Are there any potential pitfalls to be aware of when using PHP to compress and transfer directories between servers?

When using PHP to compress and transfer directories between servers, one potential pitfall to be aware of is the size of the directory being compressed. Large directories may consume a lot of memory during compression, potentially causing memory limit errors or slowing down the server. To avoid this, you can set the memory limit in your PHP script before compressing the directory.

// Set memory limit to prevent memory issues during compression
ini_set('memory_limit', '256M');
