<br />array(22) {<br />  [0]=><br />  array(6) {<br />    ["CheckID"]=><br />    string(16) "1001"<br />    ["PicMemo"]=><br />    string(3) "102"<br />  }<br />  [1]=><br />  array(6) {<br />    ["CheckID"]=><br />    string(16) "1005"<br />    ["PicMemo"]=><br />    string(3) "15"<br />  }<br />  [2]=><br />  array(6) {<br />    ["CheckID"]=><br />    string(16) "1002"<br />    ["PicMemo"]=><br />    string(3) "102"<br />  }<br />  [3]=><br />  array(6) {<br />    ["CheckID"]=><br />    string(16) "1003"<br />    ["PicMemo"]=><br />    string(3) "171"<br />  }<br />  [4]=><br />  array(6) {<br />    ["CheckID"]=><br />    string(16) "1004"<br />    ["PicMemo"]=><br />    string(3) "102"<br />  }<br />  [5]=><br />  array(6) {<br />    ["CheckID"]=><br />    string(16) "1005"<br />    ["PicMemo"]=><br />    string(3) "171"<br />  }<br />  ...<br /> }<br />

数组$arr;按照 'PicMemo'排序 将相同的值放在一起,键重组;
3q了!


------解决方案--------------------
foreach($ar as $v) $r[] = $v['PicMemo'];
array_multisort($r, $ar);
print_r($ar);
