php 怎么读取数组中的指定值

Array ( [0] => Array ( [.id] => *1 [name] => ppp1 [service] => any [caller-id] => [password] => [profile] => default [routes] => [limit-bytes-in] => 0 [limit-bytes-out] => 0 [disabled] => false [comment] => ) [1] => Array ( [.id] => *2 [name] => ppp2 [service] => any [caller-id] => [password] => [profile] => default [routes] => [limit-bytes-in] => 0 [limit-bytes-out] => 0 [disabled] => false [comment] => ) [2] => Array ( [.id] => *3 [name] => ppp3 [service] => any [caller-id] => [password] => [profile] => default [routes] => [limit-bytes-in] => 0 [limit-bytes-out] => 0 [disabled] => false [comment] => ) )

上面这个数组，怎么能把所有name的值读取出来，整合成一个 一维数组？
新人，不太懂，大家多多指点

Answer 1

可以通过数组的键名来读取

例如：
<?php
$array = array('a'=>'a1','b'=>'b1');

echo $array['a'];
?>

或者通过数组的键值来读取键名

例如：
<?php
$array = array('a'=>'a1','b'=>'b1');

echo array_search('a',$array);
?>

Answer 2

$arr=array();
foreach($array as $value){
foreach($value as $key=>$val){

if($key=='name'){
$arr[]=$val;
}
}

}
var_dump($arr);

$array为你提供的数组。

Answer 3

<?php
foreach ($array as $key => $value) {
	foreach ($value as $k => $val) {
		if ($k == 'name') {
			$newArr[] = $val;
		}
	}
}
echo "<pre>";
print_r($newArr);
echo "</pre>";
?>

望采纳 Thx
