curl_setopt_array

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

curl_setopt_arrayCURL 転送用の複数のオプションを設定する

説明

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

cURL セッション用の複数のオプションを設定します。 この関数が便利なのは大量の cURL オプションを設定する場合で、 何度も繰り返して curl_setopt() をコールせずにすみます。

パラメータ

handle

curl_init() が返す cURL ハンドル。

options

設定するオプションとその値を指定した配列。キーとして使用できるのは、 有効な curl_setopt() 定数か、 その定数に対応する整数値だけです。

戻り値

すべてのオプションがうまく設定できた場合に true を返します。 うまく設定できないオプションがあった時点で即時に false が返され、options 配列に含まれるそれ以降のオプションは無視されます。

変更履歴

バージョン 説明
8.0.0 handleCurlHandle クラスのインスタンスを期待するようになりました。 これより前のバージョンでは、resource を期待していました。

例1 新規に CURL セッションを初期化、ウェブページを取得する

<?php
// 新しい cURL リソースを作成します
$ch = curl_init();

// URL その他のオプションを適切に設定します
$options = array(CURLOPT_URL => 'http://www.example.com/',
CURLOPT_HEADER => false
);

curl_setopt_array($ch, $options);

// URL の内容を取得し、ブラウザに渡します
curl_exec($ch);

// cURL リソースを閉じ、システムリソースを開放します
curl_close($ch);
?>

注意

注意:

curl_setopt() と同様、配列を CURLOPT_POST に渡すとデータを multipart/form-data でエンコードします。 一方 URL エンコードされた文字列を渡すと、データを application/x-www-form-urlencoded でエンコードします。

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.
