It changes data type based on the type of the data you assign to
the variable. In other words...

$var = 12.34; // float
$var = "12.34"; // string

Unless the data you receive from PayPal is serialized, PHP has
absolutely no idea what the data type of a specific value is; it's all
text (i.e. a string).

Still, I don't understand why you were having a problem with this.
I tested this out:

<?php

$var1 = 12.34;
$var2 = "12.34";

if( $var1 != $var2 ) {
echo "$var1 != $var2";
} else {
echo "$var1 == $var2";
}

?>

...and it echoed out "12.34 == 12.34".
