PHP延迟静态绑定示例分享
没怎么用过这个新特性，其实也不算新啦，试试吧，现在静态类的继承很方便了
<?php
classA{
protectedstatic$def='123456';
publicstaticfunctiontest(){
echoget_class(newstatic);
}
publicstaticfunctiontest2(){
echostatic::$def;
}
}
classBextendsA{
protectedstatic$def='456789';
}
classCextendsA{
protectedstatic$def='abcdef';
}
echoB::test();
echo'<br>';
echoC::test();
echo'<br>';
echoB::test2();
echo'<br>';
echoC::test2();
echo'<br>';
echoA::test();
echo'<br>';
echoA::test2();
echo'<br>';
//输出结果 B C 456789 abcdef A 123456
