Error in Laravel vendor files: Warning: Unsupported declare 'strict_types' in Laravel 5.3

For some reason on my Laravel 5.3 application when I run composer update I get the following error

Warning: Unsupported declare 'strict_types' in /home/site/public_html/bookings/vendor/league/csv/src/functions.php on line 13

I think it may have to do with the PHP Version as its not recognizing the PHP 7 typing constructs, I am running PHP 7.0.25 on my server however when I run php -v in my console when I ssh into the server it shows PHP 5.6.32.

Anyone have any idea why its moaning about this core file? I have not touched any of the files in the vendor folder.

Here is the contents of that file:

{
    static $list;

    $list = $list ?? (new ReflectionClass(ByteSequence::class))->getConstants();

    foreach ($list as $sequence) {
        if (0 === strpos($str, $sequence)) {
            return $sequence;
        }
    }

    return '';
}

{
    $found = array_unique(array_filter($delimiters, function (string $value): bool {
        return 1 == strlen($value);
    }));
    $stmt = (new Statement())->limit($limit)->where(function (array $record): bool {
        return count($record) > 1;
    });
    $reducer = function (array $result, string $delimiter) use ($csv, $stmt): array {
        $result[$delimiter] = count(iterator_to_array($stmt->process($csv->setDelimiter($delimiter)), false), COUNT_RECURSIVE);

        return $result;
    };
    $delimiter = $csv->getDelimiter();
    $header_offset = $csv->getHeaderOffset();

    }
}

Your servers web has PHP 7 enabled (if you took it from phpinfo();), but CLI of your server doesn't. The command you are trying to run is being run from console.

CLI and WEB PHP versions are differn't things.

If your server is Debian based (Ubuntu). Look into /etc/php and see if there are multiple PHP versions, if there are, you can make symbolic link to link your CLI version also to PHP 7

sudo ln -sfn /usr/bin/php7.0 /usr/bin/php
