Example 1In this example, the ID key is automatically assigned:
The Code is as follows:
Copy code
$ Names = array ("Peter", "Quagmire", "Joe ");
Example 2In this example, we manually allocate the ID key:
The Code is as follows:
Copy code
$ Names [0] = "Peter ";$ Names [1] = "Quagmire ";$ Names [2] = "Joe ";
You can use these ID keys in the script:
The Code is as follows:

$names = Array ("Peter", "Quagmire", "Joe");
Example 2In this example, we manually assign the ID key:
The code is as follows
Copy Code
$names [0] = "Peter";$names [1] = "quagmire";$names [2] = "Joe";
