Comparison using <> operators should be documented. Between two objects, at least in PHP5.3, the comparison operation stops and returns at the first unequal property found. <?php $o1= newstdClass(); $o1->prop1='c'; $o1->prop2=25; $o1->prop3=201; $o1->prop4=1000; $o2= newstd...
If you plan to derive your own class from ArrayObject, and wish to maintain complete ArrayObject functionality (such as being able to cast to an array), it is necessary to use ArrayObject's own private property "storage". Since that is impossible to do directly, you must use ArrayObject...

Functions that return the same values given the same input always, resembling this mathematical property, are known as referentially transparent (RT). A RT function can always be directly substituted or replaced for its computed value into any expression without altering its meaning. In other words...
