PHP的一个IF语句总也写不好。
在此之前是读取数据库代码,此处略去。。。
然后到这里,就不会了。。
<code> if $row['name]="" or is_null($row['name']);?> <em class="bold">找人起个名字吧!</em> <?else ?> <em class="bold">这个名字还不错么</em> end if?> </code>
问题一:第一行这样写报错为:
PHP Parse error: syntax error, unexpected '$row' (T_VARIABLE), expecting '(' in I:\php\index.php on line 119
其他行有没有错暂时未知
问题二:有没有快捷的写法,即都按PHP写,而不是和HTML混写在一起,貌似这样的执行效率会很差。
好吧,我承认这是从asp改过来的,刚学PHP,也不知道去哪里查这些问题。

else漏了冒号
endif中没有空格
if最后的分号改成冒号,然后在endif后面加上分号。
if 后面的条件要用括号包起来
<code> if ($row['name']="" or is_null($row['name'])): ?> <em class="bold">找人起个名字吧!</em> else: ?> <em class="bold">这个名字还不错么</em> endif; ?> </code>
if 后面的条件要用括号括起来,$row['name],这里少了一个单引号,else要改成else:,end if 要改成 endif;
$row['name]=""
这里的name
少一个'
引号 , 还有这个判断里不应该是两个等号么?
PHP做web开发 混编是难免的。也可以用模板引擎,只不过现在你还是把混编弄理解吧。
题主,我怎么感觉你这是用的CI框架。
快捷的写法就是模板引擎了,大部分现在框架都有。比如laravel的Blade
<code>@if($row['name]="" or is_null($row['name'])) <em class="bold">找人起个名字吧!</em> @else <em class="bold">这个名字还不错么</em> @endif</code>
