPT_HEADER ,true); // we want headers
@curl_setopt($ch, CURLOPT_NOBODY ,true); // dont need body
@curl_setopt($ch, CURLOPT_RETURNTRANSFER ,true); // catch output (do NOT print!)

@curl_exec($ch);

if(@curl_errno($ch)){ // should be 0
@curl_close($ch);
return false;
}

$code = @curl_getinfo($ch, CURLINFO_HTTP_CODE);

Modifying CURLOPT_NOBODY to false, http code sent is 200 otherwise http code is 400 !!!

The main doc neglects to mention that when the CURLINFO_HEADER_OUT option is set the array returned by this function will included a new property, request_header, that is a string of the headers sent in the request.

If you call curl_reset() on a handle that has already been passed to curl_exec(), and then perform a curl_getinfo() on the same handle, you may expect that you get the same result as if you called curl_getinfo() immediately after curl_init(). This is not the case, however. cURL will return the data from the previous execution. If you want to completely reset you actually need to unset the cURL handle and recreate a new one.

Keep in mind that for CURLOPT_RETURNTRANSFER it has to be set with curl_setopt() before execution:

This doesn't work:
<?php
$ch
= curl_init();
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_exec($ch);
var_dump(curl_getinfo($ch,CURLINFO_HEADER_OUT));
?>

This works:
<?php
$ch
= curl_init();
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLINFO_HEADER_OUT, true);
curl_exec($ch);
var_dump(curl_getinfo($ch,CURLINFO_HEADER_OUT));
?>
