数组函数 array functions 有98个
字符串函数 string functions 有77个
这样就有98+77=175个了
还有文件操作系统 filesystem functions
php options/info functions
....
好多啊，我该如何学习呢，困惑，望各位大侠指点一二
回复内容：最常用的php函数是google()和http://php.net()这些函数根本没有重要不重要之分，
用到了就会觉得它重要，用不到自然就无所谓，
其实函数什么的就是基本功，哪怕记不住，也必须知道有这么个函数，用的时候必须能查到。
常见的函数根本就不需要去记，多用几次自然就记住了。
除了这些函数外，还有一些经典的常用代码片段也是需要记住的。你可以联系我,或者留下你的邮箱,我这个还是相对比较多而且是常用的
