Grab remaining text after last "/" in a php string
提问by Roeland
So, lets say I have a $somestringthats holds the value "main/physician/physician_view".
所以，假设我有一个$somestring包含“main/physician/physician_view”的值。
I want to grab just "physician_view". I want it to also work if the passed string was "main/physician_view" or "site/main/physician/physician_view".
我只想抓住“physician_view”。如果传递的字符串是“main/physician_view”或“site/main/physician/physician_view”，我希望它也能工作。
Hopefully my question makes sense. Any help would be appreciated!
希望我的问题是有道理的。任何帮助，将不胜感激！

There are many ways to do this. I would probably use:
有很多方法可以做到这一点。我可能会使用：
array_pop(explode('/', $string));

$last_part = substr(strrchr($somestring, "/"), 1);
Examples:
例子：
php > $a = "main/physician/physician_view";
php > $b = "main/physician_view";
php > $c = "site/main/physician/physician_view";
php > echo substr(strrchr($a, "/"), 1);
physician_view
php > echo substr(strrchr($b, "/"), 1);
physician_view
php > echo substr(strrchr($c, "/"), 1);
physician_view

For another one liner, you can use the explode trick and reverse the array:
对于另一个班轮，您可以使用爆炸技巧并反转数组：
current(array_reverse(explode('/',$url)));

The other solutions don't always work, or are inefficient. Here is a more useful general utility function that always works, and can be used with other search terms.
其他解决方案并不总是有效，或者效率低下。这是一个更有用的通用实用函数，它始终有效，并且可以与其他搜索词一起使用。
/**
* Get a substring starting from the last occurrence of a character/string
*
* @param string $str The subject string
* @param string $last Search the subject for this string, and start the substring after the last occurrence of it.
* @return string A substring from the last occurrence of $startAfter, to the end of the subject string. If $startAfter is not present in the subject, the subject is returned whole.
*/
function substrAfter($str, $last) {
$startPos = strrpos($str, $last);
if ($startPos !== false) {
$startPos++;
return ($startPos < strlen($str)) ? substr($str, $startPos) : '';
}
return $str;
}
// Examples
substrAfter('main/physician/physician_view', '/'); // 'physician_view'
substrAfter('main/physician/physician_view/', '/'); // '' (empty string)
substrAfter('main_physician_physician_view', '/'); // 'main_physician_physician_view'

The Easiest way inbuilt in PHP to grab the last string after last /could be by simply using the pathinfofunction.
PHP 内置的最简单的方法/是简单地使用该pathinfo函数来获取最后一个字符串。
In fact, you could check this for yourself,
事实上，你可以自己检查一下，
$urlString = 'path/to/my/xximage.png';
$info = pathinfo($urlString);
You could do:
你可以这样做：
var_dump($info);
this will give you something like:
这会给你类似的东西：
'dirname' => string 'path/to/my/'
'basename' => string 'xximage.png'
'extension' => string 'png' (length=3)
'filename' => string 'xximage'
so to extract the images out of that link you could do:
所以要从该链接中提取图像，您可以执行以下操作：
$img=$info['basename'];
$extension=$info['extension'];
///etc...
echo $img.".".$extension; //xximage.png

Simply you can use :
只需您可以使用：
$id = substr( $url, strrpos( $url, '/' )+1 );
