Read to the end at the beginning

find  ./*/public_html/stolbiki-parkovochnye -type f -name 'index.php' -exec sed -i 's/\x24GLOBALS\[\x22SLIDER_TOP\x22\] = 17258\x3B/GLOBALS["PREIM_TOP"] = 3670;/g' {} \;

./*/public_html/stolbiki-parkovochnye - from which folder the
-type f file
-name 'index.php'is - only the php index
-exec- execute with the found one
sed -i 's/было/стало/g'- zaenit in the stream and overwrite all found matches in the file
'\x24 и \x22 и \x3B I wrote this here
{} - the miracle you were looking for is the argument that you found the find it is substituted (part of exec)
\;- close the exec
result

cat index.php
GLOBALS["PREIM_TOP"] = 3670;

If you want to look at the result but not make changes, instead sed -ichange to sed -e
Since sed is dangerous for inexperienced use, it would not be sour to make a backup of these files while maintaining the directory structure.

mkdir ./tmp/backup
find./*/public_html/stolbiki-parkovochnye -type f -name 'index.php' -print0 | xargs -0 cp --parents --target-directory ./tmp/backup
