Answer 1

假设您正在编写PHP，请执行以下操作：

<?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>"; 
    }
}
?>

Answer 2

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，如果你不介意稍微改变，请使用它，因为它更简单：

<?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;

<?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
    }
}
?>

我发现你对语法非常困惑 - 也许你应该考虑至少在开始时使用编辑器进行语法检查？

Answer 4

<?
    $i = 0;
    foreach ($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;
?>

<a href="…"> syntax error unexpect something</a>
