curl_setopt_array

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

curl_setopt_array — Define múltiplas opções para uma transferência cURL

Descrição

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

Define múltiplas opções para uma sessão cURL. Esta função é útil para definir um alto número de opções cURL sem chamar repetitivamente a função curl_setopt().

Parâmetros

handle: Um manipulador cURL retornado por curl_init().
options: Um array especificando que opções serão definidas e seus valores. As chaves devem ser constantes válidas da função curl_setopt() ou suas equivalentes em número inteiro.

Valor Retornado

Retorna true se todas as opções forem definidas com sucesso. Se uma opção não puder ser definida com sucesso, false é retornado imediatamente, ignorando quaisquer opções posteriores do array options.

Registro de Alterações

Versão	Descrição
8.0.0	O parâmetro `handle` agora espera uma instância de CurlHandle; anteriormente, um resource era esperado.

Exemplos

Exemplo #1 Inicializando uma nova sessão cURL e recebendo uma página da web

<?php
// cria um novo recurso cURL
$ch = curl_init();

// define URL e outras opções apropriadas
$options = array(CURLOPT_URL => 'http://www.example.com/',
                 CURLOPT_HEADER => false
                );

curl_setopt_array($ch, $options);

// captura a URL e passa ao navegador
curl_exec($ch);

// fecha o recurso cURL, liberando recursos do sistema
curl_close($ch);
?>

Notas

Nota:
Assim como a função curl_setopt(), passar um array em CURLOPT_POST irá codificar os dados como multipart/form-data, enquanto que passar uma string codificada como URL irá codificar os dados como application/x-www-form-urlencoded.

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]);

}

?>
