Are there any potential licensing issues with using the Readline module in PHP?

The Readline module in PHP is licensed under the PHP License, which is compatible with most open source licenses. However, if you plan to distribute your code commercially, you may need to ensure that the PHP License is compatible with your licensing requirements. To solve potential licensing issues, you can include a copy of the PHP License in your project and make sure to comply with its terms.

// Example of including the PHP License in your project
// This code snippet should be included in a file named LICENSE.txt in your project
