试试这个

 < a href =<？php echo $ pathimage。$ imagename;？> 
 class =slide
 title =
 onclick =return hs.expand（this，$ K）> 
< img src =<？php echo $ pathimage2。$ imagename;？> 
 alt =/> 
< / a> 
 

Below are the PHP variables I'd like to use in my HTML code:

var

$pathimage1="mydir/images/large/";

$pathimage2="mydir/images/thumb/";

$imagename="landscape.jpg";

$K="item1";

$row=180;

$colon=200;

how does one use these php variables in html code?

<td width=$row height= $colon >
<div class="classname">
<a href=$pathimage + $imagename 
 class="slide" 
 title="" 
 onclick="return hs.expand(this, $K)">
 <img src=$pathimage2 + $imagename  
 alt=""/>
     </a>
 </div>
 </td>

Try like this

<a href="<?php echo $pathimage.$imagename;?>" 
 class="slide" 
 title="" 
 onclick="return hs.expand(this, $K)">
 <img src="<?php echo $pathimage2.$imagename;?>"
     alt=""/>
</a>
