PHP lcg_value() Function – Combined Linear Congruential Generator
The article explains PHP’s lcg_value() function, which generates a pseudo‑random float between 0 and 1 by combining two linear congruential generators with periods 2^31‑85 and 2^31‑249, describes its return value, provides a PHP code example, and shows a sample output.
The PHP function lcg_value() returns a pseudo‑random floating‑point number in the range (0, 1). It combines two linear congruential generators whose periods are 2^31 − 85 and 2^31 − 249, giving a total period equal to the product of these two prime numbers.
Return value: a pseudo‑random number between 0 and 1.
