How to Access Values from Multi-Dimensional PHP Arrays

You're confronted with a multi-dimensional PHP array, as shown by print_r($myarray), and you're eager to retrieve specific values like the email or gender.

Solution:

To access values within a multi-dimensional array, navigate through its dimensions by specifying the array key at each level. For example:

<code class="php">echo $myarray[0]['email']; // prints "[email protected]"
echo $myarray[0]['gender']; // prints "male"</code>

Examine the keys and indentations in the output of print_r:

<code class="php">$myarray = Array
(
    [0] => Array
    (
        [id] => 6578765
        [name] => John Smith
        [first_name] => John
        [last_name] => Smith
        [link] => http://www.example.com
        [gender] => male
        [email] => [email protected]
        [timezone] => 8
        [updated_time] => 2010-12-07T21:02:21+0000
    )
)</code>

You can deduce that the first element ([0]) is a subarray containing the user data, and its keys specify the attributes (e.g., email, gender).
