![]() ![]() The results above are an excerpt from PHP Hash Algorithm Benchmarks. In PHP 8.1, xxHash is the fastest hashing algorithm supported in PHP. Furthermore, none of the xxHash variants are allowed in hash_hmac function. For password hashing, use password_hash and its friends. XxHash is not a cryptographic hashing algorithm. XxHash is a streaming hash, and can be used as such: $context = hash_init('xxh3') PHP 8.1 adds support for xxHash algorithm in following variants: Some xxHash variants in fact, are faster than the RAM throughput provided CPU cache is sufficient and fits. These functions will be removed in PHP 9.0.ĭepending on the intended use case of functions, the replacements can provide a identical output, or a rather accurate output if the functions were used without expecting locale-aware formatting.įor locale-aware date/time formatting, Intl extension provides a more robust and complete solution without the undesired behavior of the setlocale function.XxHash is an extremely fast hashing algorithm that is not designed for cryptographic purposes, but provides excellent randomness and dispersion of output, and uniqueness of to minimize collisions. Using strftime / gmstrftime functions result in a deprecation notice in PHP 8.1 and later.
