What will be the output of the following PHP code?
<?php
function a()
{
function b()
{
echo 'I am b';
}
echo 'I am a';
}
b();
a();
?>
Error
Correct:
Error
Explanation: The output will be Fatal error: Call to undefined function b(). You cannot call a function which is inside a function without calling the outside function first. It should be a(); then b();
