Create an array of a specific type and size

Create an indexed array with the specified type and number of elements. An indexed array is a more efficient way to store variables in memory if the size and data type is known beforehand. The array() function creates a hashed array, which consumes much more memory per element.

$type: 1=byte, 2=short, 3=int, 4=float

• Type 1: Array of bytes
• Type 2: Array of short integers (16 bits)
• Type 3: Array of 32 bit integers
• Type 4: Array of floating point numbers

$size: The number of elements in the array

Indexed array

<? 
  $arr=indexed_array(1,100); // create an array of 100 bytes
?>

There are no named keys in an indexed array, all elements are referenced by the index number. The first element is index=0, and the last element is index=$size-1.
