hash_algos()
hash_algos() — Return a list of registered hashing algorithms.
Built-in function of PHP 8.5. The manual lists it as available in PHP 5 >= 5.1.2, PHP 7, PHP 8, PECL hash >= 1.1. This page is the reference card: signature, parameters and return value, plus the changelog and the example the manual provides.
Signature
hash_algos(): array
Parameters
This function takes no parameters.
Return value
Returns a numerically indexed array containing the list of supported hashing algorithms. Note: Not all algorithms are suitable for every use case. See the Hash extension introduction for a description of the different categories (checksum, non-cryptographic, and cryptographic). Not all algorithms are suitable for every use case. See the Hash extension introduction for a description of the different categories (checksum, non-cryptographic, and cryptographic).

A runnable snippet:
print_r(hash_algos());
