php多维数组合并成一个数组
Array ( [0] => Array ( [id] => 1 ) [1] => Array ( [id] => 2 ) )
------解决思路----------------------
由于你没有给出你需要的格式，所以只能举一例
$a = Array(<br /> Array( 'id' => 1 ),<br /> Array( 'id' => 2 )<br />);<br /><br />$a = array_map('current', $a);<br />print_r($a); Array<br />(<br /> [0] => 1<br /> [1] => 2<br />)<br /><br />
$a = Array(<br /> Array( 'id' => 1 ),<br /> Array( 'id' => 2 )<br />);<br />$ar = array();<br />foreach($a as $v) $ar[] = $v['id'];<br />print_r($ar);
