예 1. traversing all hashes
mhash_get_block_size

mhash_count() returns the highest available hash id. hashes are numbered from 0 to this hash id.
?php $nr = mhash_count(); for ($i = 0; $i = $nr; $i++) {echo sprintf ("the blocksize of %s is %d\n", mhash_get_hash_name ($i), mhash_get_block_size ($i));}?

here is a list of hashes which are currently supported by mhash. if a hash is not listed here, but is listed by mhash as supported, you can safely assume that this documentation is outdated.

however, it's more than likely that these functions would prove to be useless for you when trying to implement a persistent module. typically, one would want to use the fact that the persistent resource list is really a hash table. for instance, in the mysql/msql modules, when there's a pconnect() call (persistent connect), the function builds a string out of the host/user/passwd that were passed to the function, and hashes the sql link with this string as a key. the next time someone calls a pconnect() with the same host/user/passwd, the same key would be generated, and the function would find the sql link in the persistent list.
one important thing to note: resources going into the persistent resource list must *not* be allocated with php' s memory manager, i.e., they should not be created with emalloc(), estrdup(), etc.
