Delete files after x amount of time

[andre1990]

Hi guys,

 

Im a newb here, so bear with me! Still learning the ropes.

 

I want to delete all files from my server that are 6 hours old since being uploaded to the site. I believe i need a cron job? I currently have this script in its framework...

 

<?php

//time interval for deletion to occur...
$x = 30;

//timestamp
$current_time = time();

//the file you wish to delete
$file_name = 'file.txt';

//timestamp
$file_creation_time = filemtime($filename);

//extract difference
$difference = $current_time - $file_creation_time;

//if difference = $x...then delete file
if ($difference == $x) {
unlink($file_name);
}

 

Would that work automatically or would it need a cron to run it?

 

And how could i test it, that bit worries me.

 

Many thanks.

nothing works automatically if is is not said to work

 

Yes, your code may be run fron cron-task

Or you may imitate simple cron by checking time of  your customer's visits.

Not $difference == $x, but $difference >= $x

Im running on CentOS, would the Cronjob look like this?

 

#<minute> <hour> <day> <month> <dow> <command>

/* 4 * * * /link/to/command/php/file

 

Would that run every 4 hours?
