How use cURL library when running PHP through Command Line

Posted by admin in PHP on September 17th, 2009

If you run any PHP code which using cURL extension through command line like this:

c:\>php somefile.php

it might give error that “curl_init()” function is not defined. The reason is the cURL extension “php_curl.dll” is not loaded. So, to resolve this issue you can load cURL (or any extension) dynamically in your PHP code. The “dl()” basically load PHP extension at runtime.

<?php
dl("php_curl.dll");
...
?>

How upload file using cURL?

Posted by admin in PHP on March 5th, 2009

Here I am giving an example of how you can upload file using cURL in PHP.

Code:

<?php
	$request_url = ‘http://www.akchauhan.com/test.php’;
        $post_params['name'] = urlencode(’Test User’);
        $post_params['file'] = ‘@’.'demo/testfile.txt’;
        $post_params['submit'] = urlencode(’submit’);
 
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $request_url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $post_params);
        $result = curl_exec($ch);
        curl_close($ch);
?>

Here we have first initialized the new CURL session using “curl_init” function. Then we have set few curl options for CURL session.

CURLOPT_URL: URL to fetch.

CURLOPT_POST: TRUE to regular HTML POST.

CURLOPT_RETURNTRANSFER: TRUE to return the transfer as a string of the return value of “curl_exec” instead of outputting it out directly.

CURLOPT_POSTFIELDS: The full data to post in a HTTP “POST” operation.

You can also set more options as per your requirement but these are the minimum require options for file upload. You can find more information about these options in PHP manual.

Then execute the CURL session through “curl_exec” function. This function will return the output of request.

Here the tricky part is ‘@’ symbol before file name. CURL automatically upload the give file to server or requested URL when it find the ‘@’ symbol in starting of file name.

Note: If you try this code on localhost under windows operating system then you might get the error message “CURL is failed to created the post data”. But this code is work fine under Linux environment. So, try this on your server.

The requested file “test.php” consider this request as simple POST FROM request. Like if you use this form for request.

<form method=”post” action=”test.php” enctype=”multipart/form-data”>
	<input type=”text” name=”name” value=”Test User” />
	<input type=”file” name=”file” />
	<input type=”submit” name=”submit” value=”submit” />
</form>
