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.
