I have written a licensing system for my script and now i saved it an file called lic.php in the root folder
I am going to encrypt that with ioncube when giving to a client side
and i will simply include

include \"lic.php\" 

to call the licensing system But the problem is when i simply include the code

include \"lic.php\" 

the user can directly remove the line to get the script worked So can some one help me in coding a script inside the lic.php which will make the script to prevent from running if the code i.e,

include \"lic.php\" 

is removed from the file Note that i will include the line

include \"lic.php\" 

in all the php files in my script
Also do you face any issues with ioncube while running??
Great Thanks!
