curl_setopt_array

(PHP 5 >= 5.1.3, PHP 7, PHP 8)

curl_setopt_array — 为 cURL 传输会话批量设置选项

说明

curl_setopt_array(CurlHandle $handle, array $options): bool

为 cURL 传输会话批量设置选项。这个函数对于需要设置大量的 cURL 选项是非常有用的，不需要重复地调用 curl_setopt()。

参数

handle: 由 curl_init() 返回的 cURL 句柄。
options: 一个 array 用来确定将被设置的选项及其值。数组的键值必须是有效的 curl_setopt() 常量或者是它们对等的整数值。

返回值

如果全部的选项都被成功设置，返回 true。如果选项不能被成功设置，马上返回 false，忽略其后的任何在 options 数组中的选项。

更新日志

版本	说明
8.0.0	`handle` 现在接受 CurlHandle 实例；之前接受 resource。

示例

示例 #1 初始化新的 cURL 会话并抓取 web 页面

<?php
// 创建新 cURL 资源
$ch = curl_init();

// 设置 URL 和相应的选项
$options = array(CURLOPT_URL => 'http://www.example.com/',
                 CURLOPT_HEADER => false
                );

curl_setopt_array($ch, $options);

// 抓取 URL 并把它传递给浏览器
curl_exec($ch);

// 关闭 cURL 资源，并且释放系统资源
curl_close($ch);
?>

注释

注意:
就 curl_setopt() 来说，传递数组到 CURLOPT_POST 将会把数据以 multipart/form-data 的方式编码，然而传递 URL-encoded 字符串将会以 application/x-www-form-urlencoded 的方式对数据进行编码。

If you are writing a mini API for your library, and if you are doing merging of options, remember to use the union operator (+) !

So something like this will definitely fail. This is because array_merge effectively resets all the keys in the array into running numbers:

<?php
function post($url, $options = array) {
    $ch = curl_init();
    curl_setopt_array($ch, array_merge(array(
        CURLOPT_HEADER => 1,
        CURLOPT_RETURNTRANSFER => 1,
        .....
     )));
?>

Rather, this is the correct way of doing it:

<?php
function post($url, $options = array) {
    $ch = curl_init();
    curl_setopt_array($ch, array(
        CURLOPT_HEADER => 1,
        CURLOPT_RETURNTRANSFER => 1,
        .....
     ) + (array) $options);
?>

In case that you need to read SSL page content from https with curl, this function can help you:



<?php



function get_web_page( $url,$curl_data )

{

    $options = array(

        CURLOPT_RETURNTRANSFER => true,         // return web page

        CURLOPT_HEADER         => false,        // don't return headers

        CURLOPT_FOLLOWLOCATION => true,         // follow redirects

        CURLOPT_ENCODING       => "",           // handle all encodings

        CURLOPT_USERAGENT      => "spider",     // who am i

        CURLOPT_AUTOREFERER    => true,         // set referer on redirect

        CURLOPT_CONNECTTIMEOUT => 120,          // timeout on connect

        CURLOPT_TIMEOUT        => 120,          // timeout on response

        CURLOPT_MAXREDIRS      => 10,           // stop after 10 redirects

        CURLOPT_POST            => 1,            // i am sending post data

           CURLOPT_POSTFIELDS     => $curl_data,    // this are my post vars

        CURLOPT_SSL_VERIFYHOST => 0,            // don't verify ssl

        CURLOPT_SSL_VERIFYPEER => false,        //

        CURLOPT_VERBOSE        => 1                //

    );



    $ch      = curl_init($url);

    curl_setopt_array($ch,$options);

    $content = curl_exec($ch);

    $err     = curl_errno($ch);

    $errmsg  = curl_error($ch) ;

    $header  = curl_getinfo($ch);

    curl_close($ch);



  //  $header['errno']   = $err;

  //  $header['errmsg']  = $errmsg;

  //  $header['content'] = $content;

    return $header;

}



$curl_data = "var1=60&var2=test";

$url = "https://www.example.com";

$response = get_web_page($url,$curl_data);



print '<pre>';

print_r($response);



?>

This function does not mix with `curl_file_create` (`CURLFile` object) and `CURLOPT_POSTFIELDS`. Took me forever to figure out, but essentially I was getting an "Invalid filename" PHP warning and the files weren't being sent. I was able to correct the issue in a matter like so:

curl_setopt_array($curl, $curlOpts);
curl_setopt($curl, CURLOPT_POSTFIELDS, $postFields);

I removed the `$postFields` value from `$curlOpts` and set it separately using `curl_setopt`.

You can use CURLOPT_HEADERFUNCTION  with a callback inside an object.  This makes is it easy to capture the headers for later use.  For example:



<?php

class Test

{

    public $headers;



    //...



    public function exec($opts)

    {

        $this->headers = array();

        $opts[CURLOPT_HEADERFUNCTION] = array($this, '_setHeader');

        $ch = curl_init();

        curl_setopt_array($ch, $opts);

        return curl_exec($ch);

    }



    private function _setHeader($ch, $header)

    {

        $this->headers[] = $header;

        return strlen($header);

    }



    

}



$test = new Test();

$opts = array(

   //... your curl opts here

);

$data = $test->exec($opts);

print_r($test->headers);

?>



...something like that



(This works in php v. 5.1.4)

You might be tempted to use array_merge with arrays where CURLOPT constants are the keys, but beware.

<?php
array_merge([], [CURLOPT_FOO => "foo"], [CURLOPT_BAR => "bar"]);
?>

Since these constants are numeric, array_merge will happily reindex:

<?php
[0 => "foo", 1 => "bar"];
?>

Important note: the option CURLINFO_HEADER_OUT is *ignored* by curl_setopt_array(). You *must* use curl_setopt() to set this option.

(True in PHP v7.3.27 at least)

Once upon a time I've got an error like "Problem with the SSL CA cert (path? access rights?)". Since what I was doing was pretty much an administrative task with no actual security issues involved, I decided to disallow certificate validation and this is where the most interesting stuff began.

First I did it like this and it worked:

        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);

Next I thought, "But hey, I don't want any hardcoded stuff here. Let's use it in a configurable way!". And so I did something like this:

// in configuration
$CURL_OPTIONS = array(CURLOPT_SSL_VERIFYPEER => 0, CURLOPT_SSL_VERIFYHOST => 0);

...........

// in place of two direct calls from earlier
            curl_setopt_array($ch, $CURL_OPTIONS);

And I was so happy, there was no error anymore... and do you think I was happy for a long time? If so, then you're wrong. It stopped giving an error, while it didn't start to work!

I checked the actual data but they were allright. Then I thought: "Is it the curl_setopt_array() problem? Let's make it a cycle." The way it is mentioned in this help, actually.

            foreach ($CURL_OPTIONS as $name => $value)
            {
                curl_setopt($ch, $name, $value);
            }

And... it did not work the same way as with the curl_setopt_array() call. And the data were still allright...

So, if by chance you can't set CURL options with the curl_setopt_array() call, then now you know what to do and you know it is definitely not you who is to blame.

P.S.
By the way, the configuration used was:
Linux i-ween.com 3.2.0-4-amd64 #1 SMP Debian 3.2.73-2+deb7u3 x86_64
PHP Version 5.5.17

Starting in PHP 5.2.0, CURLOPT_FOLLOWLOCATION can't be set via curl_setopt_array() (or curl_setopt()) when either safe_mode is enabled or open_basedir is set.  In these cases, the order of CURLOPT_* settings in the array can be important.
