php > class A {

php > var_dump($obj);
object(A)#1  ( 0 ) {
}


php > $a = "aa";
php > $aa = "Hello";
php > echo $$a;
Hello


php > echo("123abc" + 1);
124

php > echo("abc123" + 1);
1


php > echo("123abc" + "1");
124
php > echo("1" + "123abc");
124


とにかく + って書くと、数値あつかいなんだ。


"abc123"のtoNumberが0


php > echo "0" == false;
1


php > echo "0" . "xA" + 1;
11


php > echo date('Y-m-d', strtotime('2010-12-32'));
