假设数组a：
array ( 0 => array ( 'po_num' => 'DYNP-770266110-00', 'plant' => 'DYNP', 'get_date' => '2013-09-09', 'cust_no' => '12647212', 'total' => '60', 'snp' => '15', 'mount' => '4', 'lp_no' => 'P000000D', ), 1 => array ( 'po_num' => 'DYNP-770266110-00', 'plant' => 'DYNP', 'get_date' => '2013-09-09', 'cust_no' => '12654172', 'total' => '615', 'snp' => '15', 'mount' => '41', 'lp_no' => 'P000000D', ),)
当满足整个total为一定条件时，将数组拆分开来。例中total为675，假设拆分条件为total满足225，也就是拆分为3个数组，如何能将数组拆分成这样？
//barray ( 0 => array ( 'po_num' => 'DYNP-770266110-00', 'plant' => 'DYNP', 'get_date' => '2013-09-09', 'cust_no' => '12647212', 'total' => '60', 'snp' => '15', 'mount' => '4', 'lp_no' => 'P000000D', ), 1 => array ( 'po_num' => 'DYNP-770266110-00', 'plant' => 'DYNP', 'get_date' => '2013-09-09', 'cust_no' => '12654172', 'total' => '165', 'snp' => '15', 'mount' => '11', 'lp_no' => 'P000000D', ),)//carray ( 0 => array ( 'po_num' => 'DYNP-770266110-00', 'plant' => 'DYNP', 'get_date' => '2013-09-09', 'cust_no' => '12647212', 'total' => '225', 'snp' => '15', 'mount' => '15', 'lp_no' => 'P000000D', ),）//darray ( 0 => array ( 'po_num' => 'DYNP-770266110-00', 'plant' => 'DYNP', 'get_date' => '2013-09-09', 'cust_no' => '12647212', 'total' => '225', 'snp' => '15', 'mount' => '15', 'lp_no' => 'P000000D', ),）

...
能不能变成这样？把3组区分出来。

如果mount项的值也发生改变，是不是和这个一样？
$t = 225;foreach($a as $v) { $t1 = $v['total']; $v['total'] = $t1 % $t; $res[] = $v; $t1 -= $v['total']; while($t1 >= $t) { $v['total'] = $t; $t1 -= $t; $res[] = $v; }}print_r($res); 能不能获取这样的结果？

当然可以，不过有什么意义呢？

当然可以，不过有什么意义呢？
我是想记循环输出的结果，foreach($res1 as $value)这样。
当然可以，不过有什么意义呢？
我用了array_chunk，怎么结果变成了这样？
Array( [0] => Array ( [0] => Array ( [0] => Array ( [po_num] => DYNP-770266110-00 [plant] => DYNP [get_date] => 2013-09-09 [cust_no] => 12647212 [total] => 60 [snp] => 15 [mount] => 4 [lp_no] => P000000D ) [1] => Array ( [po_num] => DYNP-770266110-00 [plant] => DYNP [get_date] => 2013-09-09 [cust_no] => 12654172 [total] => 165 [snp] => 15 [mount] => 11 [lp_no] => P000000D ) ) ) [1] => Array ( [0] => Array ( [po_num] => DYNP-770266110-00 [plant] => DYNP [get_date] => 2013-09-09 [cust_no] => 12654172 [total] => 225 [snp] => 15 [mount] => 15 [lp_no] => P000000D ) ) [2] => Array ( [0] => Array ( [po_num] => DYNP-770266110-00 [plant] => DYNP [get_date] => 2013-09-09 [cust_no] => 12654172 [total] => 225 [snp] => 15 [mount] => 15 [lp_no] => P000000D ) ))
