PHP: touch - Manual

touch

(PHP 3, PHP 4 )

touch -- Sets access and modification time of file

Description

int touch ( string filename [, int time [, int atime]])

Attempts to set the access and modification time of the file named by filename to the value given by time. If the option time is not given, uses the present time. This is equivalent to what utime (sometimes referred to as utimes) does. If the third option atime is present, the access time of the given filename is set to the value of atime. Note that the access time is always modified, regardless of the number of parameters.

If the file does not exist, it is created.

Returnerar TRUE vid framg�ng eller FALSE vid fel.
Exempel 1. touch() example
if (touch ($FileName)) { print "$FileName modification time has been changed to todays date and time"; } else { print "Sorry Could Not change modification time of $FileName"; }

`$filename = "test.dat"; if (!file_exists($filename)) { touch($filename); // Create blank file chmod($filename,0666); }`

Neat little script that will give you a list of all modified files in a
certain folder after a certain date:

$filelist =
Array();
$filelist =
list_dir("d:\\my_folder");
for($i=0;$i<count($filelist);$i++){
	$test
= Array();
	$test =
explode("/",date("m/d/Y",filemtime($filelist[$i])));
//example
of files that are later then
//06/17/2002
	if(($test[2] > 2001)
&& ($test[1] > 16) && ($test[0] > 5)){
		echo
$filelist[$i]."\r\n";
	}
	clearstatcache();
}
function
list_dir($dn){
	if($dn[strlen($dn)-1] != '\\') $dn.='\\';
	static
$ra = array();
	$handle = opendir($dn);
	while($fn =
readdir($handle)){
		if($fn == '.' || $fn == '..')
continue;
		if(is_dir($dn.$fn)) list_dir($dn.$fn.'\\');
		else $ra[]
= $dn.$fn;
	}
	closedir($handle);
	return $ra;
}
