Step by Step solution about How to resolve the algorithm Hash from two arrays step by step in the PHP programming language

Using the Built-in array_combine() Function:

• The array_combine() function takes two arrays, keys and values, and creates a new array with the keys from the first array and the values from the second array.
• In the first example, the $keys and $values arrays are both initialized with three elements.
• The array_combine() function is then called with these two arrays as arguments, and it creates a new array, $hash, with the following key-value pairs:
  • "a" => 1
  • "b" => 2
  • "c" => 3

Manually Creating the Hash Map:

• The second example shows how to manually create a hash map using a loop.
• This approach is less efficient than using the array_combine() function, especially for large arrays.
• A for loop is used to iterate over the $keys and $values arrays, and for each index, the corresponding key and value are added to the $hash array.
• The resulting $hash array is the same as the one created using the array_combine() function.

$keys = array('a', 'b', 'c');
$values = array(1, 2, 3);
$hash = array_combine($keys, $values);


$keys = array('a', 'b', 'c');
$values = array(1, 2, 3);
$hash = array();
for ($idx = 0; $idx < count($keys); $idx++) {
  $hash[$keys[$idx]] = $values[$idx];
}
