Understanding PHP Type Coercion

Question

I saw this small piece of code that is evading my understanding:

Answer 1

It is not really an answer, but if you try:

$a = '0e4620974319065090195629887368549';
$b = '0e8304004519934940580242199033918';
echo floatval($a) . '
' . floatval($b);var_dump($a == $b);

You get:

0

0

bool(true)

Now, if you try:

$a = '0e4620974319065090195629887368549';
$b = '1e8304004519934940580242199033918';
echo floatval($a) . '
' . floatval($b);var_dump($a == $b);

You get:

0

INF

bool(false)

My guess is that PHP converts the strings to floats and gives comparison result using the floats obtained, which are not correct anyway, but that is another story.
