Different between array and dynamic array in PHP

Static arrays, sometimes simply called arrays, are allocated with a fixed size.
Dynamic arrays increase their size when an insertion occurs and the array currently has no space for the new value.Usually the area doubles in size.
Static arrays are allocated memory at compile time and the memory is allocated on the stack.
The dynamic arrays are allocated memory at the runtime and the memory is allocated from heap.

1.Static arrays

Static variable initialized in constant. So while you may initialize a static property to an integer or array (for instance), you may not initialize it to another variable, to a function return value, or to an object.

class static_array {
    public $bar = "BIKE";
}

class myClass {
    static public $array = array();
    static public function init() {
        while ( count( self::$array ) < 3 )
            array_push( self::$array, new static_array() );
    }
}

myClass::init();
print_r( myClass::$array );

2. Dynamic arrays

Dynamic array is a special variable, which can hold more than one value at a time.

$color = array("blue","black","white","red","green");
print_r($color);
