requires that passwords be
 
 
 
included in the script at
 
 
 
some point. This information

wrap your PHP scripts.
 
 
 
Protecting your scripts from
 
 
 
prying eyes is called
 
 
 
"wrapping." When
 
 
 
you wrap a script, it is
 
 
 
called by another script
 
 
 
that hides your script and
 
 
 
performs a number of
 
 
 
security checks to ensure
 
 
 
only authorized use is made
 
 
 
of it. This article covers
 
 
 
how to use a script wrapper.
