Check existence of a PHP Function in PHP

[bbasujon]

Sometimes when you make many functions in your PHP scripts. Then you need to check the real existence of the function you need. That's why to check a function's existence, you can write a little piece of code like the following:

<?php

if(function_exists(NameOfTheFunction))

{


echo "Function Exist";


}


else


{


echo "Function doesn't exist";


}


?>


NameOfTheFunction means your function's name. If your function is LoginCheck(). Then you need to write only LoginCheck. Just omitt the () symbol.
