How to get PHP files and their path changed after a date - php

Question

I want to get all file names (and path) of files those updated after a date (in directory and subdirectories) using PHP.
like all files updated after 20.08.2017 ,
Below code provide only files from directory, i also need path,
$dir = "opendir(".")";
clearstatcache();
$yesdate = strtotime("-1 days");
while(false != ($file = readdir($dir)))
{
if ( substr($file,-4) == ".php" )
{
if (filemtime($file) >= $yesdate)
{
echo $file;
}
}
}
Thanks

If you're using relative paths like e.g. . or paths that follow a symbolic link, you can get the real path via the function realpath :
$actualDirectory = realpath(".");
$dir = opendir($actualDirectory);
clearstatcache();
$yesdate = strtotime("-1 days");
while(false != ($file = readdir($dir)))
{
if ( substr($file,-4) == ".php" && filemtime($file) >= $yesdate)
{
echo $actualDirectory."/".$file;
}
}

If you want to scan all sub directories until the end of the tree you need to use a recursive function.
function get_updated_files($date, $directory, $result = array())
{
$directory = realpath($directory);
$directory_content = glob($directory.'/*');
foreach($directory_content as $item) {
if(is_dir($item)) {
$result = get_updated_files($date, $item, $result);
} elseif(strtotime($date) < filemtime($item) && pathinfo($item, PATHINFO_EXTENSION) == 'php') {
$result[] = $item;
}
}
return $result;
}
$result = get_updated_files('2017-08-20', '.');

With a specified date:
$dir = opendir(dirname(__FILE__));
clearstatcache();
$dday = "20.08.2017.";
$yesdate = strtotime($dday);
while(false != ($file = readdir($dir))) {
if ( substr($file,-4) == ".php" ) {
if (filemtime($file) >= $yesdate) {
echo $file;
}
}
}
Or with today - 1 day:
$dday = date("d.m.Y", time());
$yesdate = strtotime($dday) - 86400;

You must proceed like this
function get_updated_files($date, $directory,$file_extension='php',$sameday=false, $result = array())
{
if(!$sameday){
/* really worth because actually
your code will return true for your given day and this maybe
is not the goal you are trying to achieve...*/
$date = strtotime($date)+86399;
}else{
$date=strtotime($date);
}
$directory = realpath($directory);
$directory_content = glob($directory.'\\*');
foreach($directory_content as $item) {
if(is_dir($item)) {
$result=get_updated_files($date, $item,$file_extension,$sameday,$result);
} elseif($date < filemtime($item)&& pathinfo($item, PATHINFO_EXTENSION)===$file_extension) {
$result[] = $item;
}
}
return $result;
}
$result = get_updated_files('2017-08-20', '.');
