Extracting a number from a string ??

[jeddi]

Hi,

I have a string like this:

"villarentfethiye.example.com/18-vacationvillatrekkingturkey"

The bold element "example.com/" will stay constant and so will the "-" (dash or hyphen )
immediately after the number. The other stuff can change a lot.


I need to extract the number. In this case it is 18

What would you say is the most efficient way to extract this using php ?
I will use the number to find the record by it's id number in the db table.

Many thanks.

Try

PHP Code:

$output = preg_replace( '/[^0-9]/', '', $string );
