php - Split one file and make them into two - 


//expression found in file name $find = '.5010.';  //directory name //we store renamed files here $dirname = '5010'; if(!is_dir($dirname))     mkdir($dirname, 0777);  //read files directory //skip directories $directory_with_files = './'; $dh  = opendir($directory_with_files); $files = array(); while (false !== ($filename = readdir($dh))) {     if(in_array($filename, array('.', '..')) || is_dir($filename))         continue;      $files[] = $filename; }  //iterate collected files foreach($files $file) {     //check if file name matching $find     if(stripos($file, $find) !== false)     {          //open file         $handle = fopen($file, "r");         if ($handle)         {             //read file, line line             while (($line = fgets($handle)) !== false)             {                  //find ref line                 $refid = 'ref*2u*';                  if(stripos($line, $refid) !== false)                      {                      //glue refernce numbers                      //check if reference number not empty                       $refnumber = str_replace(array($refid, '~'), array('', ''), $line);                 if($refnumber != '')                      {                  $refnumber = '_'. $refnumber .'_';                   $filerenamed = str_replace($find, $refnumber, $file);                      copy($file, $dirname . '/' . $filerenamed);                          }                   echo $refnumber . "\n";                      }             }              //close file             fclose($handle);         }     } }

i have code above, read files contain ".5010." , replace characters after ref*2u*. in files there more 1 ref*2u*, there code split them through line called "n1*pr*" , output 2 files each own ref*2u* character?

stream_get_line trick string stream_get_line ( resource $handle , int $length [, string $ending ] )

quoting documentation,

reading ends when length bytes have been read, when string specified ending found (which not included in return value), or on eof (whichever comes first).

so looping through lines of file checking fro specific string follows example:

$i = 1; while(! feof($file)) {     $contents = stream_get_line($file,1000,"ref*2u*");     file_put_contents('new_file_'.$i.'.txt',$contents);     $i++; }

amazon web services - S3 Pre-signed POST validate file type? -

i know it's possible put limit on file size content-length-range header. possible validate file type? https://docs.aws.amazon.com/amazons3/latest/dev/httppostforms.html#policyconditions i see there content-type header, if set say, audio/mp3 allow mp3 files , return error if file not mp3? i found previous question answers mention validating file size: s3 direct upload restricting file size , type you can specify content-type @ post request. you can specify @ signature, post must done content-type: { "expiration": "2007-12-01t12:00:00.000z", "conditions": [ {"acl": "public-read" }, {"bucket": "johnsmith" }, {"content-type: "audio/mp3"} ] } creating html form (using aws signature version 4) edit: @ previous question found, checking content-type.

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
