Changelog

The following changes have been made to functions of bundled extensions.

Version	Function	Description
Since 5.3.0	get_class	NULL became the default value for object, so passing NULL to object now has the same result as not passing any value.
Since 5.0.0	get_class	The object parameter is optional if called from the object's method.
	get_class	The class name is returned in its original notation.
	get_parent_class	The object parameter is optional if called from the object's method.
Since 4.2.0	srand	seed 成为可选，省略时会默认使用随机值。
Since 4.0.5	get_parent_class	If object is a string, returns the name of the parent class of the class with that name.
prior to 5.3.0	get_object_vars	If the object isn't an object, then get_object_vars would return FALSE
Prior to 5.1.3	imagecolorallocatealpha	Returns -1 if the allocation failed.
Prior to 4.2.0	get_class_vars	Uninitialized class variables will not be reported by get_class_vars
prior to 4.2.0	get_object_vars	If the variables declared in the class of which the object is an instance, have not been assigned a value, those will not be returned in the array
PHP 5.3.2 (PECL OCI8 1.4)	oci_set_prefetch	Before this release, rows must be >= 1.
PHP 5.3 (PECL OCI8 1.3.4)	oci_set_prefetch	Before this release, prefetching was limited to the lesser of rows rows and 1024 * rows bytes. The byte size restriction has now been removed.
