The filename is passed as a parameter to the filemtime() perform. The results of the filemtime() operate is cached and a perform referred to as clearstatcache() is used to clear the cache. When working with swf files , there’s a good method to avoid the browser cache. Here is a small but helpful script that you have to use to search out which recordsdata in your server are modified after a date/time that you simply specify. This script will undergo all folders within the specified listing recursively and echo the modified recordsdata with the last modified date/time… On home windows you’ll have the ability to set the system time to any arbitrary future date, and any new files you created or edited will automatically change to that future date.
Also any kind of access on the file updates the final access time. So if you check the final access time that has been set appropriately then this updates the final access time. This is a catch 22 situation that you need to keep in mind whereas testing. The strategies we use to acquire the date/time are all static. This implies that we do not must create a File object earlier than we use these methods. You just have to move the total file path to the method and this returns a DateTime object.
When the parent theme is lively, that is nice, because get_stylesheet_directory() will level that file within the mother or father theme. ‘/dist/css/custom-style.css’), means get the file modified time of the mother or father themes dist/css/custom-style.css file. Then the error will not happen when loading a stylesheet that’s lacking that file, and you won’t must re-eneueue it from that baby theme. The fundamental technique of getting and setting the totally different dates and instances of files and directories has been demonstrated.
Some Unix filesystems could be mounted with atime updates disabled to increase the performance of such purposes; USENET news spools are a common example. In my case it was not associated to the trail or filename. If filemtime(), fileatime() or filectime() don’t work, try stat(). The code for taking a glance at a file’s date and time additionally works with directories. But when you understand you are dealing with a listing there’s a better method. The Directory class has similar strategies because the File class and they are used in the same method.
Make note that it will throw a warning because the documentation states. While tobias makes a good level for manufacturing, when error reporting is off, this could increase your efficiency over using `file_exists`. However, if error reporting is on and it is writing to a log…
The operate can turn out to be useful when dealing with browser caching. You can drive the download of a revised version of a stylesheet or page utilizing the filemtime() perform. The filemtime() PHP operate retrieves the Unix timestamp from the file. This timestamp signifies when the file was final changed. When I go to the web page supply, I see that the enqueueing labored.
To find the modified time use fileatime() or filemtime(). It could presumably be helpful to determinate the timestamp of the newest file in a directory. (e.g. if you want to find out when the last change was made to your project). To get the modification date of some remote file, you have to use the fine operate by notepad at codewalker dot com . In addition to time-stamping internet articles, the filemtime() function can be used to select all articles older than a specified time for the aim of deleting all old articles.
This used static methods on the File and Directory objects. The FileTime utility makes use of these methods but provides some extra error checking and choices. You can view the supply code for FileTime which is on the market in automationControls. With the next perform you can set the date and time of all of the recordsdata and sub-directories inside a given directory. The perform takes a string that is the full path to a listing. It doesn’t examine whether this path represents a legitimate listing.
WordPress Development Stack Exchange is a question and answer site for WordPress builders and directors. Making statements based on opinion; back them up with references or personal expertise. The above code will show the modified date in month/day/year format. To make life easy unlockedcells.com bbb import the System.IO namespace into your code. The time resolution could differ from one file system to a different. I wanted the ability to seize the mod time of an image on a distant web site.
