事情是这样的，我们几个要做一个大学生二手网站，可是我们是学PHP的，老师说PHP是上个年代的东西，没人用啦，Java才是未来，因为Java的执行效率确实比php高。我没有黑PHP，也没有黑Java，各有各的长处。毕竟php是最美的语言。大家误会啦。
回复内容：
我只想知道谁告诉你的java是未来哦，原来是老师说的java是未来，我不想列举全球top网站中有多少运用到php，我只觉得作为一个老师，言辞如此不严谨。换编程语言不如换老师 在你商城规模大到一定程度前，java还是php根本不影响你怎么运作。如果是创业初期，快速上线验证商业模式然后快速迭代才是真理。 什么php还是java根本不是关键，是不是自己写的也不是关键。 《Execution in the Kingdom of Nouns》：http://steve-yegge.blogspot.com/2006/03/execution-in-kingdom-of-nouns.html

开发语言没你想的那么重要，无论java还是php都有非常多重量级的应用 你们不要嘲笑题主，javascript真的是未来。

PHP人好找，建议选PHP 学生级的网站，你怕php不能满足你的用户需求？还没毕业呢就担忧起php
的未来。。。 小商城的话无所谓用什么写，不过php的人好找，而且更便宜。
商城大了的话，总是要花很多钱做的，差别也不应该上知乎问了，你就该问真正的专家了 推荐用PHP，反正也是课程设计，后期有机会做大的话，再考虑用JAVA呗
PS：同是大学狗，第一个商城是用JAVA做的，差点没累死我~~ 你想的太多了 java是偏后端和服务器端的语言，扩展性好，强壮，但是如果是想快速搭建商业小网站级别的，建议使用php,现成框架多，速度快，以后用户量上去了，在移植java,毕竟有成本管控
