PHP implementation recursive and Infinite classification method, PHP implementation of recursive classification

In this paper, we describe the recursive and infinite classification method of PHP, and share it for your reference. The implementation method is as follows:

<?phpecho "
"; $area = array (' ID ' =>1, ' area ' = ' Beijing ', ' pid ' =>0), array (' ID ' =>2, ' area ' = ' Guangxi ', ' pid ' =>0), Array (' ID ' =>3, ' area ' = ' Guangdong ', ' pid ' =>0), array (' ID ' =>4, ' area ' = ' Fujian ', ' pid ' =>0), array (' ID ' =>11, ' Area ' = ' Chaoyang ', ' pid ' =>1 ', array (' ID ' =>12, ' area ' = ' Haidian ', ' pid ' =>1), array (' ID ' =>21, ' area ' = ') Nanning ', ' pid ' =>2), array (' ID ' =>45, ' area ' + ' Fuzhou ', ' pid ' =>4), array (' ID ' =>113, ' area ' = ' Asian Games Village ', ' pid ' = >11), array (' ID ' =>115, ' area ' = ' Olympic Village ', ' pid ' =>11), array (' ID ' =>234, ' area ' = ' wuming county ', ' pid ' =>21 '); function T ($arr, $pid =0, $lev =0) {Static $list = Array (), foreach ($arr as $v) {if ($v [' pid ']== $pid) {  echo str_repeat (" c1/> ", $lev). $v [' area ']."
";  The output here is to see the effect  $list [] = $v;  T ($arr, $v [' id '], $lev + 1); }  } return $list;} $list = t ($area); echo "
 
   ";p Rint_r ($list);? >
