c# - Most efficient way for reading IMDB movies list -


i reading imdb movies listing text file on harddrive (originally available imdb site @ ftp://ftp.fu-berlin.de/pub/misc/movies/database/movies.list.gz).

it takes around 5 minutes on machine (basic info: win7 x64bit, 16gb ram, 500 gb sata hardisk 7200 rpm) read file line line using code below.

i have 2 questions:

  1. is there way can optimize code improve read time?

  2. data access don't need sequential won't mind reading data top bottom / bottom top or order matter long read 1 line @ time. wondering there way read in multiple directions improve read time?

the application windows console application.

update: many responses correctly pointed out writing console takes substantial time. considering displaying of data on windows console desirable not mandatory.

//code block

string file = @"d:\movies.list"; filestream fs = new filestream(file, filemode.open, fileaccess.read, fileshare.none, 8, fileoptions.none); using (streamreader sr = new streamreader(fs)) { while (sr.peek() >= 0) { console.writeline(sr.readline()); } }

i'm not whether more efficient or not, alternate method use file.readalllines:

var moviefile = file.readalllines(file); foreach (var movie in moviefile) console.writeline(movie);

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
