Now that iam thinking of it more and more, i don't have to turn the 'path' back to a 'number'

So, what i want is a function foo() that does this:

foo( "some long string" )  -->  1234

=====================
1. User requests a specific html page( .htaccess gives my script the absolute path for that .html page) 
2. turn the 'path' to 4-digit number and save it as 'pin'  (how?)
3. i store that number to the database. I DONT EVEN HAVE TO STORE THE HTML PAGE'S PATH TO THE DATABASE ANYMORE!!! this is just great! 


At some later time i want to check the weblog of that .html page


1. request the page as:  http://mydomain.gr/index.html?show=log
2. .htaccess gives my script the absolute path of the requested .html file
3. turn the 'path' to 4-digit number and save it as 'pin' (this is what i'am asking)
4. select all log records for that specific .html page  (based on the 'pin' column)


Since i have the requested 'path' which has been converted to a database stored 4-digit number, i'am aware for which page i'am requesting detailed data from, so i look upon the 'pin' column in the database and thus i know which records i want to select.

No need, to turn the number back to a path anymore, just the path to a number, to identify the specific .html page

Can this be done?
