数组拆分处置（整数时的处理）

数组拆分处理（整数时的处理）
已知数组a：

array (<br />  0 => <br />  array (<br />    'po_num' => '20131227-000008102',<br />    'plant' => 'JQSP',<br />    'get_date' => '2013-12-27',<br />    'cust_no' => '12654172',<br />    'total' => '225',<br />    'snp' => '15',<br />    'mount' => '15',<br />    'lp_no' => 'P000000D',<br />  ),<br />)

处理程序如下：

<br />$t = 225;<br />$k = 0;<br /><br />foreach($a as $v) {<br />$t1 = $v['total'];<br />$v['total'] = $t1 % $t;<br />$res[$k][] = $v;<br />$t1 -= $v['total'];<br />while($t1 >= $t) {<br />$v['total'] = $t;<br />$t1 -= $t;<br />$res[++$k][] = $v;<br />	}<br />	}<br />$res = array_reverse($res);<br />print_r($res);<br />

得到的结果：

Array<br />(<br />    [0] => Array<br />        (<br />            [0] => Array<br />                (<br />                    [po_num] => 20131227-000008102<br />                    [plant] => JQSP<br />                    [get_date] => 2013-12-27<br />                    [cust_no] => 12654172<br />                    [total] => 225<br />                    [snp] => 15<br />                    [mount] => 15<br />                    [lp_n<span>%本文来源gaodai#ma#com搞*代#码9网#</span><strong>搞gaodaima代码</strong>o] => P000000D<br />                )<br /><br />        )<br /><br />    [1] => Array<br />        (<br />            [0] => Array<br />                (<br />                    [po_num] => 20131227-000008102<br />                    [plant] => JQSP<br />                    [get_date] => 2013-12-27<br />                    [cust_no] => 12654172<br />                    [total] => 0 //产生了为0的项<br />                    [snp] => 15<br />                    [mount] => 15<br />                    [lp_no] => P000000D<br />                )<br /><br />        )<br /><br />)

既然是整除，那么结果应该只有一项，如何修改代码让其只有非0项生成？
