Checking File Modified Timestamp

[bschultz]

I need to check a file's timestamp (last modified) and if it's BEFORE 15 minutes past the current hour (xx:15:00) then run a shell command.

 

Here's the code

 

<?php

///////// start of time constants /////////
date_default_timezone_set('US/Central');
$fullyear = date('Y');
$year = date('y');
$month = date('m');
$day = date('d');
$now = date('Y-m-d-h');
$hour = date('g');
$hourplus1 = date('g', strtotime("Now +1 hour"));
$hourminus1 = date('g', strtotime("Now -1 hour"));
$ampm = date('A');
$rename_date = date('mdg');
$nowis = date('m');

$copy1 = "/home/rpbroadcasting/audio/S$rename_date.mp3";


if (file_exists($copy1)) {
echo system('normalize-mp3 --mp3 '.escapeshellcmd($copy1));
    $stamp1 = date ("n-j-Y g:i:s A.", filemtime($copy1));
$fifteenpastthishour = mktime(date("n"), date("j"), date("y"), date("g"), 15);
if ($stamp1 <= $fifteenpastthishour)
{
echo system(escapeshellcmd("mp3gain -g 3 $copy1"));
}
}

$copy2 = "/home/rpbroadcasting/audio/N$rename_date.mp3";
if (file_exists($copy2)) {
echo system('normalize-mp3 --mp3 '.escapeshellcmd($copy2));
    $stamp2 = date ("n-j-Y g:i:s A.", filemtime($copy2));
$fifteenpastthishour = mktime(date("n"), date("j"), date("y"), date("g"), 15);
if ($stamp2 <= $fifteenpastthishour)
{
echo system(escapeshellcmd("mp3gain -g 1 $copy2"));
}
}

$copy3 = "/home/rpbroadcasting/audio/W$rename_date.mp3";
if (file_exists($copy3)) {
echo system('normalize-mp3 --mp3 '.escapeshellcmd($copy3));
    $stamp3 = date ("n-j-Y g:i:s A.", filemtime($copy3));
$fifteenpastthishour = mktime(date("n"), date("j"), date("y"), date("g"), 15);
if ($stamp3 <= $fifteenpastthishour)
{
echo system(escapeshellcmd("mp3gain -g 1 $copy3"));
}
}

?>

 

The problem is, it's ALWAYS running the mp3gamin shell command...no matter what the timestamp of the file is.

 

Where am I going wrong with this?

 

Thanks.

stamp1 is a date string, fifteenpastthishour is an INT

Also, while it's possible the compare date strings, they have to be formatted according to some rules (which your "n-j-Y g:i:s A." does not follow). It's easier to compare numbers.

Thanks for the help!

 

After re-thinking this, I need to make sure that the mp3gain command only runs once per hour.  I think I'll have to store the count in a flat file...and compare the count.  Then, I won't have to compare the timestamp...

 

Thanks again, though!

Once an hour? The best way to do that is to make a cron job (Linux) or scheduled task (Windows). Then the script actually only runs once an hour - no messing with timestamps or dates.

[bschultz]

The script to download these mp3's runs at xx:05:xx of each hour (via cron) ...and then checks if the file exists every five minutes after that (xx:10:00, xx:15:xx, xx:20:xx...etc) to accommodate a file not being present on the remote server at xx:05:xx of the hour.

 

The normalize script (also runs via cron) also needs to run every five minutes...to accommodate a file not being present on the remote server at xx:05:xx of the hour....but I only want to normalize the mp3 file once in the hour...not every five minutes that the file exists...so was going to check the timestamp.

 

Then, I realized that method wouldn't work either...if the file downloaded after 15 minutes past the hour...it would normalize every five minutes.  So...that's why I went with a flat file and a counter on that file.

 

<?php

///////// start of time constants /////////
date_default_timezone_set('US/Central');
$fullyear = date('Y');
$year = date('y');
$month = date('m');
$day = date('d');
$now = date('Y-m-d-h');
$hour = date('g');
$hourplus1 = date('g', strtotime("Now +1 hour"));
$hourminus1 = date('g', strtotime("Now -1 hour"));
$ampm = date('A');
$rename_date = date('mdg');
$nowis = date('m');

$copy1 = "/home/rpbroadcasting/audio/S$rename_date.mp3";
if (file_exists($copy1)) {
$fp = fopen("/var/www/sportscount.txt", "r");
$count = fread($fp, 1024);
fclose($fp);
$count = $count + 1;
if ($count == 1)
{
echo system('normalize-mp3 --mp3 '.escapeshellcmd($copy1));
echo system(escapeshellcmd("mp3gain -g 3 $copy1"));
//$count = 0;
echo "Count is 1...I have to normalize\n";
}
$fp = fopen("/var/www/sportscount.txt", "w");
fwrite($fp, $count);
fclose($fp);
}





$copy2 = "/home/rpbroadcasting/audio/N$rename_date.mp3";
if (file_exists($copy2)) {
$fp = fopen("/var/www/newscount.txt", "r");
$count = fread($fp, 1024);
fclose($fp);
$count = $count + 1;
if ($count == 1)
{
echo system('normalize-mp3 --mp3 '.escapeshellcmd($copy2));
echo system(escapeshellcmd("mp3gain -g 1 $copy2"));
//$count = 0;
echo "Count is 1...I have to normalize\n";
}
$fp = fopen("/var/www/newscount.txt", "w");
fwrite($fp, $count);
fclose($fp);
}







$copy3 = "/home/rpbroadcasting/audio/W$rename_date.mp3";
if (file_exists($copy3)) {
$fp = fopen("/var/www/weathercount.txt", "r");
$count = fread($fp, 1024);
fclose($fp);
$count = $count + 1;
if ($count == 1)
{
echo system('normalize-mp3 --mp3 '.escapeshellcmd($copy3));
echo system(escapeshellcmd("mp3gain -g 1 $copy3"));
//$count = 0;
echo "Count is 1...I have to normalize\n";
}
$fp = fopen("/var/www/weathercount.txt", "w");
fwrite($fp, $count);
fclose($fp);
}

?>

 

The above is working as I want it to...then I run another (via cron) script at the the top of the hour to reset the counts to 0.

 

Thanks again everyone!
