为什么递归不起作用? 郁闷了

递归 遍历 php
function getTree($arr)
{
//$row = $arr;
foreach($arr as $k=>$v)
{
$tree .= '<li><span><a href="content.php?catid='.$v['catid'].'" target="right">'.$v['catname']."</a></span>";
if(is_array($v['child'])){
$tree .= '<ul>';
//遍历child子数组
foreach($v['child'] as $sv){
$tree .= '<li><span><a href="content.php?catid='.$sv['catid'].'" target="right">'.$sv['catname']."</a></span>";
// getTree($v['child']);
if(is_array($sv['child'])) {
$tree .= '<ul>';
foreach($sv['child'] as $ssv){
$tree .= '<li><a href="content.php?catid='.$ssv['catid'].'" target="right">'.$ssv['catname']."</a></li>";
}
$tree .= "</ul>";
}
$tree .= "</li>";
}
// print_r($v['child']);
// getTree($v['child']);
$tree .= "</ul>";
}
$tree .= '</li>';
}
return $tree;
