当PHP的功能名称始于强调时,就意味着什么?
例如:-building()
我知道这一建筑意味着什么,但我看到了其他职能始于强调或双重强调的地方,我不敢肯定其重要性。
在购买力平价中,职能始于两个强调,通常具有特别的意义。 手册:
PHP reserves all function names starting with __ as magical. It is recommended that you do not use function names with __ in PHP unless you want some documented magic functionality.
例如,......(a)项是一种特殊方法,在物体初始时自动被称作。
还有一个通用的“编码风格”,使用一种初步的强调来表明方法或特性是私人/受保护的。 我认为,它非常普遍。
正如其他答复所指出的,双重强调被用于“魔力”方法。 想法是,用户永远不会有意使用两种方法名称,因此几乎没有发生碰撞的风险。 我认为,光靠一点一点一点强调,那就是,在私人关键词沿用联络处的私隐性之前,单一强调是在坏(老)的老日里采用私人方法的受欢迎的公约。
在编码协调器中,如果你在控制器中开始使用强调的某种方法,则路由人知道不允许从月球上进入。
