In many code examples in PHP documention (& others also), I have seen authors referring to variables 'foo' & 'bar', but I have yet not discovered the origin of these names. I am sure there must be dozens of others who have the curiosity to find how the use of these names started. Can anyone quench the curiosities please? regards,
