How to Install the Chilkat PHP Extension on Windows

1. Download

The download contains the following files:

	license.txt
	README.txt
	phpinfo.php
	showExtDir.php
	test.php
	chilkat.php
	chilkat.dll

2. Unzip to any Directory

Use a tool such as 7-Zip or zip functionality built into Windows Explorer to unzip.

3. Copy Files to the PHP extensions directory.

Copy both chilkat.php and chilkat.dll to the PHP extensions directory

To find the path of the PHP extensions directory, run the showExtDir.php script:

php showExtDir.php

4. Edit php.ini to Automatically Load the Chilkat Extension

Locate the php.ini configuration file for your PHP installation. Open it in a text editor, find the "Dynamic Extensions" section, and add the following line:

extension=chilkat.dll

5. Run test.php to Verify

Run the test.php script to verify that the Chilkat extension is properly installed:

php test.php

The test.php script encrypts and decrypts a string. If successful, the output will look like this:
