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？

<br />//b<br />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' => '165',<br />    'snp' => '15',<br />    'mount' => '11',<br />    'lp_no' => 'P000000D',<br />  ),<br />)<br />//c<br />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' => '225',<br />    'snp' => '15',<br />    'mount' => '15',<br />    'lp_no' => 'P000000D',<br />  ),<br />）<br />//d<br />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' => '225',<br />    'snp' => '15',<br />    'mount' => '15',<br />    'lp_no' => 'P000000D',<br />  ),<br />）<br />
