My Collection of PHP Performance Benchmarks
This appears to be a benchmarking tool rather than an article to summarize. It's a collection of PHP performance microbenchmarks comparing different methods for common string and array operations (checking if strings are empty, comparing strings, searching within strings, etc.), with execution times measured in milliseconds. The author emphasizes that these are microbenchmarks with limited real-world applicability, and provides practical conclusions like preferring `===` over `==` for comparisons, using `strlen()` to detect the string '0', and choosing `strpos()` for substring searches.
