数组拆分问题-php教程-PHP中文網

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);

我是想记循环输出的结果，foreach($res1 as $value)这样。

我用了array_chunk，怎么结果变成了这样？
