check the file execution

[spookie]

What i want is to make sure a certain php file gets executed ONLY once in a day with the loading of a certain web page.(an alternative to cron)
so in that page i need to check if that php file has been executed in last 24hrs and if not execute the file.
how can i achieve this?

I never set a goal because u never know whats going to happen tommorow.

create a text file that would store the timestamp of the last execution of you php script and before executing the script check that timestamp - if < 24 hours then exit else update the timestamp and execute script

you can serialize a variable wich contains the timestamps too (it's nearly the same but you always work with the same variable :c\
