Question

PHP

there is an iframe script but there www.site.com/0063 changes to /0064 in two days how to make it change automatically in the iframe, I thought to create a task via cron but I don’t know how to make a php script

Answer 1

If php is stupid, then you write the variable to a file (number 0063) and just extract it with cron, add the desired number and overwrite

Answer 2

I thought so too, but then you need to create a database to store the number
