php 动态数组添加问题

$count = count($_POST['color'])

$final_result = array()

for($i=0$i<$count$i++){

//压进数组

$single_record = array(

0=>$_POST['color'][$i],

1=>$_POST['size'][$i],

2=>$_POST['number'][$i]

)

array_push($final_result, $single_record)

//插入数据库

$sql = "INSERT INTO table VALUES('".$_POST['color'][$i]."','".$_POST['size'][$i]."','".$_POST['number'][$i]."')"

mysql_query($sql)

}

$a=array(0=>array("name"=>"a","mail"=>"b"),1=>array("name"=>"d","mail"=>"e"))

 function addkey(&$val, $key, $param)

 {

 $val[$param['key']] = $param['val']

 }

array_walk($a,'addkey',array('key'=>'tel', 'val'=>'123'))

print_r($a)
