The setAccessible() methods of various Reflection objects have been deprecated, as those no longer have an effect.

Calling ReflectionClass::getConstant() for constants that do not exist has been deprecated.

Calling ReflectionProperty::getDefaultValue() for properties without default values has been deprecated.

SPL

Unregistering all autoloaders by passing the spl_autoload_call() function as a callback argument to spl_autoload_unregister() has been deprecated. Instead if this is needed, one should iterate over the return value of spl_autoload_functions() and call spl_autoload_unregister() on each value.

Passing null to readdir(), rewinddir(), and closedir() to use the last opened directory has been deprecated. Provide the last opened directory explicitly instead.

Passing integers outside the interval [0, 255] to chr() is now deprecated. This is because a byte can only hold a value within this interval.
