不当的化解办法

这几天写php程序,感觉很多地方不如asp,asp.Net,jsp顺手,比如session使用先得session_start();,文件跳转header用的也不方便....

也许是不熟悉的php的一些特性吧,不过写多了,也就慢慢适应将就了.....

看看程序 330行,代码最后一行,这有什么错误?google搜,找到了:

In PHP 5, the following error may appears as an error entry in Apache error log or simply displays on PHP web page, even if calling to php scripts with php_info() works perfectly and successfully returns information on PHP configurations:

The error may caused by a missing curly bracket in PHP script coding. Beside, it may also caused by error in PHP coding in class definition, as in PHP, a class definition cannot be broke up and distributed into multiple files, or into multiple PHP blocks, unless the break is within a method declaration.

欺我英文不好啊?看看其它几条搜索,都没说到点子上,那就看看英文了,虽不能如数翻译,大致意思是瞧明白了:

错误发生是使用了短标签,可以在php.ini中设置short_open_tag = On

原来Parse error 提示一般是 语法错误,使用了开放的标签,语句没有结束 也就是编程基本的一些错, 比如没注意 语句结束加 ";" 或者 if(){...} 后面忘了"}" ;<?php...?>忘了"?>"。仔细检查代码,果然是一处漏掉了"}",修改程序正常运行

解决 办法

你把标题、内容,用户那三个改成<?php echo $row['title'];?>这样的就行了啊。函数就<?php echo htmtocode($row[content]); ?>

这不是主要的,至多只是显示不出数据
