4、书写和调试简单的PHP代码
从语法上看,PHP语言近似于C语言。可以说,PHP是借鉴C语言的语法特征,由C语言改进而来的。我们可以混合编写PHP代码和HTML代码,不仅可以将PHP脚本嵌入到 HTML 文件中,我们甚至还可以把HTML 标签也嵌入在 PHP 脚本里。以下是你可以采用的几种方法。你可以选用其中一种你最适合的并且就这样坚持这种方法!
从HTML中分离
以下是可以使用的方法:
. . . ?> 
 
 

与Perl和C一样,在PHP中用“;”来分隔语句。那些从HTML中分离出来的标志也表示语句的结束。
注释
PHP支持C,C 和Unix风格的注释方式:
/* C,C 风格多行注释 */ // C 风格单行注释 # Unix风格单行注释


5、如何处理简单的PHP错误1)你要把PHP.ini 里的 display_errors   =   On 才可以显示错误位置
2)习惯使用echo  或者 print 打印
3)学会使用注释来屏蔽符号来调试
4)要懂得看错误信息
