求大神帮忙解决这个数组合并问题

问题是把下面两个二维数组合并，根据他们相同的ID合并成一个数组

$arr = array(	array('id'=>1,'name'=>'zhangsan','sex'=>'n'),	array('id'=>2,'name'=>'lisi','sex'=>'v'),	array('id'=>3,'name'=>'wangwu','sex'=>'n'),	array('id'=>4,'name'=>'zhaoliu','sex'=>'v'),	array('id'=>5,'name'=>'xiaoqi','sex'=>'n'));$arr1 = array(	array('id'=>3,'age'=>'20'),	array('id'=>5,'age'=>'21'),	array('id'=>6,'age'=>'30'));

$arr = array(	array('id'=>3,'name'=>'wangwu','sex'=>'n','age'=>'20'),	array('id'=>5,'name'=>'xiaoqi','sex'=>'n','age'=>'21'));

回复讨论(解决方案)

好吧自己弄好了

$bbs = array();	foreach ($arr as $k => $v) {		foreach ($arr1 as $key => $value) {			if($value['id']==$v['id']){				$bbs[] = array_merge($arr[$k],$arr1[$key]);			}				}		}

array_merge_recursive

foreach ( $arr as $v ) {
     $tmp[$v['id']] = $v;
}
foreach ( $arr1 as $v ) {
     $tmp[$v['id']] = $v;
}

print_r($tmp);
