PHP versions prior to 4.2.1 modified the passed array itself and
55
-
converted strings to numbers (which most of the time converted them
56
-
to zero, depending on their value).
56
+
Now emits <constant>E_WARNING</constant> when <parameter>array</parameter> values
57
+
cannot be converted to &integer; or &float;.
58
+
Previously &array;s and &object;s where ignored whilst every other value was cast to &integer;.
59
+
Moreover, objects that define a numeric cast (e.g. <classname>GMP</classname>) are now cast instead of ignored.
