PHP Arrays to JSON

gistfile1.php

<?php 

// This is how you would declare arrays in PHP (version 5.4+)
$someArray = [
    "first value",
    "second value"
];

// PHP Arrays are apparently also hash maps/dictionaries/whatever
$person = [
    "firstName" => "Mitchel",
    "lastName" => "Cabuloy"
];

echo $person["firstName"] . "\n";
echo $person["lastName"] . "\n";

// Let's add my age
$person["age"] = 21;

echo $person["age"] . "\n";

// Let's remove my age

unset($person["age"]);


// Let's do the questions example

$firstQuestion = [
    "header" => "The Best Header",
    "questions" => [
        "The Best Question",
        "The Second Best Question"
    ]
];

// Let's add this to an array

$questions = [];

$questions[] = $firstQuestion;

// Let's add another question. Note the syntax $question[] = $newObject;

$questions[] = [
    "header" => "Header Two",
    "questions" => [
        "Foo Question",
        "Bar Question"
    ]
];

// Here, I'm just printing it out.
foreach ($questions as $value) {
    echo $value["header"]."\n";

    foreach ($value["questions"] as $key => $value) {
        echo "[".$key."] ".$value."\n";
    }
}


// We can convert this array into JSON really easily!
$questionsInJsonFormat = json_encode($questions);

echo "Here's the JSON string\n";
echo $questionsInJsonFormat;

// This will make your life easier because you can create an array of questions, then convert it to JSON in just one line.
