I'm working on Laravel (v5.7) app that converts uploaded CSV (with contacts) into array that is then passed as argument when job class is being dispatched.
Here is the example of CSV file (format that is supported):
123456,Richard,Smith
654321,John,Doe
Uploaded (CSV) file is handled like this:
$file_path = $request->file_name->store('contacts');
$file = storage_path('app/' . $file_path);
$contactsIterator = $this->getContacts($file);
$contacts = iterator_to_array($contactsIterator); // Array of contacts from uploaded CSV file
protected function getContacts($file)
{
$f = fopen($file, 'r');
while ($line = fgets($f))
{
$row = explode(",", $line);
yield [
'phone' => !empty($row[0]) ? trim($row[0]) : '',
'firstname' => !empty($row[1]) ? trim($row[1]) : '',
'lastname' => !empty($row[2]) ? trim($row[2]) : '',
];
}
}
Finally, $contacts
array is passed to a job that is dispatched:
ImportContacts::dispatch($contacts);
This job class looks like this:
public function __construct($contacts)
{
Log::info('ImportContacts@__construct START');
$this->contacts = $contacts;
Log::info('ImportContacts@__construct END');
}
public function handle()
{
Log::info('ImportContacts@handle');
}
... and everything worked fine (no errors) until I've tried with this CSV:
123456,Richardÿ,Smith
654321,John,Doe
Please notice ÿ
. So, when I try with this CSV - I get this error exception:
/code_smsto/vendor/laravel/framework/src/Illuminate/Queue/Queue.php | 91 | Unable to JSON encode payload. Error code: 5
... and my log file looks like this:
error local 2019-11-11 17:17:18 /code_smsto/vendor/laravel/framework/src/Illuminate/Queue/Queue.php | 91 | Unable to JSON encode payload. Error code: 5
info local 2019-11-11 17:17:18 ImportContacts@__construct END
info local 2019-11-11 17:17:18 ImportContacts@__construct START
As you can see - handle
method was never executed. If I remove ÿ
- no errors and handle
is executed.
utf8_encode
: protected function getContacts($file, $listId)
{
$f = fopen($file, 'r');
while ($line = fgets($f))
{
$row = explode(",", $line);
yield [
'phone' => !empty($row[0]) ? utf8_encode($row[0]) : '',
'firstname' => !empty($row[1]) ? utf8_encode($row[1]) : '',
'lastname' => !empty($row[2]) ? utf8_encode($row[2]) : '',
];
}
}
... and it works (no errors, no matter if there's that ÿ
), but then Greek and Cyrillic letters are turned into question marks. For example, this: Εθνικής
will become ???????
.
I also tried with mb_convert_encoding($row[1], 'utf-8')
- and it doesn't turn Greek or Cyrillic letter into question marks, but this ÿ
character will become ?
.
@handle
method of a Job class worked, but then I was not able to store the data from that array into DB (MongoDB). Please see the update below.This is what I get from dd($contacts);
:
So, it has that "b" where ÿ
is. And, after some "googling" I found that this "b" means "binary string", that is, a non unicode string, on which functions operate at the byte level (What does the b in front of string literals do?).
What I understand is this: When dispatching Job class, Laravel tries to "JSON encode" it (passed arguments/data) but it fails because there are binary data (non-unicode strings).
Anyway, I was not able to find a solution (to be able to handle such CSV file with ÿ
).
I am using:
When I move "handling" (converting to array) of uploaded CSV file into @handle
method of a Job class - I don't get this error (Unable to JSON encode payload. Error code: 5
), but when I try to store that problematic binary data with ÿ
(b"Richardÿ"
) into MongoDB - it fails. The weird thing is that I don't get any error-exception message in log file, so I put all in try-catch like this:
try {
// Insert data into MongoDB
} catch (Exception $e) {
Log::info($e->getFile());
Log::info($e->getLine());
Log::info($e->getMessage());
}
... and this is the result:
Anyway, I believe that it failed because of b"Richardÿ"
, and I guess that the solution is in encoding string, but as I've mentioned - I was not able to find a solution that works:
utf8_encode
works (no errors, no matter if there's that ÿ
), but then Greek and Cyrillic letters are turned into question marks. For example, this: Εθνικής
will become ???????
mb_convert_encoding($row[1], 'utf-8')
- it doesn't turn Greek or Cyrillic letter into question marks, but this ÿ
character will become ?
.iconv('windows-1252', 'UTF-8', $row[1])
- works (no errors, no matter if there's that ÿ
), but when there are Greek or Cyrillic letters - it fails (I get this error exception: iconv(): Detected an illegal character in input string

In the current stable, PHP v7.2, if you want to determine if JSON is invalid, you have to use the json_last_error () function to verify: For example, in the Laravel Illuminate\Encryption\Encrypter class here’s a check to make sure calling json_encode () doesn’t result in an error:
We can at least determine if JSON encoding/decoding had an error, but it’s a little clunky compared to throwing an exception, which packages the error code and message neatly together. Although you have to opt-in, v7.3 has an excellent way of allowing you to catch and handle JSON exceptions—let’s check out the new flag we can use!
PHP 7.3: A Look at JSON Error Handling. One of the new features coming to PHP 7.3 is better error handling for json_encode() and json_decode(). The RFC was unanimously accepted by a 23 to 0 vote.
You have several ways to deal with it but I'd recommend the following two. In both cases, the idea is that you store a UTF-8 string.
A simpler approach, figure out what encoding it is out of the (your) predefined list and convert it to UTF8.
$encoding = mb_detect_encoding($content, 'UTF-8, ISO-8859-1, WINDOWS-1252, WINDOWS-1251', true);
if ($encoding != 'UTF-8') {
$string = iconv($encoding, 'UTF-8//IGNORE', $row[1]);
}
The second approach is to use a third party library outlined in this answer
