How to print out associative arrays in PHP?

Associative arrays can be iterated through with a foreach loop to output values, or specific values can be accessed using keys. Here are some examples:

1. Display all values of an associative array using a foreach loop.

$fruits = array("apple" => "red", "banana" => "yellow", "orange" => "orange");

foreach($fruits as $key => $value) {
    echo "The color of $key is $value <br>";
}

The output is:

The color of apple is red
The color of banana is yellow
The color of orange is orange

1. Access specific values using key-value pairs.

$fruits = array("apple" => "red", "banana" => "yellow", "orange" => "orange");

echo "The color of apple is " . $fruits["apple"];

Output result:

The color of apple is red

With the above method, it is easy to output the values of an associative array.
