数组转换合并

本帖最后由 u012984377 于 2014-08-22 15:09:59 编辑
Array ( [0] => Array ( [id] => 9 [ti] => 我 ) [1] => Array( [id] => 10 [ti] => 们 ) [2] => Array( [id] => 11 [ti] => 中 )[3] => Array( [id] => 11 [ti] => 国 ))
这个转换成一维数组ID做为KEY,转换我会,但遇到相同的就合并怎么做?
如果得到一个一维数组,把得到的一维数组与下面的合并,如果KEY相等就替换值;

Array ( [7] => 爱[8] => 我 [9] => 11 [10] => 33333 [11] => 中 [12] => 华 )

目前练习数组遇到的两个问题,请高手指导。搞了快一天,还是失败了。。。-_-
------解决方案--------------------
$a = Array (<br />  Array( 'id' => 9,  'ti' => '我' ),<br />  Array( 'id' => 10, 'ti' => '们' ),<br />  Array( 'id' => 11, 'ti' => '中' ),<br />  Array( 'id' => 11, 'ti' => '国' )<br />);<br />$res = array();<br />foreach($a as $r) {<br />  if(isset($res[$r['id']])) $res[$r['id']] .= $r['ti'];<br />  else $res[$r['id']] = $r['ti'];<br />}<br />print_r($res);
