<? $i = 0;

<a href="http://192.168.171.46:9090/search/index?keyword=<? echo $author->name ?>"><? echo $author->name.' ' ?></a>;

<? }

但它显示了这个行语法错误，意
试试这个：
<?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>';
}
}
或者，如果您不介意稍作更改，请使用它，因为它更简单一些：
<?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;
假设你正在编写PHP，这样做是这样的：
<?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>";
}
}
?>
<?php
$i = 0;
foreach( $model->authors as $key => $author){
if(++$i<count($model->authors)){
?>
<a href="http://192.168.171.46:9090/search/index?keyword=<?php echo $author->name; ?>"><?php echo $author->name.' '; ?></a>;
<?php
}
else{
?>
<a href="http://192.168.171.46:9090/search/index?keyword=<?php echo $author->name; ?>"><?php echo $author->name.' '; ?></a>
<?php
}
}
?>
我看到您对语法感到非常困惑 - 也许您应该考虑至少在开始时使用带有语法检查的编辑器？
<?
$i = 0;
foreach ($model->authors as $key => $author):
if (++$i < count($model->authors)): ?>
<a href="http://192.168.171.46:9090/search/index?keyword=<?= $author->name ?>"><?= $author->name ?>;</a>
<? else: ?>
<a href="http://192.168.171.46:9090/search/index?keyword=<?= $author->name ?>"><?= $author->name ?> </a>
<? endif;
endforeach;
?>
或更短的版本。
<?
$i = 0;
foreach ($model->authors as $key => $author): ?>
<a href="http://192.168.171.46:9090/search/index?keyword=<?= $author->name ?>"><?= $author->name,++$i < count($model->authors) ? ';' : ' ' ?></a>
<?
endforeach;
?>
