数组拆分有关问题

数组拆分问题
假设数组a：

array (<br />
  0 => <br />
  array (<br />
    'po_num' => 'DYNP-770266110-00',<br />
    'plant' => 'DYNP',<br />
    'get_date' => '2013-09-09',<br />
    'cust_no' => '12647212',<br />
    'total' => '60',<br />
    'snp' => '15',<br />
    'mount' => '4',<br />
    'lp_no' => 'P000000D',<br />
  ),<br />
  1 => <br />
  array (<br />
    'po_num' => 'DYNP-770266110-00',<br />
    'plant' => 'DYNP',<br />
    'get_date' => '2013-09-09',<br />
    'cust_no' => '12654172',<br />
    'total' => '615',<br />
    'snp' => '15',<br />
    'mount' => '41',<br />
    'lp_no' => 'P000000D',<br />
  ),<br />
)

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？

    'cust_no' => '12647212',<br />
    'total' => '60',<br />
    'snp' => '15',<br />
    'mount' => '4',<br />
    'lp_no' => 'P000000D',<br />
  ),<br />
  1 => <br />
  array (<br />
    'po_num' => 'DYNP-770266110-00',<br />

    'snp' => '15',<br />
    'mount' => '11',<br />
    'lp_no' => 'P000000D',<br />
  ),<br />
)<br />

    'total' => '225',<br />
    'snp' => '15',<br />
    'mount' => '15',<br />
    'lp_no' => 'P000000D',<br />
  ),<br />

    'snp' => '15',<br />
