I've been programming in PHP for years now, but I've never learned how to use any shorthand. I come across it from time to time in code and have a hard time reading it, so I'd like to learn the different shorthand that exists for the language so that I can read it and start saving time/lines by using it, but I can't seem to find a comprehensive overview of all of the shorthand.
A Google search pretty much exclusively shows the shorthand for if/else statements, but I know there must be more than just that.
By shorthand, I am talking about stuff like:
($var) ? true : false;

Here are some of the shorthand operators used in PHP.
//If $y > 10, $x will say 'foo', else it'll say 'bar'
$x = ($y > 10) ? 'foo' : 'bar';
//Short way of saying <? print $foo;?>, useful in HTML templates
<?=$foo?>
//Shorthand way of doing the for loop, useful in html templates
for ($x=1; $x < 100; $x++):
//Do something
end for;
//Shorthand way of the foreach loop
foreach ($array as $key=>$value):
//Do something;
endforeach;
//Another way of If/else:
if ($x > 10):
doX();
doY();
doZ();
else:
doA();
doB();
endif;
//You can also do an if statement without any brackets or colons if you only need to
//execute one statement after your if:
if ($x = 100)
doX();
$x = 1000;
// PHP 5.4 introduced an array shorthand
$a = [1, 2, 3, 4];
$b = ['one' => 1, 'two' => 2, 'three' => 3, 'four' => 4];
