curl_setopt_array

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

curl_setopt_array — Belirtilen cURL oturumuna çok sayıda seçenek atar

Açıklama

curl_setopt_array(CurlHandle $tanıtıcı, array $seçenekler): bool

Belirtilen cURL oturumuna çok sayıda seçenek atar. curl_setopt() işlevini defalarca kullanmak yerine çok sayıda seçeneği bir kerede atamak için yararlıdır.

Bağımsız Değişkenler

tanıtıcı: curl_init() işlevinden dönen bir cURL tanıtıcısı.
seçenekler: Atanacak seçenekleri ve değerlerini içeren dizi. Ahahtarlar geçerli curl_setopt() sabitleri veya bunların sayısal eşdeğerleri olmalıdır.

Dönen Değerler

Belirtilen seçeneklerin tümü atanabilmişe true döner. Bir seçenek başarıyla atanamazsa diğer seçenekler atanmaksızın işlev false ile döner.

Sürüm Bilgisi

Sürüm:	Açıklama
8.0.0	`tanıtıcı` için artık bir CurlHandle örneği bekleniyor; evvelce, resource türünde bir değer beklenirdi.

Örnekler

Örnek 1 - Yeni bir cURL oturumunun ilklendirilmesi ve bir HTML sayfasının alınması

<?php
// Yeni bir cURL özkaynağı oluşturalım
$ct = curl_init();

// URL'yi ve ilgili seçenekleri belirtelim
$options = array(CURLOPT_URL => 'http://www.example.com/',
                 CURLOPT_HEADER => false
                );

curl_setopt_array($ct, $options);

// URL'yi tarayıcıya aktaralım
curl_exec($ct);

// cURL özkaynağını kapatıp sistem özkaynaklarını serbest bırakalım
curl_close($ct);
?>

Notlar

Bilginize:
curl_setopt() işlevinde olduğu gibi, CURLOPT_POSTFIELDS seçeneğine bir dizinin aktarılması verinin multipart/form-data olarak kodlanmasına, bir URL kodlu dizge atanması ise verinin application/x-www-form-urlencoded olarak kodlanmasına sebep olur.

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);

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)

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 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"];
?>

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.

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

There is no CURLOPT_MAXFILESIZE in the PHP module but it's function only works with Content-Length headers anyway.  There are two ways of checking download sizes, one is after the download is complete using filesize(), the other is as the download is running allowing you to terminate before wasting time and disk space.



<?php

$GLOBALS['file_size'] = 0;

$GLOBALS['max_file_size'] = 1024 * 1024;

function on_curl_header($ch, $header)

{

    $trimmed = rtrim($header);    

    if (preg_match('/^Content-Length: (\d+)$/', $trimmed, $matches))

    {

        $file_size = $matches[1];

        if ($file_size > $GLOBALS['max_file_size']) {

            // handle error here.

        }

    }

    return strlen($header);

}



function on_curl_write($ch, $data)

{

    $bytes = strlen($data);

    $GLOBALS['file_size'] += $bytes;

    if ($GLOBALS['file_size'] > $GLOBALS['max_file_size']) {

        // handle error here.

    }

    return $bytes;

}



$ch = curl_init();

$options = array(CURLOPT_URL        => 'http://www.php.net/',

         CURLOPT_HEADER        => false,

         CURLOPT_HEADERFUNCTION    => 'on_curl_header',

         CURLOPT_WRITEFUNCTION    => 'on_curl_write');

curl_setopt_array($ch, $options);

curl_exec($ch);

// ...

?>

it should be noted that when using CURLOPT_POSTFIELDS in a loop, CURLOPT_POSTFIELDS appends to the sting. You can use unset() if you don't want this sort of behavior.



<?php

//this will append postfields



while(true) {

    $options = array(CURLOPT_POSTFIELDS => 'foo=bar&foo2=bar');

    $ch = curl_init("http://www.example.com");

    curl_setopt_array($ch, $options);

    curl_exec($ch);

    curl_close($ch);

}



//this will NOT append postfields

while(true) {

    $options = array(CURLOPT_POSTFIELDS => 'foo=bar&foo2=bar');

    $ch = curl_init("http://www.example.com");

    curl_setopt_array($ch, $options);

    curl_exec($ch);

    curl_close($ch);

    unset($options[CURLOPT_POSTFIELDS]);

}

?>
