這篇文章主要介紹了php遞歸方法實現無限分類實例代碼,需要的朋友可以參考下
數組： 代碼如下: $items = array( array('id' => 1, 'pid' => 0, 'name' => '一級11' ), array('id' => 11, 'pid' => 0, 'name' => 'www.jb51.net 一級12' ), array('id' => 2, 'pid' => 1, 'name' => '二級21' ), array('id' => 10, 'pid' => 11, 'name' => '二級22' ), array('id' => 3, 'pid' => 1, 'name' => '二級23' ), array('id' => 12, 'pid' => 11, 'name' => '二級24' ), array('id' => 13, 'pid' => 12, 'name' => '三級31' ), array('id' => 9, 'pid' => 1, 'name' => '二級25' ), ); 函數： 代碼如下: function formatTree($array, $pid = 0){ $arr = array(); $tem = array(); foreach ($array as $v) { if ($v['pid'] == $pid) { $tem = formatTree($array, $v['id']); //判斷是否存在子數組 $tem && $v['son'] = $tem; $arr[] = $v; } } return $arr; }
