包含许多值或多个变量的数组，每个变量都有一个值？ [关闭]

Question

Which option is better to save server resources: Array with many values or many variables, each with one value?

Latter the array values will plan to use like this: array($input[0], array($input[3], array($input[10].

Variables: $input0, $input0, $input10.

Which option is better to save server resources (is it worth to pay attention at all)?

Answer 1

If you plan on referring to a set of variables as a group you would need an array. Other options would be variable variables or string interpolation such as

$input0 = 'a';
$input1 = 'b';
$input2 = 'c';

// Note you must know the number of 'input' variables ahead of time...
for($i=0; $i<3; $i++)
  echo "$input${i}";

Nothing short of atrocious IMO.
