我想在这个页面中添加 li 元素,这个网站是由其他人完成的 index.php 文件包括几个 php 文件,以及它们的 main.php。
这是 main.php 的代码
<div class="center"><p class="text3"><?php echo LABEL_TXT_FORNT_PAGE_TITLE;?></p>
<div class="netw"><div>
<div class="title"><?php echo LABEL_TXT_KDMATY;?></div></div>
<p><img src="img/<?php echo $dir;?>/1.jpg" border='1' alt="img" /></p>
<p class="text1"><?php echo TXT_CONTANT_FOR_KDAMATY;?> </p>
<p class="text2"></p>
</div>
<div class="suppserv"><div>
<div class="title"><?php echo LABEL_TXT_CHECK_PRINTING;?></div></div>
<p><img src="img/<?php echo $dir;?>/2.jpg" border='1' alt="img" /></p>
<p class="text1"><?php echo TXT_CONTANT_FOR_PRINT;?>
</p>
<p class="text2"></p></div>
<div class="remote"><div>
<div class="title"><?php echo LABEL_TXT_POINT_OF_SALES;?></div></div>
<p><img src="img/<?php echo $dir;?>/3.jpg" border='1' alt="img" /></p>
<p class="text1"><?php echo TXT_CONTANT_FOR_SALES;?></p>
<p class="text2"></p></div>
</div>
<div class="line"><img src="img/12.png" alt="img" /></div>
<div class="center2">
<div class="netw">
<p class="text4"><?php echo LABEL_TXT_EXPER;?></p>
<p class="text5"><?php echo TXT_CONTANT_EXPER;?></p>
<ul>
<li><?php echo UL_EXPER_EX1;?></li>
<li><?php echo UL_EXPER_EX2;?></li>
<li><?php echo UL_EXPER_EX3;?></li>
<li><?php echo UL_EXPER_EX4;?></li>
<li><?php echo UL_EXPER_EX5;?></li>
</ul>
<p class="text2"><a href="<?php echo SITE_URL; ?>/expertise.php"><?php echo
LABEL_TXT_MORE_LINKS;?><img alt="img" src="img/<?php echo $dir;?>/11.png"></a></p>
<div class="clear"></div>
</div>
<div class="remote">
<p class="text4"><?php echo LABEL_TXT_CUSTOMER;?></p>
<p class="text5"><?php echo TXT_CONTANT_CUSTOMER;?></p>
<ul>
<li><?php echo UL_CUSTOMER_EX1;?></li>
<li><?php echo UL_CUSTOMER_EX2;?></li>
<li><?php echo UL_CUSTOMER_EX3;?></li>
<li><?php echo UL_CUSTOMER_EX4;?></li>
<li><?php echo UL_CUSTOMER_EX5;?></li>
</ul>
</div>
<div class="suppserv">
<p class="text4"><?php echo LABEL_TXT_OUR_SERVICES;?></p>
<p class="text5"><?php echo TXT_CONTANT_SERVICES;?></p><br />
</div>
</div>
注意这一行:
<li><?php echo UL_CUSTOMER_EX1;?></li>
有人可以向我解释这是什么,它不是变量也不是常数,那是什么?
