I would refer to the SAMATE project, which keeps a list of source and binary
analysis tools:

Using SWAAT as it comes is not entirely beneficial. The 
matches that come with it in the xml files are extremely 
naive and will false positive a LOT. For example SWAAT will 
pickup "system" as being a vulnerable call to the system 
command, even if it is within a string eg...
<?php
echo "Backup the system!" ;
?>

This is just one example, it doesn't analyse the code at all.

**********************
Finding Name
 Backup the System
 
Severity of Finding
 Medium 
 
Description
 This function appears to issues a command to the operating 
system. If user supplied input is used here it may lead to 
operating system injection attacks. Ensure all such data is validated.
 

Finding Locations
 In .\system.php, line 2 (context is <?php echo "Backup the 
System"; ?>)
**********************

Far too many false positives for this to be a useful static 
analyser. It's not analysing at all, merely grepping - badly.

I'd steer clear of it for now, it could be more useful if you 
knock up your own XML configs, but since it's functionality 
is more limited than grep, you'd be better off just knocking 
up some, grep scripts.
Even `grep system\( *` is a better match and even this is a 
naive filter.
Calling SWAAT a static analyser is a bit of an exaggeration 
of it's current capabilities.
