This is not at all from us, but from my colleague Andrew, who showed them to me last Friday in Perl.
I am not sure if I would use either of those in production code, it's... slightly cheeky. Nevertheless, enjoy:
<?php //turn anything into a boolean $boolean_flag = !! $any_variable; //does the same as $boolean_flag = (bool) $any_variable;
I like the importance the double exclamation marks trigger when you read this in code. IT'S LIKE WHEN PEOPLE WRITE MUNDANE STUFF IN CAPS!!
<?php
//I'm clearly iterating towards 0
$counter = 100;
while($counter-->0) {
//do stuff
}
//does the same as
$counter = 100;
while($counter > 0) {
$counter--;
//do stuff
}
This one's great, too. The arrow seems to make the loop a very dynamic element. Great, have I really just explained my joke post? Shocking, I must get out more. If you've been inside for too long, let me know what unusual syntax you've come across.
