PHP CURL Cookie Jar
In this post, you will learn about the CURL cookie jar of the PHP programming language.
As we know, cookies are pieces of content that are sent to a user's web browser. It allows us to store information on client browsers. The Cookie Jar is a simple cookie manager which automatically handles HTTP cookies. The curl can handle cookie specific tasks.
In cookiejar, we need to set a temporary file to hold the cookies, and then we can make subsequent requests that include those newly set cookies. To manage cookies with curl, we will use the CURLOPT_COOKIEJAR and CURLOPT_COOKIEFILE options in addition to the other options. The curl reads the cookies from the file and sends them along with the request.
The CURLOPT_COOKIEJAR contains the temporary filename where the cookies will be stored.
curl_setopt($ch, CURLOPT_COOKIEJAR, '/tmp/cookies.txt');
The CURLOPT_COOKIEFILE is used when CURL is writing the cookie data back to the server.
curl_setopt($ch, CURLOPT_COOKIEFILE, '/tmp/cookies.txt');
Complete Code: PHP CURL Cookie Jar
Here, first set a temporary file name to hold the cookies. You should be careful while storing the cookie jar because if another user can access this file. They can steal the stored credentials. You need to secure the access to this file. Next, login to a login page using a username and password and store it in the cookie jar. After that, the user can make a purchase and make payment to the portal.
<?php // A temporary file to hold the cookies $cookie_jar = tempnam('/tmp','cookie'); // log in $ch = curl_init('https://www.example.com/login.php?user=smith&password=sm@Th123'); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_jar)); $page = curl_exec($ch); curl_close($ch); // purchase items $ch = curl_init('http://www.example.com/purchase.php?item=bookes'); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_jar); $page = curl_exec($ch); curl_close($ch); // make payment $ch = curl_init('http://www.example.com/payment.php'); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, 'item=bookes&amount=3000'); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_jar); $page = curl_exec($ch); curl_close($ch); // remove the cookie jar unlink($cookie_jar) or die("Can't unlink $cookie_jar"); ?>
