I just helped one of our developers with a weird problem. The piece of code he was working on contained roughly this:
if ($str!='')
{
echo "Hello $str";
}
He was importing a CSV file that didn't contain a value for $str, so $str was an empty string. So it should skip the echo statement according to the above code, right?
Wrong. The script echoed "Hello ". It completely did the $str!='' wrong.
