英文:
Get the dynamic number after the last "/" of external url
问题
我想提取外部URL的最后动态数字部分。
```https://data.aboss.com/v1/agency/1001/101010/events/xxxxxx```
```php
$url = https://data.aboss.com/v1/agency/1001/101010/events/;
$value = substr($url, strrpos($url, '/') + 1);
value="<?php echo $value; ?>"
结果应该是xxxxxx。

使用explode有多种方法来实现这一目标，最简单的一行代码如下所示：
echo explode("/events/", $url)[1];
或者，如果在'events/xxxxxx'之后可能有其他内容：
$url = "https://data.aboss.com/v1/agency/1001/101010/events/1524447/other/123456";
echo explode("/", explode("/events/", $url)[1])[0]; // 1524447
您还可以使用preg_match来使用正则表达式：
$url = "https://data.aboss.com/v1/agency/1001/101010/events/1524447/other/123456";
$matches = [];
preg_match("~/events/(\d+)~", $url, $matches); // 捕获"/events/"之后的数字
echo($matches[1]); // 1524447
英文:
There are many ways to do this, the simplest one-liner would be to use explode:
echo explode("/events/", $url)[1];
Or if something may come after 'events/xxxxxx':
$url = "https://data.aboss.com/v1/agency/1001/101010/events/1524447/other/123456";
echo explode("/", explode("/events/", $url)[1])[0]; // 1524447
You can also use a regex with preg_match:
$url = "https://data.aboss.com/v1/agency/1001/101010/events/1524447/other/123456";
$matches = [];
preg_match("~/events/(\d+)~", $url, $matches); // captures digits after "/events/"
echo($matches[1]); // 1524447

你可以使用PHP中的parse_url()和pathinfo()函数来获取URL的最后一部分。尝试以下代码，
<?php
$url = "https://data.aboss.com/v1/agency/1001/101010/events/xxxxxx";
$path = parse_url($url, PHP_URL_PATH);
$value = pathinfo($path, PATHINFO_FILENAME);
echo $value;
英文:
To get the last part from the url, you can use parse_url() and pathinfo() function in PHP. Try following code,
<?php
$url = "https://data.aboss.com/v1/agency/1001/101010/events/xxxxxx";
$path = parse_url($url, PHP_URL_PATH);
$value = pathinfo($path, PATHINFO_FILENAME);
echo $value;
