Take a look at array_count_values and arsort. <?php $myarray = array(“Human”,”Angel”,”God”,”Angel”,”Devil”,”God”,”God”,”Human”,”God”,”Angel”); $result = array_count_values($myarray); arsort($result); foreach($result as $word => $count) { echo $word.” was found “.$count.” time(s)<br/>”; } ?> solved PHP words array count
This is what I used to finish my project. public static bool Validate(int amount, int[] total, int[] needed) { int[] billCount = total; int[] cash = { 100, 50, 20, 10, 5, 1 }; int total = amount; bool isValid = true; for (int i = 0; i < total.Length; i++) { if(total >= cash[i]) … Read more
Notice that the object presented by @juvian does not have a defined ordering of the keys (in contrast to PHP associative arrays, for example). I guess you want an ordered collection, for which you have to use an array: var collection = [ {‘title’: ‘1’, ‘subtitle’:’sub1′, ‘contents’:’sub content 1′}, {‘title’: ‘2’, ‘subtitle’:’sub2′, ‘contents’:’sub content 2′}, … Read more
Just like I said I would, here your very own Json Object parser. One word of warning, these kind of things can be more art then science so if your inputs vary from what was in your example, it could have issues. Given the small sample size (1 document) I make no guarantees on it’s … Read more
Like this? $array->slug; It’s an object, not array. solved Access value from PHP array
If it is an Array of objects it will be initialized with null, if it’s an array of primitive values (like int) it will be initialized with 0. For the non-number primitive boolean it is false and for ‘char’ it is ‘\u0000’. For more information, check the table Default Values on the following page: http://docs.oracle.com/javase/tutorial/java/nutsandbolts/datatypes.html … Read more
result = input.map do |k, t| [k, DateTime.parse(t)] end.each_with_object(prev: nil, count: 0) do |(k, t), acc| case k # keep the time of the previous occurrence of “red” when “red” then acc[:prev] = t when “green” # seconds acc[:count] += 1 if 24.0 * 60 * 60 * (t – acc[:prev]) < 10 acc[:prev] = … Read more
the problem is you only unset a variable which has a copy of the value, you need to unset the corresponding element in the array. public function negativeKeywordsFilter($products, $negative_keywords){ $nk=explode(‘,’,$negative_keywords); foreach ($products[‘productItems’] as $key1 => $product){ foreach ($product as $key2 => $item){ foreach ($nk as $word){ if (stripos($item[‘name’],$word) !== false){ unset($products[‘productItems’][$key1][$key2]); } } } } … Read more
In C and C++, regular character strings are terminated by a ‘\0’ character. So it appears you are using a string function to copy the data. That is, it stops copying once it hits the ‘\0’ value. Interestingly, you left the part that copies the data (and maybe just the part the displays the data) … Read more
Solution without linq: int[] array1 = new int[] { 3, 5, 6, 9, 12, 14, 18, 20, 25, 28 }; int[] array2 = new int[] { 30, 32, 34, 36, 38, 40, 42, 44, 46, 48 }; int count1 = array1.Length; int count2 = array2.Length; int[] arrayResult = new int[count1 + count2]; int a = … Read more

foreach ($response[‘data’] as $data) { var_dump($data[‘ref’]); } solved PHP – retrieve data from an array
Car[] can contain only Car instances, or sub-classes of Car instances. If you were to have a class like this: class Honda extends Car , Honda instances can be populated in the Car array as well, because Honda extends from Car. Object[] can contain any Object instances, or any subclass of Object (every class in … Read more
Looks like a reasonably simple reduction (using array_reduce()) $x = array_reduce($x, function($arr, $val) { array_push($arr, $val, $val); return $arr; }, []); Demo ~ https://3v4l.org/eNH8a Just realised that “reduction” sounds a bit funny since we’re making the array bigger. Think of it more as a transformation. See https://en.wikipedia.org/wiki/Reduce_(parallel_pattern) 2 solved How to interleavedly duplicate an array … Read more
You can do with numpy and itertools: from numpy import linspace, prod from itertools import combinations arr = np.array([1,2,3,4]) [sum([prod(x) for x in combinations(arr,int(i))]) for i in linspace(1,len(arr), len(arr))] [10, 35, 50, 24] solved How to get sum of products of all combinations in an array in Python?
