在字符串的第一个空格处分开

Question

我有一个像这样的字符串:

红黄蓝

我想得到一个像这样的数组:

数组([0] =>红色[1] =>黄色蓝色)

如何在字符串的第一个空格中拆分？我的代码不起作用

<?php
$str = "red yellow blue";
$preg = preg_split("/^\s+/", $str);
print_r($preg);
?>

请帮我.

Answer 1

Use explode with a limit:

$array = explode(' ', $string, 2);

Just a side note: the 3rd argument of preg_split is the same as the one for explode, so you could write your code like this as well:

$array = preg_split('#\s+#', $string, 2);

References:

PHP: explode

PHP: preg_split

Answer 2

<?php
$string = "red yellow blue";
$result = explode(" ", $string, 2);
print_r($result);
?>

只是爆炸它
