Comparing Three PHP Methods to Multiply an Integer by 1000: String Concatenation, Direct Multiplication, and 1024‑Minus‑24 Approximation

This article examines three ways to enlarge a positive integer by a factor of one thousand in PHP—concatenating "000", multiplying by 1000, and using the expression X*1024‑X*24—benchmarks each method with ten million iterations, analyses the performance results, and discusses why the binary‑based formula may be slower than direct multiplication.
