The location from nginx conf:
location ~/photos/resize/(\d+)/(\d+) {
# Here var1=(\d+), var2=(\d+)
}
How to I get variables from location in nginx?

The regex works pretty much like in every other place that has it.
location ~/photos/resize/(\d+)/(\d+) {
# use $1 for the first \d+ and $2 for the second, and so on.
}
Looking at examples on the nginx wiki may also help, http://wiki.nginx.org/Configuration
In addition to the previous answers, you can also set the names of the regex captured groups so they would easier to be referred later;
location ~/photos/resize/(?<width>(\d+))/(?<height>(\d+)) {
# so here you can use the $width and the $height variables
}
see NGINX: check whether $remote_user equals to the first part of the location for an example of usage.

This is apparently necessary, if there's also another nested location with another regex and regex capture groups. Because inside that other location,
$1 $2 $3etc will refer to values from the nested regex, overwriting the$1 $2 ...in the outer regex. Analias /$1in the outer regex, will use the$1from the inner regex, which likely results in file-not-found. Apr 15, 2018 at 8:46 -

(?<width>\d+)instead of(?<width>(\d+)), or is there some other reason for this -- perhaps to also get$1as well as$width? May 2, 2018 at 18:05
You may try this:
location ~ ^/photos/resize/.+ {
rewrite ^/photos/resize/(\d+)/(\d+) /my_resize_script.php?w=$1&h=$2 last;
}
