PHP copy images according to time - php

Question

I want to copy images from one folder to another on server, now I use this code:
<?php
function read_dir($dir)
{
$list = array();
if (is_dir($dir))
{
if ($handle = opendir($dir))
{
while (false !== ($file = readdir($handle)))
{
if ($file != "." && $file != "..")
{
$list[] = $file;
}
}
}
closedir($handle);
}
return $list;
}
$src="oldfolder";
$dest="newfolder";
$list= read_dir($src);
foreach($list as $key => $val)
{
copy("$src/$val","$dest/$val");
}
echo "Done";
?>
But I need to copy just images selected by time - for example images uploaded between "now" and 5 min. ago..
Can anyone help?
Thanks
Now my PHP is like below. It seems that it run with "Done" result, but nothing is copied..
<?php
function read_dir($dir)
{
$list = array();
if (is_dir($dir))
{
if ($handle = opendir($dir))
{
while (false !== ($file = readdir($handle)))
{
$fpath = 'oldfolder'.$file;
if (file_exists($fpath)) {
if($file != "." && $file != ".." &&
DateTime::createFromFormat('U', filemtime($file)) < new DateTime("-5
minutes"))
{
$list[] = $file;
}
}
}
}
closedir($handle);
}
return $list;
}
$src="oldfolder";
$dest="newfolder";
$list= read_dir($src);
foreach($list as $key => $val)
{
copy("$src/$val","$dest/$val");
}
echo "Done";
?>

Answer 1

So this is my code, that works for me well - copy images between folders according to time (- 5 sec) set by other code in "time.txt" file:
<?php
function read_dir($dir)
{
$list = array();
if (is_dir($dir))
{
if ($handle = opendir($dir))
{
while (false !== ($file = readdir($handle)))
{
$fpath = 'oldfolder/'.$file;
if (file_exists($fpath)) {
$subor = fopen("./time.txt", "r");
$cas_txt=fgets($subor, 11);
fclose($subor);
$cas_zac = DateTime::createFromFormat('U', $cas_txt)->modify('-5 seconds');
if ($file != "." && $file != ".." && DateTime::createFromFormat('U',
filemtime($fpath)) > $cas_zac)
{
$list[] = $file;
}
}
}
}
closedir($handle);
}
return $list;
}
$src="oldfolder";
$dest="newfolder";
$list= read_dir($src);
foreach($list as $key => $val)
{
//copy file to new folder
copy("$src/$val","$dest/$val");
}
echo "Done";
?>
I have two more questions:
Please how can I rotate images in 180° by or after copy? Is it possible in one php code?
How can I send multiple files - images from my code - like an attachments by mail in php?
Thanks for your help.

You should use the filemtime function
