How does PHP differ from Perl in terms of file writing permissions?

In PHP, file writing permissions are typically set using the `chmod()` function, which allows you to specify the desired permissions for a file. This function takes the file path and the desired permissions as arguments, allowing you to easily control who can read, write, or execute the file. In Perl, file writing permissions are usually set using the `chmod()` function as well, but the syntax and usage may differ slightly from PHP.

// Set file writing permissions in PHP
$file = 'example.txt';
$permissions = 0644; // Read and write permissions for owner, read-only for others
chmod($file, $permissions);
