1、htmlspecialchars() 转义特别的字符为HTML实体;
'&' (ampersand) becomes '&'
'"' (double quote) becomes '"' when ENT_NOQUOTES is not set.
''' (single quote) becomes ''' only when ENT_QUOTES is set.
'<' (less than) becomes '<'
'>' (greater than) becomes '>'
2、htmlspecialchars_decode()将实体转成HTML代码,函数1的反函数
3、 htmlentities()这个是全部转换html实体,和htmlspecialchars()区别在于,这个函数是转义全部的字符,而htmlspecialchars()仅仅转义上面限定的5个特殊字符!
