提问by user723220

I've searched for hours. How can I separate a string by a "\"

我已经搜索了几个小时。如何用“\”分隔字符串

I need to separate HORSE\COW into two words and lose the backslash.

我需要将 HORSE\COW 分成两个词并去掉反斜杠。

$array = explode("\",$string);

This will give you an array, for "HORSE\COW"it will give $array[0] = "HORSE"and $array[1] = "COW". With "HORSE\COW\CHICKEN", $array[2]would be "CHICKEN"

这会给你一个数组，因为"HORSE\COW"它会给出$array[0] = "HORSE"和$array[1] = "COW"。随着"HORSE\COW\CHICKEN"，$array[2]将是"CHICKEN"

Since backslashes are the escape character, they must be escaped by another backslash.

由于反斜杠是转义字符，因此它们必须由另一个反斜杠转义。

You would use explode()and escape the escape character (\).

您将使用explode()和转义转义字符 ( \)。

$str = 'HORSE\COW';

$parts = explode('\', $str);

var_dump($parts);

Just explode()it:

就explode()这样：

$text = 'foo\bar';

print_r(explode('\', $text)); // You have to backslash your
                               // backslash. It's used for
                               // escaping things, so you
                               // have to be careful when
                               // using it in strings.

A backslash is used for escaping quotes and denoting special characters:

反斜杠用于转义引号和表示特殊字符：

• \nis a new line.
• \tis a tab character.
• \"is a quotation mark. You have to escape it, or PHP will read it as the end of a string.
• \'same goes for a single quote.
• \\is a backslash. Since it's used for escaping other things, you have to escape it. Kinda odd.

• \n是一条新线。
• \t是制表符。
• \"是一个引号。您必须对其进行转义，否则 PHP 会将其读取为字符串的结尾。
• \'单引号也是如此。
• \\是一个反斜杠。由于它用于逃避其他事物，因此您必须逃避它。有点奇怪。
