note 84712 added to language.references

Just a side note to make developpers more careful about references. References are pretty much useful when you try to optimize your code. By the way, the time gained by referenced variables will depend of the variable type. Integer and Float variables will work quite as fast referenced or not. Whereas String and Array should be always passed by reference (you mostly divide by 10 the execution time). Objects are automatically referenced by PHP.
