c - How do I use Minizip (on Zlib)? -


i'm trying archive files cross-platform application, , looks minizip (built on zlib) portable archivers come.

when try run following dummy code, however, system error [my executable] has stopped working. windows can check online solution problem.

can me see how use library? — (there's no doc or tutorial anywhere can find)

zip_fileinfo zfi; int main() { zipfile zf = zipopen("myarch.zip",append_status_addinzip); int ret = zipopennewfileinzip(zf, "myfile.txt", &zfi, null, 0, null, 0, "my comment interior file", z_deflated, z_no_compression ); zipclosefileinzip(zf); zipclose(zf, "my comment exterior file"); return 0; }

specs: msys + mingw, windows 7, using zlibwapi.dll zlib125dll.zip/dll32

since found question via google , didn't contain complete, working code, providing here future visitors.

int createzipfile (std::vector<wstring> paths) { zipfile zf = zipopen(std::string(destinationpath.begin(), destinationpath.end()).c_str(), append_status_create); if (zf == null) return 1; bool _return = true; (size_t = 0; < paths.size(); i++) { std::fstream file(paths[i].c_str(), std::ios::binary | std::ios::in); if (file.is_open()) { file.seekg(0, std::ios::end); long size = file.tellg(); file.seekg(0, std::ios::beg); std::vector<char> buffer(size); if (size == 0 || file.read(&buffer[0], size)) { zip_fileinfo zfi = { 0 }; std::wstring filename = paths[i].substr(paths[i].rfind('\\')+1); if (s_ok == zipopennewfileinzip(zf, std::string(filename.begin(), filename.end()).c_str(), &zfi, null, 0, null, 0, null, z_deflated, z_default_compression)) { if (zipwriteinfileinzip(zf, size == 0 ? "" : &buffer[0], size)) _return = false; if (zipclosefileinzip(zf)) _return = false; file.close(); continue; } } file.close(); } _return = false; } if (zipclose(zf, null)) return 3; if (!_return) return 4; return s_ok; }

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
