You'll need to specify a different file for each execution of the script, otherwise you'll have issues with the file being overwritten, etc. as you suggest.

You might want to have a look at the <a href="http://www.php.net/manual/en/function.tempnam.php" rel="nofollow noreferrer">tempnam</a> (example below) as a means of generating the unique file, or simply use <a href="http://www.php.net/manual/en/function.uniqid.php" rel="nofollow noreferrer">uniqid</a>, etc. and create the file yourself.

<pre><code>&lt;?php
 session_start();
 $cookieFilePath = $_SESSION['cookiefilepath']
 ? $_SESSION['cookiefilepath']
 : tempnam(sys_get_temp_dir(), session_id().'_cookie_');
 $_SESSION['cookiefilepath'] = $cookieFilePath;
 ...
 curl_setopt($curlSession, CURLOPT_COOKIEFILE, $cookieFilePath);
 ...
?&gt;
</code></pre>

That said, you'll need to ensure that you remove these files once they're no longer required. (If this isn't within the lifetime of your script, you might want to periodically execute a tidy-up script via cron that uses <a href="http://www.php.net/manual/en/function.filemtime.php" rel="nofollow noreferrer">filemtime</a> or similar.)

Incidentally, you can simply provide a full path to the file you want to use - it doesn't have to be in the same directory that the script is in, despite what is said in the existing <a href="https://stackoverflow.com/questions/4105529/can-someone-explain-curl-cookie-handling-php">Can someone explain CURL cookie handling (PHP)?</a> question.

Multiple requests will overwrite the same file (but will probably also slow all other requests execution down due to file locking).

You could incorporate the <a href="http://php.net/manual/en/function.session-id.php" rel="nofollow"><code>session_id()</code></a> into the cookie file name so you'll have one cookie file for every client session. I'd also recommend storing the files in something like <a href="http://php.net/manual/en/function.sys-get-temp-dir.php" rel="nofollow"><code>sys_get_temp_dir()</code></a>.

something like:

<pre><code>$cookieFile = sys_get_temp_dir().PATH_SEPARATOR.session_id().'-cookies.txt';
</code></pre>

Should work fine for that.

<code>CURLOPT_COOKIEJAR</code> and <code>CURLOPT_COOKIEFILE</code> are just utilities for handling cookies in a file, like a web browser.
And it's not recommended for your case.

But you can play directly with http headers to set and retrieve cookies.

For setting you cookies

<pre><code>&lt;?php
curl_setopt($ch, CURLOPT_COOKIE, 'user=xxxxxxxx-xxxxxxxx');
?&gt;
</code></pre>

For retrieving cookies, just identify the headers that startswith <code>Set-Cookie:</code>

You can check this document for understanding how cookie headers works <a href="http://curl.haxx.se/rfc/cookie_spec.html" rel="nofollow">http://curl.haxx.se/rfc/cookie_spec.html</a> 

Usage example, quick and dirty, but definitely not standard. 

With this headers 

<pre><code>&lt;?php
$header_blob = '
Set-Cookie: PART_NUMBER=ROCKET_LAUNCHER_0001; path=/
Set-Cookie: PART_NUMBER=RIDING_ROCKET_0023; path=/ammo
';
</code></pre>

Extract cookie headers

<pre><code>$cookies = array();
if (preg_match_all('/Set-Cookie:\s*(?P&lt;cookies&gt;.+?);/i', $header_blob, $matches)) {
 foreach ($matches['cookies'] as $cookie) {
 $cookies[] = $cookie;
 }
 $cookies = array_unique($cookies);
}
var_dump($cookies);
</code></pre>

Resend cookies

<pre><code>$cookie_blob = implode('; ', $cookies);
var_dump($cookie_blob);
</code></pre>

I'm using <code>CURLOPT_COOKIEJAR</code> to store cookies to a file and <code>CURLOPT_COOKIEFILE</code> to retrieve them from the file.

What I'm wonder is what happens when multiple users are accessing the script at the same time - won't it mess up the contents of the cookie file? Also, how do I manage the cookie files so that it's possible to have multiple users at the same time?

我使用CURLOPT_COOKIEJAR将cookies存储到文件中，使用CURLOPT_COOKIEFILE从文件中检索它们。我想知道的是，当多个用户同时访问脚本时会发生什么-它不会弄乱cookie文件的内容吗？另外，如何管理cookie文件，以便可以同时拥有多个用户？
