How Do I Send Multiple Cookies with file_get_contents()?

Sending Multiple Cookies with file_get_contents()

The PHP manual demonstrates how to send cookies using stream contexts with file_get_contents(). However, the example only shows how to send a single cookie. This article explores how to send multiple cookies using this method.

Consider the following code:

<code class="php">// Create a stream
$opts = array(
  'http' => array(
    'method' => "GET",
    'header' => "Accept-language: en\r\n" .
              "Cookie: foo=bar\r\n"
  )
);

$context = stream_context_create($opts);

// Open the file using the HTTP headers set above
$file = file_get_contents('http://www.example.com/', false, $context);</code>

This code sends a single cookie named "foo" with the value "bar". To send multiple cookies, you can use the following approaches:

Option 1: Use the ; separator to combine cookie pairs into a single "Cookie" header.

<code class="php">$opts['http']['header'] .= "Cookie: user=3345; pass=abcd\r\n";</code>

Option 2: Send separate "Cookie" headers for each cookie.

<code class="php">$opts['http']['header'] .= "Cookie: user=3345\r\nCookie: pass=abcd\r\n";</code>

Option 3 (Recommended): Use the ; separator to combine multiple cookie pairs into a single "Cookie" header. However, separate each cookie pair with a space to improve readability.

<code class="php">$opts['http']['header'] .= "Cookie: user=3345; pass=abcd\n";</code>
