Access file in restricted folder in PHP with cURL

January 29th, 2011 by Usha Informatique Team Leave a reply »


Many times, in a software project, a developer is required to access a file in a restricted folder as an HTTP request with allow_url_open in php.ini set to OFF. This is for Windows Environment.


The viable solution here is to use cURL, a command line tool for transferring date with URL syntax.

How to make a folder restricted with .htaccess and .htpasswd?

- In Project Folder, create a folder and call it Private

- In an editor, create a new file called .htaccess with following lines of code and save it inside Private folder

AuthName “Restricted Area”
AuthType Basic
AuthUserFile D:/wamp/www/TryPhp/private/.htpasswd
require valid-user

- Go to the following URL

- EnterĀ  a username and password and it would generate a string. Copy the string

- Create a new file and paste the string generated from above step and save it as .htpasswd in Private folder

- Try to access the folder with the weburl and it would prompt for a username and password

Access the folder with cURL

- Create a file in the root of the project and put the following code in it to access the content of any file within Private folder

$curlObj = curl_init();
$username = “{chosen username}”;
$password = “{chosen encrypted password}”;
curl_setopt($curlObj, CURLOPT_URL, “http://localhost/{Project Name}/private/{PHP File}”);
curl_setopt($curlObj, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curlObj, CURLOPT_USERPWD, “$username:$password”);
$output = curl_exec($curlObj);
$transferInfo = curl_getinfo($curlObj);
print_r( $transferInfo );

Note: Replace the following variables in the above code

- {chosen username}

- {chosen encrypted password}

- {Project Name}

- {PHP File}

The line curl_setopt($curlObj, CURLOPT_RETURNTRANSFER, true); enables to retrieve the data in a variable from a remote file.

Thus in this way, you are able to successfully access a remote file using cURL.
