How to access sha1() in my code?

Hi everyone,

Full disclosure: I'm an experienced programming who is relatively new to PHP. Unfortunately, I'm also in a bit of a jam. In short, my boss gave me some PHP code and said, "You have to get this working by Friday." I don't have the luxury to do the proper tutorials, otherwise I wouldn't be rushing to this forum in a bit of a panic.

Here's the problem. The code I'm working with has this line:

$variable1 = sha1("12345678".$user.$passwd);

PHP:

When I execute, the compiler gives me this result...

<br>
<b>Fatal error</b>:  Call to undefined function:  sha1() in <b>/export/qhome/dude1/script1.php</b> on line <b>38</b><br>

Code (markup):

...which I'm interpreting to mean "I don't know what this sha1() command is!" If this were C++ code (my home turf), I'd just "man sha," figure out which library I need to add, and then pop in the needed "#include ______" statement at the top of my code. That didn't work for in this case.

Does anyone have any insight?

Many, many thanks in advance!

What version of php do you have? was included in 4.3 onwards

 

Yeah, I just found out I'm on PHP Version 4.0.3pl1, which neatly explains the problem. Man, is my face red...!

Many thanks!

hash('sha1',$variable);
