Intro/mhash-Phpdoc专题

These functions are intended to work with » mhash. Mhash can be used to create checksums, message digests, message authentication codes, and more.

This is an interface to the mhash library. Mhash supports a wide variety of hash algorithms such as MD5, SHA1, GOST, and many others. For a complete list of supported hashes, refer to the constants page. The general rule is that you can access the hash algorithm from PHP with MHASH_hashname. For example, to access TIGER you use the PHP constant MHASH_TIGER.

Note:

This extension is obsoleted by Hash.

Note:

As of PHP 7.0.0 the Mhash extension has been fully integrated into the Hash extension. Therefore, it is no longer possible to detect Mhash support with <span class="function">extension_loaded; use <span class="function">function_exists instead. Furthermore, Mhash is no longer reported by <span class="function">get_loaded_extensions and related features.
