- count() returns very different results and never a boolean (not even false on error condition). - therefore you should NOT use it in boolean expressions. This still *can* be done in PHP because of its lazyness. But it is discouraged if it comes to more clean code. Signed-off-by: Roland Häder <roland@mxchange.org>
