PHP arrays: indexed, associative and foreach without confusion

Most PHP beginners do not struggle because arrays are hard.

They struggle because three ideas arrive at the same time:

• indexed arrays
• associative arrays
• foreach

Indexed array:

$languages = ["PHP", "JavaScript", "Python"];
echo $languages[0];

Associative array:

$user = [
    "name" => "Nadia",
    "role" => "developer"
];

echo $user["name"];

Foreach with values:

foreach ($languages as $language) {
    echo $language;
}

Foreach with keys and values:

foreach ($user as $key => $value) {
    echo $key . ": " . $value;
}

The key idea: => links a key to a value.
