Highway and I were talking about this earlier.

Was it

Code: Select all

if ($x) {
     include(myfile.php);
};

To include a file only if x variable was true?

Okay, yeah... I got busy so was not able to finish.

it?s:

Code: Select all

if (condition)
{
    include('my_special_file.php');
}  

of course, in phpBB3, it would be:

Code: Select all

if (condition)
{
    include("{$phpbb_root_path}my_special_file.$phpEx");
}  

As for the === expression, that is it must match both value and type.
For example...

Code: Select all

<?php
$a = 0; // var type is int
$d = false; // var type is bool (or boolean)
$c = ''; // var type is string

// an if statement tests a (condition) and if it is true, whatever is inside the { } is performed.
if ($a === false) // since $a is not exactly false, this condition evaluates to false
{
    echo '$a is exactly false';
}
else 
{
    echo '$a is not exactly false';
}
// will echo '$a is not exactly false'

// since the double equal just tests for the value, the following expression will evaluate to true...
if ($a == false)
{
    echo '$a is false';
}
// will echo '$a has the value of false'

if ($d === false) // since $d is a bool, and we are testing for bool, the expression evaluates to true
{
    echo '$d is exactly false';
}
// will echo '$d is exactly false';
?>
