Please welcome to our new site. You might wonder what this site is about? Well, foobar is an universal variable used for whatever reason it needs to be used. It's commonly used in coding, or preferable coding examples like the PHP example below:

$foo = "Hello, ";
$bar = "World";
echo $foo . $bar;
// This simple program renders "Hello, World"

Another description that really explain our goals with this site can be found on Wikipedia where the term foobar is a common placeholder name, also referred to as meta syntactic variable, used in computer programming or computer-related documentation. In technology, the word was probably originally propagated through system manuals by Digital Equipment Corporation in 1960s and early 1970s. Another possibility is that foobar evolved from electronics, as an inverted foo signal. This is because if a digital signal is active low (so a negative or zero-voltage condition represents a "1") then a horizontal bar is commonly placed over the signal label. The Jargon File makes a case that foo possibly predates FUBAR, but let's not mix foobar with fubar (which stands for Fucked Up Beyond All Repair).
