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？
