如何判断实例的方法已经过时?
最近写代码遇到过一个这样的错误:
PHP Deprecated: Function MongoDB::authenticate() is deprecated
说authenticate这个方法已经过时,请问我执行这方法之前如何判断一下?
谢谢!
回复讨论(解决方案)
Deprecated 已过时
但只是说:在不远的将来,这个方法会废除。但现在还是能用的
如果你不愿换用替代方法,那么可屏蔽掉该错误

我是想用if(函数是否过时)这样的方法作判断,不知道有没有判断函数是否过时这样的函数。
这个跟版本有关系,显示Deprecated的,最好使用官方提供的新方法。因为以后的版本有可能会废弃以前的写法。
可以用版本来判断。
例如:
if(PHP_VERSION > xxx){
....
}else{
....
}
