PHP Judge file modification time and date function code

PHP Tutorial determines file modification time with date function
This script when the page was last revised and output as 20 minutes ago, or XX days before the date ... Or even if you don't update too much-20 weeks before the show!

//file Name
$last _modified = Filemtime ("file.php");
 
{
$timediff = time ()-$last _modified;
 
if ($timediff < 3600)
{
if ($timediff <)
{
$returndate = "1 minute ago.";
}
Else
{
$returndate = intval ($timediff/60). "Minutes ago."
}
}
Else if ($timediff < 7200)
{
$returndate = "1 hour ago.";
}
Else if ($timediff < 86400)
{
$returndate = intval ($timediff/3600). "Hours ago."
}
Else if ($timediff < 172800)
{
$returndate = "1 day ago."
}
Else if ($timediff < 604800)
{
$returndate = intval ($timediff/86400). "Days ago."
}
 
Else if ($timediff < 1209600)
{
$returndate = "1 week ago.";
}
Else if ($timediff < 3024000)
{
$returndate = intval ($timediff/604900). "Weeks ago."
}
Else
{
$returndate = @date (' n-j-y ', $timestaMP);
if ($type = = "Fulldate")
{
$returndate = @date (' n-j-y, h:i ', $timestamp);
 
}
 
Else if ($type = = "Time")
{
 
$returndate = @date (' h:i ', $timestamp);
 
}
 
}
//display It
Print ("Last flushes:");
Print ($returndate);
 
}
?

It should be easy to understand.

$ last_modified = filemtime ("file.php"); -Change file.php to file you want to connect.
