How to Convert a Multidimensional PHP Array to a JSON String?

Generate JSON String from Multidimensional Array Data

In PHP, the json_encode() function can be utilized to convert multidimensional arrays into valid JSON strings. Below is an example:

<?php
// Assuming the following array
$array = array(
    array(
        'oV' => 'myfirstvalue',
        'oT' => 'myfirsttext',
    ),
    array(
        'oV' => 'mysecondvalue',
        'oT' => 'mysecondtext',
    ),
);

// Encode the array to JSON
$json = json_encode($array);

// Output the JSON string
echo $json;
?>

The output of the provided example will be:

[{"oV":"myfirstvalue","oT":"myfirsttext"},{"oV":"mysecondvalue","oT":"mysecondtext"}]

It's important to verify that the JSON string is valid. Proper JSON syntax requires double quotes around the object property names and string values.
