如何将字符串放入数组中，并用新行分隔? [英] How can I put strings in an array, split by new line?

问题描述

我的数据库中有一个带换行符的字符串.我想将该字符串转换为数组，然后对于每一行，在数组中跳一个索引位置.

I have a string with line breaks in my database. I want to convert that string into an array, and for every new line, jump one index place in the array.

如果字符串是:

My text1
My text2
My text3

我想要的结果是这样:

Array
(
    [0] => My text1
    [1] => My text2
    [2] => My text3
)

推荐答案

您可以使用 explode 函数，使用"\n"作为分隔符:

You can use the explode function, using "\n" as separator:

$your_array = explode("\n", $your_string_from_db);

例如，如果您有这段代码:

For instance, if you have this piece of code:

$str = "My text1\nMy text2\nMy text3";
$arr = explode("\n", $str);
var_dump($arr);

您将获得以下输出:

array
  0 => string 'My text1' (length=8)
  1 => string 'My text2' (length=8)
  2 => string 'My text3' (length=8)

请注意，您必须使用 double-带引号的字符串，因此\n实际上被解释为换行符.
(有关更多详细信息，请参见该手册页.)

Note that you have to use a double-quoted string, so \n is actually interpreted as a line-break.
(See that manual page for more details.)
