JSON Decode save array - php

Question

I am able to receive the following JSON data with the following PHP code:
$json = file_get_contents('https://xxxx');
$data = json_decode($json,true);
$forex = $data['items'];
echo "<pre>";
print_r($forex);
exit;
This gives me the following JSON data:
Array
(
[0] => Array
(
[new] =>
[data] => Array

[direction] => 1
[pip] => 0
[exchange] => FOREX

What I am trying to do is to save the information into my MySQL database, however I am unable to get the data displayed even by testing to echo the data:
foreach($forex as $info) {
echo $info->symbol . '<br>';
}
Anyone with a possible solution for me to save the data or even enable me to display the data for each Array (Example: symbol, pattern, link chart-md).

Answer 1

Below the commented code:
//Save json text into variable $json
$json = file_get_contents('https://xxxx');
//Convert json into PHP array
$data = json_decode($json,true);
//Set $forex as $data['items'];
$forex = $data['items'];
//Print
echo "<pre>";
print_r($forex);
exit;
$forex is a PHP array variable (not a JSON string).
You could save your data into MySQL VARCHAR[Length] field using json string variable $json instead of PHP array $forex.
When you need to get the data from DB and display it, you could get JSON data from MySQL and convert it from JSON to Array using PHP json_decode($json,true).
If you want to use a value into a PHP array, use $info["symbol"] instead of $info->symbol
