我如何在第n个字段之后拆分字符串并从PHP中的其余部分创建一个数组？(How could I split a string after the n

我如何在第n个字段之后拆分字符串并从PHP中的其余部分创建一个数组？(How could I split a string after the n-th field and create an array from the remaining parts in PHP?)

我有以下字符串：

*/3 * * * * echo yes

我想要做的是创建一个包含2个元素的数组，其中元素在第5个字段之后彼此分开：

$result = [ "*/3 * * * *", "echo yes" ];

在Linux bash shell中我会使用：

echo "*/3 * * * * logger yes" | cut -d' ' -f1-5 echo "*/3 * * * * logger yes" | cut -d' ' -f6-

你可以看到它是一个cron-entry。 因此，编写RegEx会非常不方便，因为字段可能会发生变化。 好吧，我可以编写一个RegEx，它用空白分隔符将元素彼此分开，但我想知道PHP中是否有任何类似于GNU cut或awk函数，我可以使用它来分割这两个部分在第5场之后。

我怎么能用PHP实现相同的结果？

I have the following string:

*/3 * * * * echo yes

What I want to do is to create an array with 2 elements from that, where the elements are separated after the 5th field from each other:

$result = [ "*/3 * * * *", "echo yes" ];

In Linux bash shell I would have just used:

echo "*/3 * * * * logger yes" | cut -d' ' -f1-5 echo "*/3 * * * * logger yes" | cut -d' ' -f6-

As you can see it's an cron-entry. So writing a RegEx would be rather inconvenient as the fields can change. Ok, I could write a RegEx which splits the elements from each other with a whitespace delimiter, but I'm wondering is there any function in PHP which is similar too GNU cut or awk, which I could use for that which splits the two parts after the 5th field.

How could I achieve the same result with PHP?

尝试这个 ：

$result = [ implode('', array_slice(explode(' ', $string), 0, 5), implode('', array_slice(explode(' ', $string), 5) ];

Try this :

$result = [ implode('', array_slice(explode(' ', $string), 0, 5), implode('', array_slice(explode(' ', $string), 5) ];
