Check existence of a PHP Function in PHP

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.

If it is helpful for you please make comments and share it.
