Let's say you want to create the following key:value pairs.

Arrays are used to create key value pairs.

$array = array(
    "name" => "Jeremy",
    "id" => "123456",
    "occupation" => "engineer"
);

var_dump can be used to print the data structure of the array.

var_dump($fruit);

Which will return the following.

array(3) { [name]=> string(6) "Jeremy" [id]=> string(6) "123456" [occupation]=> string(8) "engineer" }

Specific elements can be printed, like this.

echo "array[name]       = " . $array[name] . "<br />";
echo "array[id]         = " . $array[id] . "<br />";
echo "array[occupation] = " . $array[occupation] . "<br />";

Which will return the following.

array[name] = Jeremy
array[id] = 123456
array[occupation] = engineer

Or you can loop through the array.

foreach ($array as $value) {
  echo "$value<br \>";
}

Which will return the following.

Jeremy
123456
engineer

And here is how to print both the keys and values.

foreach ($array as $key => $value) {
  echo $key . ' = ' . $value . '<br \>';
}

Which should return the following.

Name = Jeremy
ID = 123456
Occupation = engineer
