linux - PHP fwrite doesn't update the file using the append mode -

-

the following code working doesn't update contents of file created.

i can see file contents have changed (the size increased) when download file server it's empty. file chmod 666 , parent directory well.

its linux server running apache , php. i've tried using fflush force flush contents.

<?php  header("location: http://www.example.com"); $handle = fopen("log.txt", "a"); foreach($_post $variable => $value) {    fwrite($handle, $variable);    fwrite($handle, '=');    fwrite($handle, $value);    fwrite($handle, '\r\n'); }  fwrite($handle, '\r\n'); fflush($handle); fclose($handle);  ?>

what problem?

thanks!

i think practice check if file writable is_writable if can opened checking value returned fopen, way code right.

try this:

$filename = "log.txt"; $mode = "a"; // let's make sure file exists , writable first. if (is_writable($filename)) {      // in our example we're opening $filename in append mode.     // file pointer @ bottom of file hence     // that's $somecontent go when fwrite() it.     if (!$handle = fopen($filename, $mode)) {          echo "cannot open file ($filename)";          exit;     }      foreach($_post $variable => $value) {        fwrite($handle, $variable);        fwrite($handle, '=');        fwrite($handle, $value);        fwrite($handle, '\r\n');     }      fwrite($handle, '\r\n');     fflush($handle);     fclose($handle);     echo "content written file ($filename)";  } else {     echo "the file $filename not writable"; }

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

cgi - How do I interpret URLs without extension as files rather than missing directories in nginx? -

-
so i'm trying install zoneminder , have run under nginx, has few compiled files need run using fast-cgi. these files lack extension. if file has extension, there no issue , nginx interprets file , return 404 if can't find it. if has no extension, assume it's directory , return 404 when can't find sort of index page. here have now: # security camera domain. server { listen 888; server_name mydomain.com; root /srv/http/zm; # enable php support. include php.conf; location / { index index.html index.htm index.php; } # enable cgi support. location ~ ^/cgi-bin/(.+)$ { alias /srv/cgi-bin/zm/; fastcgi_pass unix:/run/fcgiwrap.sock; fastcgi_param script_filename $document_root/$1; include fastcgi.conf; } } the idea is, under cgi-bin directory goes through fastcgi pipe. any idea on howi can fix this? upon closer inspection, realized zoneminder has 2 cgi sc...
