Scalable PHP
The document discusses whether PHP can scale to support large datasets, high traffic volumes, and maintainability. While PHP has some limitations, the key to scaling is architecture not language. PHP can be used for large, complex systems by pushing issues down the stack, scaling out horizontally across servers, using caching, and maintaining small, logical code blocks.
