PHP arrays can be initialized in several ways without declaring their type.
Because PHP is dynamically typed, an array or its element type does not need to be declared.
Arrays can be initialized using the array() function.
An empty array is created with $arr = array();
An array can be initialized with elements supplied as function arguments, such as $arr = array(10, 20, 30);
An array can contain mixed types, such as integers, floating-point numbers, and strings.
Array elements use zero-based indexing by default.
In the examples, the elements are located at indices 0, 1, and 2.
Square bracket syntax is used to access and assign array elements.

"Since PHP is dynamically typed, you do not need to declare an array or specify a particular type of variable that it holds. However, there are several ways that you can initialize an array. To create an empty array, you can call the array() function. Optionally, you can provide an initial list of elements to insert into the array by providing the list of elements as arguments to the function.\n\n1 //create an empty array:\n\n2 $arr = array();\n\n3\n\n4 //create an array with elements 10, 20, 30:\n\n5 $arr = array(10, 20, 30);\n\n6\n\n7 //create an array with mixed types:\n\n8 $arr = array(10, 3.14, \"Hello\");\n\nBy default, when inserting elements, 0-indexing is used. In the three examples above, each element would be located at indices 0, 1, and 2 respectively. The usual square bracket syntax can be used to access and assign elements."
