The problem was that fopen was failing when trying to access a file as a URL through apache -- even though it worked fine when run from the shell and even though the file was readily readable from any browser. This is true whether it's opened in "r" or "w" mode. See man 7 fifo: this is the correct, default behaviour; although Linux supports non-blocking fopen of a fifo, PHP doesn't.
This functions check recursive permissions and recursive existence parent folders, before creating a folder. Got to know that it uses windows Used iconv to convert it to UTF-8 and it resolved the issue. PHP will open a directory if a path with no file name is supplied. This just bit me. I was not checking the filename part of a concatenated string. I tried append mode and it errors out so does not seem to be dangerous. This is with FreeBSD 4. Behaves the same on 4.
I was working on a consol script for win32 and noticed a few things about it. On win32 it appears that you can't re-open the input stream for reading, but rather you have to open it once, and read from there on. Also, i don't know if this is a bug or what but it appears that fgets reads until the new line anyway.
The number of characters returned is ok, but it will not halt reading and return to the script. I don't know of a work around for this right now, but i'll keep working on it. This is some code to work around the close and re-open of stdin. Which contains an array of the response header. Also avoid these names followed immediately by an extension; for example, NUL. It specifies the file which you want to check. Return Value: It returns the last time of a file when its content was modified as a Unix Timestamp on success and False on failure.
Skip to content. Change Language. Related Articles. Table of Contents. Save Article. This function returns the time when the data blocks of a file were being written to, that is, the time when the content of the file was changed.

Improve this question. This is a very handy function for dealing with browser caching. For example, say you have a stylesheet and you want to make sure everyone has the most recent version. You could rename it every time you edit it, but that would be a pain in the ass. This comes in handy when you want just one 'last updated' message on the frontpage of your website and still taking all files of your website into account. Regards, Frank Keijzers. For example the command "touch directory" updates the timestamp of a directory without file creation.
Also file removal will update the timestamp of a directory. A comment below states "When using this function to get the modified date of a directory, it returns the date of the file in that directory that was last modified.
Another little handy tool; to get the most recent modified time from files in a directory. The snippet of code earlier that allows you to delete all files older than 2 weeks uses the function filemtime - which checks the original create date of the file filesystem independent. While testing on Windows, I noticed that the precision of filemtime is just 1 second.
So if you use clearstatcache and filemtime to check if a file has been modified, it might fail to detect the change. The modifications just have to happen within less than a second.
