1. Adding array elementsPHP is a weak type language, which means you don't need to display an array and its size, instead, you can declare and populate the array at the same time.
The code is as follows
Copy Code
$capitals = Array (' Alabama ' => ' Montgomery ',' Alaska ' => ' Juneau ',' Arizona ' => ' Phoenix ');
Additional array elements can be appended as follows:
$capitals [' Arkansas '] = ' Little rock '; I
1, add elements to the array
PHP is a weakly typed language. Therefore, you do not have to declare the length of the PHP array as the C language. The process of adding elements to them is also the process of declaring and initializing them.
Copy Code code as follows:
$capitals = Array (
' Alabama ' => ' Montgomery ',
' Alaska ' => ' Juneau ',
' Arizona ' => ' Phoenix '
);
It's also simple to continue adding elements
what is an array?
You will need to create many similar variables in the process of using PHP for development, either early or late.
Without a lot of similar variables, you can store the data in an array as an element.
Elements in the array have their own IDs, so they can be easily accessed.
Associative Arrays
An associative array in which each ID key is associated with a value.
Using numeric arrays is not the best practice when storing data about a specific named value.

("Griffin" =>array("Peter","Lois","Megan"),"Quagmire" =>array("Glenn"),"Brown" =>array("Cleveland","Loretta","Junior"));If you output this array, it should look something like this:
Array([Griffin] => Array([0] => Peter[1] => Lois[2] => Megan)[Quagmire] => Array([0] => Glenn)[Brown] => Array([0] => Cleveland[1] => Loretta[2] => Junior))Example 2Let's try to show a single value in the above array:
echo "is". $families [' Griffin '][2]."A part of the Griffin family";The output of the above code:

Associative arrays are a type of data that is often used when describing a set of keys and their associated values, which can be said to be the backbone of all programming languages, and of course, PHP is no exception, in fact, associative arrays are very important to web development tasks, and PHP supports a variety of ways to manipulate associative arrays, for developers, To figure out the most effective way to manipulate these arrays, the most appropriate method to develop your own program.
