[ale] [OT] need help with 2 simple lines of php

[Brian]

How about having the function return a boolean and do
this instead:
 if (function($sendemail($param)) {
     echo "Sendemail";
 }

Otherwise, you can set $sendmail as a global variable
and have your function return a the new $sendmail
value. You can also pass $sendmail using the pass by
reference operator "&". This way, the function will
affect the variable $sendmail upon return.
