As I noted in the comment to you, your example string is invalid. This example shows a valid string version of json. Use json_decode, with the 2nd parameter set to true to turn the embedded objects into array elements.
You will get an embedded array of arrays, but you can easily flatten that using the spread operator (...) with array_merge.
<?php
$string = '[{"006":"BASIC"},{"007":"ADV"}]';
$r = json_decode($string, true);
$r = array_merge(...$r);
print_r($r);
Outputs:
Array
(
[006] => BASIC
[007] => ADV
)

$string = '[{"006":"BASIC"}, {"007":"ADV"}, {"008":"ADV"}, {"009":"SUPER"}]';
var_dump(json_decode($string, true));
die;
Of if you need to join 2 arrays then you can first decode them and then merge them.
$stringOne = '[{"006":"BASIC"}, {"007":"ADV"}]';
$stringTwo = '[{"008":"ADV"}, {"009":"SUPER"}]';
$finalArray = array_merge(json_decode($stringOne, true), json_decode($stringTwo, true));
var_dump(json_encode($finalArray));
die;

Array to String Conversion Error
Don't use $email on lines 20-21 for the matches returned by preg_match() if you're also going to use $email to hold the email address. If preg_match() returns a match, $email will be a string (the email address), but if it doesn't return a match, $email will be an empty array. Reuse $matches instead. May also want to double-check that the variables for name, email address etc are being cleared out as you iterate through the while loop. More on reddit.com

March 12, 2018Warning: Array to string conversion in Variable method
What if you try $router->{$value['method']}( $value['path'], 'something' ); This is also how you should use array items within double quoted strings, think of it as how you use parenthesis in a math formula, to specify what parts go together. With your original code, PHP can't determine if $router->$value is an array and you are trying to access the 'method' element from that (what it seems to be assuming) versus that you are trying to use the 'method' element of value. wrapping it with the curly braces, ensures it knows you mean the later.
