Try this:
<?php
$i=0;
foreach($model->authors as $key=>$author) {
if(++$i<count($model->authors)) {
echo '<a href="http://192.168.171.46:9090/search/index?keyword='.$author->name.'">'.$author->name.';</a>';
} else {
echo '<a href="http://192.168.171.46:9090/search/index?keyword='.$author->name.'">'.$author->name.' </a>';
}
}
Or if you don’t mind a slight change use this because it is a little simpler:
<?php
$ret="";
foreach($model->authors as $key=>$author)
$ret.=($ret?'; ':'').'<a href="http://192.168.171.46:9090/search/index?keyword='.$author->name.'">'.$author->name.'</a>';
echo $ret;
