What is this "iif" in php means?

Question

Has anyone see this "iif" in php before? What is that actually? I try to search the documentation for it in php.net but I cant found any. Anyone can give a simple example of how to use this "iif"?

Answer 1

The function iif does not exist in the standard PHP libraries. But in most cases it is a 'short if expression' such as: (condition ? true : false).

function iff($tst,$cmp,$bad) {
    return(($tst == $cmp)?$cmp:$bad);
}

echo iff('one','two','three');
echo iff('four','four','ok');
