关于数组合并的问题
原数组:

<br />$args1 = Array(<br />		'0' => array(<br />				'0' => 'a',<br />				'1' => array(<br />					'0' => array ( 'col1' => 'A1', 'col2' => 0 )<br />				)<br />		),<br />		'1' => array(<br />				'0' => 'b',<br />				'1' => array(<br />					'0' => array ( 'col1' => 'B1', 'col2' => 1 )<br />				)<br />		)<br />);<br />$args2 = Array(<br />		'0' => array(<br />				'0' => 'a',<br />				'1' => array(<br />					'0' => Array ( 'col1' => 'A2', 'col2' => 0 ), <br />					'1' => Array ( 'col1' => 'A3', 'col2' => 0 ) <br />				)<br />		)<br />);<br />

$res = array();<br />foreach($args1 as $item) $res[$item[0]] = $item;<br />foreach($args2 as $item) $res[$item[0]][1] = array_merge($res[$item[0]][1], $item[1]);<br /><br />print_r(array_values($res));
