Most efficient way to handle large-scale array processing in PHP 8.3 without memory exhaustion? [closed]

I’m working with large datasets (100K+ rows from MySQL) in PHP 8.3 and need to optimize memory usage. I’ve experimented with generators using yield, SplFixedArray, and processing data in chunks with array_chunk, but I’m wondering if PHP 8.3’s JIT compiler or other new features offer better solutions.

Specifically, I’d like to know if there are any measurable improvements in memory efficiency when using foreach versus array_reduce for large datasets in PHP 8.3. Does the JIT compiler help reduce memory overhead for data processing tasks? Are there any new PHP 8.3 features specifically designed for handling large datasets more efficiently?

I’m particularly interested in answers supported by benchmarks, official PHP documentation, or detailed profiling results that demonstrate memory usage differences between approaches in PHP 8.3.
