Foreach loop not displaying the 0 element in codeignter - php

Question

Goodday,
I need some assistant with my foreach loop.
I am uploading multiple images/files to my server and then i am trying to send the images as attachments in an email.
I get the data to the email function and can git it in the loop but for some reason i only see the last item in the array and con see why tjis is happing.
Please see attached the output and code of the function.
function forwardCallEmail($emaildetails)
{
$data = $emaildetails;
pre($data['files']);
echo('<br/>');
//die;
$CI = setProtocol();
$CI->email->from('');
$CI->email->subject("");
$CI->email->message($CI->load->view('calls/forwardCallEmail', $data, TRUE));
$path = base_url() . "uploads/Calls/";
foreach ((array) $data['files'] as $files){
echo($files);
echo('<br/>');
$images = explode(',', $files);
var_dump($images);
foreach($images as $files);
echo('<br/>');
echo $files;
die;
$CI->email->attach($path . $files);
pre($CI);
die;
}
$CI->email->to($data['email']);
$status = $CI->email->send();
return $status;

Answer 1

You can try something like this
Replace this part
foreach ((array) $data['files'] as $files){
echo($files);
echo('<br/>');
$images = explode(',', $files);
var_dump($images);
foreach($images as $files);
echo('<br/>');
echo $files;
die;
$CI->email->attach($path . $files);
pre($CI);
die;
}
To this one
foreach ((array) $data['files'] as $files){
echo($files);
echo('<br/>');
$images = explode(',', $files);
var_dump($images);
foreach($images as $files) {
echo('<br/>');
echo $files;
$CI->email->attach($path . $files);
pre($CI);
}
}
Anyway this example to explain a logic of foreach
Ok, just as example
$data = [
'files' => [
"image1, image2, image3",
"image4, image5, image6",
]
];
foreach ($data['files'] as $fileKey => $file){
echo($file);
$images = explode(',', $file);
foreach($images as $imageKey => $imageValue) {
$out[$fileKey][$imageKey] = $imageValue;
}
}
print_r($out);
And result will be
(
[0] => Array
(
[0] => image1
[1] => image2
[2] => image3
)
[1] => Array
(
[0] => image4
[1] => image5
[2] => image6
)
)

Answer 2

I got it to work, not sure if it is the right way it is working.
Email sending code
CI = setProtocol();
$CI->email->from('helpdesk#ziec.co.za', 'HTCC Helpdesk');
$CI->email->subject("HTCC Call Assistants");
$CI->email->message($CI->load->view('calls/forwardCallEmail', $data, TRUE));
$path = 'c:/xampp/htdocs/Helpdeskv2.1/uploads/Calls/';
$images = explode(',', $data['files']);
foreach($images as $file){
$path = 'c:/xampp/htdocs/Helpdeskv2.1/uploads/Calls/'. $file;
$CI->email->attach($path);
}
$CI->email->to($data['email']);
$status = $CI->email->send();
return $status;
