我正在尝试编写一个PHP脚本，它将采用字符串值，非常长，例如：

将其拆分为多个部分并加载到MySQL数据库。如果我输出类似的字符串，将其放在<pre>和</pre>标记之间，那么我可以看到它被拆分为以下行：

但它仍然只是一个字符串。我想我可以把它变成数组，但它仍然让人困惑我该如何做以及如何使php字符串正确地将所有内容放入正确的MySQL数据库表中。
编辑：我有一些进展。使用以下代码：
$string = '<pre>'.$string.'</pre';
$string = split("\n",$string);
$func = function($value) { return preg_split("/\s{2,}/",$value ); };
print_r(array_map($func, $string));
我有这个阵列：

现在，我们猜测有一个带有“id”，“unix hostname”，“ip address”等表的MySQL数据库。如何从数组中获取“1402945178280070”，“ns1.domain.tld”，“232.99.185.193”等值部件并将它们放入相应的数据库表中？
不幸的是，我不能依赖于数组项目编号，因为它们会不断变化。我的意思是以下数组成员：
[2] => Array
(
[0] =>
[1] => Unix hostname: ns1.domain.tld
很容易变成：
[3] => Array
(
[0] =>
[1] => Unix hostname: ns1.domain.tld
下次。
答案 0 :(得分：0)
嗯，你可以尝试这样的事情：
$string = [your original long string];
$lines = explode("\n", $string); // Create initial raw array from the string at newline characters.
$hostname = array_shift($lines); // Remove the first hostname from the first index.
$data = array('hostname' => $hostname); // Start the data array with the hostname first.
foreach ($lines as $line)
{
$line = explode(': ', $line);
// You can probably simplify this a LOT, but I wanted to break out what is happening
$key = strtolower($line[0]); // Set to lower case.
$key = preg_replace('/[^a-z0-9]+/', '_', $key); // Replace anything that is not a letter or a digit with an underscore.
$key = trim($key, '_'); // Remove leading or trailing underscores.
$data[$key] = $line[1];
}
然后你至少有一个$ data数组，如下所示：

然后你可以从那里构建一个INSERT语句。但是，它需要为数组中的每个键提供一个字段。如果数据库字段与数组中的slugs（键）不完全匹配，则必须将它们映射到其他字段。
