but I have googled.... without success

what does the following mean

if ($variable == "") This means if (variable equals null then next line?
{$variable ='%';} what does this line mean?

if $variable is an empty string, than set $variable to % (the
character).

Or evaluates to empty string (i.e. false)
testcase:

<?php

$var = false;

if($var == "")
{
echo "true\n";
}

?>
