从 $ codes 的给定字符串我只想拥有语言数组的所有语言，所有代码到代码数组，最后所有的系列到系列数组，我怎样才能在php中执行此操作？我已经尝试过使用dom，但是其他任何方式都不可能会受到赞赏，在此先感谢。

我认为你应该看一下php的爆炸功能。
使用它你可以先用“\ n”字符分割（分隔线），然后得到第一个数组。 然后，对于每一行，您可以通过\ t进行爆炸（假设您有分隔数据的选项卡），以获得包含3个单独条目的数组，然后将所有这些数组推送到所需的数组中。
类似的东西：
$codes_array = array();
foreach($line as explode("\n",$codes) ){
$codes_array[] = explode("\t",$line);
}

$langs_ar = array();
$codes_ar = array();
$families_ar = array();
foreach(preg_split('/[\r\n]+/', $codes) as $line)
{
if (preg_match('/^(\S+\s*\S+)\s+(\S{2})\s+(\S.*\S)\s*$/', $line, $matches))
{
$langs_ar[] = $matches[1];
$codes_ar[] = $matches[2];
$families_ar[] = $matches[3];
}
}
哦，而不是3个数组，我建议一个数组存储3个字段的哈希值;或使用3个属性lang，code和family创建自己的对象。
编辑：执行相同操作的更短的方法是：
preg_match_all('/^(\S+\s*\S+)\s+(\S{2})\s+(\S.*\S)\s*$/m', $codes, $matches, PREG_SET_ORDER);
var_dump($matches);
$ matches现在是索引所有行的“对象”数组：
只是迭代它来做你想做的事。
