如何查找角色的最后一个实例

Question

I'm building this real estate script using PHP and I want the listing page url's to be like /listing/this-is-the-title-436. This url is generated in PHP and the last part of the url, after the last instance of ' - ' is the listing id. But I cannot find a way to find the last instance of a dash and use the rest as a variable in .htaccess.

Note that the title can have any amount of spaces therefore any amount of dashes but the listing id will always be at the end, after the last dash.

To summarize, I want urls like /listing/this-is-the-title-436 to redirect to /assets/inc/listing.php?listing=436 with .htaccess.

Any help would be appreciated, thanks!

The easiest way is to test a numerical value at the end:

RewriteEngine on
RewriteRule ^listing/.+-(\d+)$ /assets/inc/listing.php?listing=$1 [L,QSA]

But if you're not just using numeric values, you can also test for the absence of - in the last part:

RewriteRule ^listing/.+?-([^-]+)$ /assets/inc/listing.php?listing=$1 [L,QSA]
