Using hash functions in php

[webber]

Hello,

How can I use hash functions in php?

This page
http://us3.php.net/manual/en/function.hash-algos.php

Shows the following code:
=======
<?php
print_r(hash_algos());
?>
=======

and says:

=======
The above example will output:

Array
(
[0] => md4
[1] => md5
[2] => sha1
...
=======


When I try the code on my site, I get the following error message:
Fatal error: Call to undefined function hash_algos() in /home/... on line 2

What am I doing wrong?

Thanks,
Webber

Unless php verson is 5.1.2 or better you need the hash extenson module.

why not

$password="thisisit";
$passhash=md5("$password");
echo "$passhash";

You have your choice of
md5()
md5_file()
sha1()
sha1_file()

you might also want to look at mcrypt or crc32 as I have no idea what you are trying to accomplish
