Php preg_匹配此模式的所有内容

我有这个模式，我想用它来提取/image/字段后的数字，我尝试了这个模式，我在线检查了，它为第一个链接提供了所需的输出，但对于其他链接，它没有提供所需的输出 这是我的模式

  /\sample.com\/image\/(.*)\//

这是我的绳子

乙二醇

我只想在/image/field之后提取数字我不想要图像名称我想要的输出是

     4205476
     4453948
      427185

---

etc字符串中的所有数字都使用此正则表达式

~\/\image\/（.*？）\/~

preg_match_all('~\/\image\/(.*?)\/~', $str, $matches);
print_r($matches[1]);

试试这个：

/.*sample\.com\/image\/(\d+)\/.*/

---

您需要调整正则表达式：

$regex = '@sample\.com/image/([0-9]+)/@'

preg_match_all('@sample\.com/image/([0-9]+)/@', $str, $m);
print_r($m);

预期产出：

Array
(
    [0] => Array
        (
            [0] => sample.com/image/4205476/
            [1] => sample.com/image/4453948/
            [2] => sample.com/image/427185/
            [3] => sample.com/image/1323868/
            [4] => sample.com/image/2505314/

            [7] => sample.com/image/4322305/
            [8] => sample.com/image/4261476/
            [9] => sample.com/image/3386911/
            [10] => sample.com/image/4663949/
        )

    [1] => Array
        (
            [0] => 4205476
            [1] => 4453948
            [2] => 427185
            [3] => 1323868
            [4] => 2505314
            [5] => 3300481
            [6] => 1046646
            [7] => 4322305
            [8] => 4261476
            [9] => 3386911
            [10] => 4663949
        )

)

现在您需要记住，PHP将返回它匹配的所有内容，包括正则表达式字符串中不需要的部分

从PHP手册：

对结果进行排序，以便$matches[0]是完整模式的数组 matches，$matches[1]是由第一个匹配的字符串组成的数组 括号中的子模式，依此类推

你能告诉我这个~能做什么吗。我尝试过类似的方法，但我的方法不起作用，而且您的方法很好。

~

是正则表达式的分隔符。你甚至可以使用

@

@sachin，你没有在

.com

之前用反斜杠逃跑，这是你的问题。这也是正确的<代码>~sample\.com\/image\/（.*？\/~我已经接受了答案，就是这样。我没有做任何投票等。thx对于你的回答我不是指你，投票否决需要125个声誉，所以不是你：）
