unknown function

[zbangee]

guys i need your help again :)
i've got a problem i have a little login script that uses for crypting the password the sha1 function...
the script works ok on my machine a windows based computer... but when i try to upload it to a web hosting server ( a debian 3.0 stable server with php 4.1.3 and with the additional php4-mhash library instaled )

The problem is that when i try to execute the script it gives me an error like: "Fatal error: Call to undefined function: sha1() in ..." and gives me the line that i used the sha1 function...
Any ideea?

btw the library "libdigest-sha1-perl" is also installed...
thanks.

Just because the library is installed on the machine doesn't mean that PHP was compiled to use it, which is usually the case when you get that error.

Actually, the clue is PHP 4.1.3
sha1() dates from PHP 4.3.0
