print needs strings so this is a conversion from boolean into string. These
are the rules:

http://es2.php.net/manual/en/languag...string.casting

"A boolean TRUE value is converted to the string "1". Boolean FALSE is
converted to "" (the empty string). This allows conversion back and forth
between boolean and string values."

You may find var_dump() useful.

print's overrated, good ol echo, tried and true and also fast than
print (if ever speed did count)

The only little difference is in semantics, not in speed. In practice it
won't matter anyway.

If casted to a string, a FALSE will become the empty string, which makes
perfect sense and is described in the manual.

I'm going off language construct versus function but yeah, I've never
ran into where I've noticed a difference.

JFTR: Both are language constructs. Indeed 'print' behaves more like a
function, though (it sets a return value), but still doesn't require
parentheses.

hmm, I'll have to go inform someone of this, was told print = function
