क्या आप वास्तव में जानते हैं कि सरणियाँ क्या हैं?

Arrays और उनकी मूल भाषा - C

int myArray[10];
int fibonacci[10] = {0, 1, 1, 2, 3, 5, 8, 13, 21, 34};

int i, sum;
for (i = 0; i < 9; i++) {
  sum += fibonacci[i];
}

जावास्क्रिप्ट सरण

let myArray = [];
let fibonacci = [0, 1, 1, 2, 3, 5, 8, 13, 21, 34];

myArray[0] = 5;
myArray[1] = 5.5;
myArray[2] = 'cat';
myArray[3] = [1,2,3];
myArray[4] = (a,b) => {a+b};
myArray[1000] = 'mind blown';
// myArray = [5, 5.5, 'cat', [1,2,3], (a,b) => {a+b}];

let sum = 0;
for (i = 0; i < fibonacci.length; i++) {
  sum += fibonacci[i];
}

let sum = fibonacci
   .filter(Number.isInteger)
   .reduce(
      (x,y) => {return x+y}, 0
    );

PHP में आता है

$myArray = [];
$fibonacci = [0, 1, 1, 2, 3, 5, 8, 13, 21, 34];
$myArray[0] = 5;
$myArray[1] = 5.5;
$myArray[2] = 'cat';
$myArray[3] = [1,2,3];
$myArray[4] = function($a, $b) { return $a + $b; };

$myArray['banana'] = 'yellow fruit';
$myArray[5] = 'is alive';
$myArray[0.02] = 'the 2%';

$colours = [
  'red' => '#FF0000',
  'green' => '#00FF00',
  'blue' => '#0000FF',
  'orange' => '#FF6600',
];

$users = [
  1 => 'Andi',
  2 => 'Benny',
  3 => 'Cara',
  4 => 'Danny',
  5 => 'Emily',
];
$lookupTable = array_flip($users);
return $lookupTable['Benny'];

$sum = 0;
foreach ($myArray as $key => $value) {
  $sum += is_numeric($value) ? $value : 0;
}

$sum = 
  array_reduce(
    array_filter($fibonacci, 'is_numeric'),
    function ($x, $y) { return $x + $y; },
    0
  };
