Question

我的数据库中列出了几种以某种写作方式出现的电话号码我想在每两个数字之后有一个空格。我以为我会这样做：

$numbers = '06-12345678';
$regex = '/(\\d{2})(\\d{1})(\\d{2})(\\d{2})(\\d{2})(\\d{2})/';
$result = preg_replace($regex, '$1 $2 $3 $4 $5 $6', $numbers);
echo $result;

但这不起作用。它只是将所有数字放在一起。

我的预期输出：

06 - 12 34 56 78

Answer 1

这应该适合你：

$numbers = "06-12345678";
echo $result = preg_replace("/(\d{2})-(\d{2})(\d{2})(\d{2})(\d{2})/", "$1 - $2 $3 $4 $5", $numbers);

正则表达式解释：

(\d{2})-(\d{2})(\d{2})(\d{2})(\d{2})

第一个捕获组（\ d {2}）
\ d {2} 匹配数字[0-9]
- 量词： {2} 正好2次
- 匹配字符 - 字面意思
第二个捕获组（\ d {2}）//＆lt; - 4x相同
\ d {2} 匹配数字[0-9]
- 量词： {2} 正好2次

输出：

06 - 12 34 56 78

带有短划线和数字的PHP preg_replace电话号码
