条件：当arr_time和c_type,snp都相同时，把条件相同的数组合并为新的二维数组，并设定日期形式yyyy-mm-dd_$i为其序号。变成例如
array (<br /> 0 => <br /> array (<br /> 'no'=> '2014-04-08_1',<br /> 'cust_no' => '237109S92B',<br /> 'hi_no' => 'MEC38-431',<br /> 'arr_time' => '30/03/2014 9:00',<br /> 'totals' => 15,<br /> 'ch_date' => '26/03/2014 0:00',<br /> 'snp' => 15,<br /> 'mount' => 1,<br /> 'c_type' => 'D22',<br /> ),<br /> 1 => <br /> array (<br /> 'no'=> '2014-04-08_1',<br /> 'cust_no' => '237109S92B',<br /> 'hi_no' => 'MEC38-431',<br /> 'arr_time' => '30/03/2014 9:00',<br /> 'totals' => 15,<br /> 'ch_date' => '26/03/2014 0:00',<br /> 'snp' => 15,<br /> 'mount' => 1,<br /> 'c_type' => 'D22',<br /> ),<br />)
请问怎么求解？
------解决方案--------------------$res = array();<br />foreach($ar as $t) {<br /> $k = join('_', array($t['arr_time'], $t['c_type'], $t['snp']));<br /> $res[$k][] = $t;<br />}<br />print_r($res);<br />得
Array<br>(<br> [30/03/2014 9:00_D22_15] => Array<br> (<br> [0] => Array<div class="clear">
</div>
