已知数组a和b。
<br /> //数组a:<br /> array (<br /> 0 => <br /> array (<br /> 'cust_no' => '310F6 1VA5A',<br /> 'lotno' => '2X15',<br /> 'part_count' => '32',<br /> ),<br /> 1 => <br /> array (<br /> 'cust_no' => '310F6 1VA5A',<br /> 'lotno' => '2Z25',<br /> 'part_count' => '32',<br /> ),<br /> )<br /> <br /> //数组b:<br /> <br /> array (<br /> 0 => <br /> array (<br /> 'cust_no' => '310F6 1VA5A',<br /> 'total' => '48',<br /> ),<br /> )<br />
<br /> //数组a:<br /> array (<br /> 0 => <br /> array (<br /> 'cust_no' => '310F6 1VA5A',<br /> 'lotno' => '2X15',<br /> 'part_count' => '32',<br /> ),<br /> 1 => <br /> array (<br /> 'cust_no' => '310F6 1VA5A',<br /> 'lotno' => '2Z25',<br /> 'part_count' => '16',<br /> ),<br /> )<br />
<br /> //数组a:<br /> array (<br /> 0 => <br /> array (<br /> 'cust_no' => '310F6 1VA5A',<br /> 'lotno' => '2X15',<br /> 'part_count' => '0',<br /> ),<br /> 1 => <br /> array (<br /> 'cust_no' => '310F6 1VA5A',<br /> 'lotno' => '2Z25',<br /> 'part_count' => '16',<br /> ),<br /> )<br />
