本文实例讲述了php实现递归与无限分类的方法，分享给大家供大家参考。具体实现方法如下：
<?phpecho "<pre>";$area = array(array("id"=>1,"area"=>"北京","pid"=>0),array("id"=>2,"area"=>"广西","pid"=>0),array("id"=>3,"area"=>"广东","pid"=>0),array("id"=>4,"area"=>"福建","pid"=>0),array("id"=>11,"area"=>"朝阳区","pid"=>1),array("id"=>12,"area"=>"海淀区","pid"=>1),array("id"=>21,"area"=>"南宁市","pid"=>2),array("id"=>45,"area"=>"福州市","pid"=>4),array("id"=>113,"area"=>"亚运村","pid"=>11),array("id"=>115,"area"=>"奥运村","pid"=>11),array("id"=>234,"area"=>"武鸣县","pid"=>21)); function t($arr,$pid=0,$lev=0){ static $list = array(); foreach($arr as $v){ if($v["pid"]==$pid){ echo str_repeat(" ",$lev).$v["area"]."<br />"; //这里输出，是为了看效果 $list[] = $v; t($arr,$v["id"],$lev+1); } } return $list;}$list = t($area);echo "<hr >";print_r($list);?>希望本文所述对大家的php程序设计有所帮助。
