Sending JSON Array via PHP (Campaign Monitor) - php

Question

I have a sample JSON Array labeled sample.txt that is sent from a sweepstakes form that captures a user's name and e-mail. I'm using WooBox so the JSON Array sends information over by each entry, so there are two entries here: http://pastebin.ca/3409546
On a previous question, I was told to break the ][ so that JSON_ENCODE can figure the separate entries. I would like to capture just the name and e-mail and import the array to my e-mail database (campaign monitor).
My question is: How do I add JSON variable labels to an array? If you see my code, I have tried to use the label $email. Is this the correct form or should it be email[0] with a for loop?
$url = 'http://www.mywebsite.com/sweeps/test.txt';
$content = file_get_contents($url);
$json = json_decode($content,true);
$tmp = explode('][', $json_string);
if (!count($tmp)) {
$json = json_decode($json_string);
var_dump($json);
} else {
foreach ($tmp as $json_part) {
$json = json_decode('['.rtrim(ltrim($json_string, '['), ']').']');
var_dump($json);
}
}
require_once 'csrest_general.php';
require_once 'csrest_subscribers.php';
$auth = array(
'api_key' => 'xxxxxxxxxxxxxxx');
$wrap = new CS_REST_Subscribers('xxxxxxxxxx', $auth);
$result = $wrap->add($json(
'EmailAddress' => $email,
'Name' => $custom_3_first,
'Resubscribe' => false
));

This should have been fairly easy: if you have a JSON string and you call json_decode($string, true) on it, you get its equivalent in a PHP variable, plain and simple. From there, you can access it like you would any PHP array, object, etc.
The problem is, you don't have a proper JSON string. You have a string that looks like JSON, but isn't valid JSON. Run it through a linter and you'll see what I mean.
PHP doesn't know what to do with your supposed JSON, so you have to resort to manual parsing, which is not a path I would recommend. Still, you were almost there.
require_once 'csrest_general.php';
require_once 'csrest_subscribers.php';
$auth = array('api_key' => 'xxxxxxxxxxxxxxx');
$wrap = new CS_REST_Subscribers('xxxxxxxxxx', $auth);
$url = 'http://www.mywebsite.com/sweeps/test.txt';
$content = file_get_contents($url);
$tmp = explode('][', $content);
foreach ($tmp as $json_part) {
$user = json_decode('['.rtrim(ltrim($json_string, '['), ']').']', true);
$result = $wrap->add(array(
'EmailAddress' => $user->email,
'Name' => $user->fullname,
'Resubscribe' => true
));
}
