Hi there. Is it possible to make a "while" with a "else"-statement in PHP6? I know that it's not the first time this subject is up, but my research shows that a lot of people miss it. Including me. Here's an example of what I mean: --------------------- <? $i = 1; while ($i <= 10) {

    echo $i++;

} else {

    echo "The while couldn't be executed!";

} ?> --------------------- Python & Perl already have this function. So why not PHP?

The 'but everyone else is doing it' argument is particularly weak when it's not actually accurate. $ man perlsyn

The following compound statements may be used to control flow: [...]

          LABEL while (EXPR) BLOCK
          LABEL while (EXPR) BLOCK continue BLOCK

$ perl -le '$i = 99; while ($i < 10) { $i++; } else { print "Oh..."; }' syntax error at -e line 1, near "} else" I can't see any point in it myself. It doesn't read naturally and it doesn't add anything that you don't get by preceding your while with a simple if statement. -robin
