How can PHP scripts interact with file permissions on a server and potentially cause conflicts with file access?

PHP scripts can interact with file permissions on a server by attempting to read, write, or execute files. If the PHP script does not have the necessary permissions to access a file, it can cause conflicts with file access. To solve this issue, ensure that the PHP script has the appropriate permissions set on the server to access the files it needs. 

// Check file permissions before attempting to access the file
if (is_readable('example.txt')) {
    $file_contents = file_get_contents('example.txt');
    echo $file_contents;
} else {
    echo "Unable to read file due to insufficient permissions.";
}
