这是我发现的闷热：

function slug($phrase, $maxLength=100000000000000)
    {
        $result = strtolower($phrase);

        $result = preg_replace("/[^A-Za-z0-9\s-._\/]/", "", $result);
        $result = trim(preg_replace("/[\s-]+/", " ", $result));
        $result = trim(substr($result, 0, $maxLength));
        $result = preg_replace("/\s/", "-", $result);

        return $result;
    }

my problem is i want to create a vice versa for that replace dash to space

我的问题是我想创建一个反之亦然的替换短划线到空间

示例输入：

dash-to-space

DASH-到空间

example output

示例输出

dash to space

冲向太空

我怎样才能做到这一点？

4 个解决方案

#1

You can use this lookaround based preg_replace:

您可以使用此基于环视的preg_replace：

$result = preg_replace('/(?<!\s)-(?!\s)/', ' ', $input);

RegEx Demo

This will avoid replacing - by space if it is surrounded by space.

如果被空间包围，这将避免替换空间。

#2

the first lines are only cleaning up the string.

第一行只是清理字符串。

The last line performs the replace function.

最后一行执行替换功能。

switching the parameters around should do the trick

切换参数应该可以解决问题

$result = preg_replace("/\-/", " ", $result);

$ result = preg_replace（“/ \ - /”，“”，$ result）;

#3

It will help you :

它会帮助你：

$output = str_replace(',', ' ', $result);

#4

$result = str_replace('-', ' ', $result); => - to spaces

$ result = str_replace（' - '，''，$ result）; => - 到空格

$result = str_replace(' ', '-', $result); => spaces to -

$ result = str_replace（''，' - '，$ result）; =>空格到 -
