[Ads]

How do I use Cron Jobs to Do some PHP Function, EG Reset Databse Feilds, and back up Data bse and send emails, Things like that.

[cooldude832]

you write the script

you tell your cron to do it however your system lts you

Why use a Cron, Couldn't i just use PHP to Read the Time, and use an If statement?

[cooldude832]

because php can't initialize itself

cron is like you go to mydomain.com/RunScript.php in firefox

okay, and what can i write Cron jobs in?

[cooldude832]

nothing

you tell the crontab a date and a time to execute a given file that is all

Alright, how do u make a crontab?

[Ken2k7]

What do you wanna do?

 

Assign a time

 

Time:

* * * * * => Execute every minute

0 * * * * => Execute every Hour

0 0 * * * => Execute every mid-night

0 0 0 * * => Execute every Month

0 0 0 0 * => Execute every Weekday

 

Assign path to php

 

Assign a UNIX command for a job

 

Assign the PHP pathfile

 

That's it. In that order (I think)

1.crontab -e

 

2. 30 23 * * * /home/path to your this script/yourscript.php

    (run this program each night as 11.30 PM )

3. save and exit

Well it executes a file so unless you tell the file to popup a box to the screen, it won't just automatically pop it up.

dear ads,

 

cron is driven by a crontab, a configuration file that specifies shell commands to run periodically on a given schedule.

 

Generally, the schedules modified by crontab are enacted by a daemon, crond, which runs constantly in the background and checks once a minute to see if any of the scheduled jobs need to be executed. If so, it executes them. These jobs are generally referred to as cron jobs.

 

 

CRON ARE BACKGROUND PROCESSES WHICH RUN SLIENTLY AND EXECUTE YOUR SCRIPT WITHOUT ANY POP UPS or so.

 

I think your need to read some tutorial about cron and it will help you more to understand them.
