How can file permissions impact the ability to access and execute files in PHP, particularly on Windows 7/8?

File permissions can impact the ability to access and execute files in PHP on Windows 7/8 by restricting the user's ability to read, write, or execute certain files. To solve this issue, you can adjust the file permissions to allow the PHP script to access and execute the necessary files.

// Set file permissions to allow access and execution
chmod("path/to/file.php", 0755);
