datetime - Why do I get 31 Dec 1969 as my last modified filename using filemtime in php? -

-

I'm a newbie to php and so please do not pay attention to asking me this question but why exactly filemtime (filename .txt) gives me its last revised time as 31 December, 196?

  • This means that your file was not found, either:

    • because it does not exist
    • or because it is not in the correct directory
    • or because you did not quote its name - you did not ^^

    The date of January 1, 1970 is the date of "zero";

    So, December 31, 1969 is the date / time of zero ... according to your location, I think; I myself, with this code: 

      $ filemtime = filemtime (filename.txt); $ Formated = date ('y-m-d h: i: s', $ filemtime); Var_dump ($ filemtime, $ formated);

    Obtain this output: 

      Boolean false string '1 971-01-01 01:00:00' (length = 19)

    false because the file does not exist, and 1970-01-01 at 01:00 due to my location (I I am in France, UTC + 1 hour)


    And note that I also get some notices and warnings:

    • NOTICE: Use Undefined Continuous Filename - Assumed 'Filename'
    • Notice: Undefined Use of TextType - Assumed 'txt'
    • Warning: Filemtime () [function.filemtime]: failed for stat filenametxt
      • < / Ul>

      Do you have any of these?
      If not, then is error_reporting and / or display_errors enabled?

    c# - How to capture HTTP packet with SharpPcap -

    -
    I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes. All st...
