如何在多级数组中搜索文本（PHP）
我想搜索像下面这样的数组来查找pair2.php.net - 搜索域的最有效方法是什么？带有 stripos 的循环 foreach 语句？
Array
(
[0] => Array
(
[host] => php.net
[type] => MX
[pri] => 5
[target] => pair2.php.net
[class] => IN
[ttl] => 6765
)
[1] => Array
(
[host] => php.net
[type] => A
[ip] => 64.246.30.37
[class] => IN
[ttl] => 8125
)
)
这是第一条评论建议中的我的工作代码 - 不同的方式会更有效吗？
$search = 'secureserver.net';
$x='no!';
foreach($result AS $array1)
{
foreach($array1 AS $array2)
{
if(stripos($array2,$search))
{
$x='yes!';
}
}
}
echo $x;
I would like to search through an array like the one below looking for pair2.php.net - what would be the most efficient way to search through the domain? A looping foreach statement with stripos?
Array
(
[0] => Array
(
[host] => php.net
[type] => MX
[pri] => 5
[target] => pair2.php.net
[class] => IN
[ttl] => 6765
)
[1] => Array
(
[host] => php.net
[type] => A
[ip] => 64.246.30.37
[class] => IN
[ttl] => 8125
)
)
Here's my working code from the first comment's suggestion - would a different way be more efficient?
$search = 'secureserver.net';
$x='no!';
foreach($result AS $array1)
{
foreach($array1 AS $array2)
{
if(stripos($array2,$search))
{
$x='yes!';
}
}
}
echo $x;

您可以使用单个 for 循环并使用 php 中的 'in_array' 构造来查找数组中的值：-
in_array( 'pair2.php.net', $sub_array );
you could use a single for-loop and use the 'in_array' construct in php to look for the value in an array :-
in_array( 'pair2.php.net', $sub_array );
