How can file permissions be adjusted in PHP to allow for file creation on a server?

To adjust file permissions in PHP to allow for file creation on a server, you can use the `chmod()` function to set the appropriate permissions for the file or directory. This function takes two arguments: the file path and the permissions in numeric format (e.g., 0644 for read and write permissions for owner, read permissions for group and others). Make sure to set the permissions accordingly to allow the server to create files. 

$file = 'path/to/file.txt';
$permissions = 0644;

if (file_exists($file)) {
    chmod($file, $permissions);
    echo "File permissions updated successfully.";
} else {
    echo "File does not exist.";
}
