gotcha with PHP typecasting
<?php
$amount = 17.50;
print (int) $amount * 100; # => 1700 # My implementation. I was wrong.
print (int) ($amount * 100); # => 1750 # After bugfix. PHP first casts, then multiplies.

Isset acts weird in PHP.
<?php
function foo($bar = NULL) {
if (isset($bar)) {
print "bar is set\n";
var_dump($bar);
}
else {
print "bar is not set\n";
var_dump($bar);//If not set should throw at least a NOTICE.

another WTF in PHP. Makes sense, technically, but as a use it makes no sense.
<?php
function foo($bar) {
var_dump($bar);
}
foo(array()); # => array(0) {}
## Works as expected. But now...
function foo(&$bar) {
var_dump($bar);
