If it’s a byte[] array: byte[] managedArray = new byte[size]; Marshal.Copy(pnt, managedArray, 0, size); If it’s not byte[], the size parameter in of Marshal.Copy is the number of elements in the array, not the byte size. So, if you had an int[] array rather than a byte[] array, you would have to divide by 4 …
array_of_hashes.any? {|h| h[:a] == 11}
use the JSON_FORCE_OBJECT option of json_encode: json_encode($status, JSON_FORCE_OBJECT); Documentation JSON_FORCE_OBJECT (integer) Outputs an object rather than an array when a non-associative array is used. Especially useful when the recipient of the output is expecting an object and the array is empty. Available since PHP 5.3.0. Or, if you want to preserve your “other” arrays inside …
Assuming $arr is the array, you can do like this: $computers = $arr | select -expand computer -unique $arr | group uid | ?{$_.count -eq $computers.count} | select name In general, I would approach union and intersection in Powershell like this: $a = (1,2,3,4) $b = (1,3,4,5) $a + $b | select -uniq #union $a …
Here is recursive solution: function combinations($arrays, $i = 0) { if (!isset($arrays[$i])) { return array(); } if ($i == count($arrays) – 1) { return $arrays[$i]; } // get combinations from subsequent arrays $tmp = combinations($arrays, $i + 1); $result = array(); // concat each array from tmp with each element from $arrays[$i] foreach ($arrays[$i] as …
By whitelisting the entries you do expect. <?php $post = array( ‘parent_id’ => 1, ‘type’ => ‘foo’, ‘title’ => ‘bar’, ‘body’ => ‘foo bar’, ‘tags’ => ‘foo, bar’, ‘one’ => ‘foo’, ‘two’ => ‘bar’, ‘three’ => ‘qux’ ); $whitelist = array( ‘parent_id’, ‘type’, ‘title’, ‘body’, ‘tags’ ); $filtered = array_intersect_key( $post, array_flip( $whitelist ) ); …
Try : $data = filter_input(INPUT_POST, ‘data’, FILTER_DEFAULT, FILTER_REQUIRE_ARRAY); Links: http://php.net/manual/en/function.filter-input.php http://php.net/manual/en/filter.filters.flags.php
Assuming you’re using .NET 3.5, you can turn any sequence (i.e. IEnumerable<T>) into a dictionary: var dictionary = sequence.ToDictionary(item => item.Key, item => item.Value) where Key and Value are the appropriate properties you want to act as the key and value. You can specify just one projection which is used for the key, if the …
Use Array.map to wrap each entry in quotes and then join them. var dates = [‘1/2/12′,’15/5/12’]; const datesWrappedInQuotes = dates.map(date => `’${date}’`); const withCommasInBetween = datesWrappedInQuotes.join(‘,’) console.log( withCommasInBetween );
Since this is still the top answer on google for adding tuples to an array, its worth noting that things have changed slightly in the latest release. namely: when declaring/instantiating arrays; the type is now nested within the braces: var stuff:[(name: String, value: Int)] = [] the compound assignment operator, +=, is now used for …
