The option CURLOPT_POST set to TRUE informs the session that it is a POST request to the server.The option CURLOPT_FOLLOWLOCATION set to TRUE follows any header location that is redirected by Location: header().is the target URL where we send the request with cURL.You must create an empty cookie.txt file to store the cookie in the project directory. For the CURLOPT_COOKIEJAR option, write the cookie filename cookie.txt. Supply the payload $data for the CURLOPT_POSTFIELDS option. Set the CURLOPT_FOLLOWLOCATION, CURLOPT_POST and CURLOPT_RETURNTRANSFER to TRUE. Assign the function curl_init() with the URL to ch.Īfter that, use the curl_setopt() function to set the various options for the cURL session. Next, create a variable ch to store the cURL session. Installation of the php-curl Library in Ubuntuīefore performing the authentication, we must verify whether php-curl is installed in our system. The value parameter has the value for the option.Ĭurl_exec() - It executes the predefined cURL session. The option parameter can have a wide value of options. Here, handle is the value returned by curl_init(). Let’s look at the basic php-curl functions.Ĭurl_init() - It initializes a cURL session.Ĭurl_setopt(handle, option, value) - It sets option for the cURL session. We can perform various tasks like setting cookies, using proxies, passing data over SSL connections and even authentication using php-curl. We can use this library to communicate with servers by sending HTTP requests in PHP. The cURL library is available in PHP, called php-curl. It uses the URL syntax and supports protocols like FTP, FTPS, DICT, HTTP, HTTPS, etc. CURL (Client URL) is a command-line utility that sends or receives data and files.
