Auto Description From Tags - php

Question

I'm trying to generate auto description from tags.
The code was working but after updating my site to Laravel 6 in stop working. I need to get it back working.
if( !empty( $request->description ) )
{
$description = Helper::checkTextDb($request->description);
}
else
{
$a_key = explode(",", strtolower($request->tags));
if(count($a_key) == 0)
$description = 'This is a great thing';
else
{
$description_get_keys = '';
foreach ($a_key as &$value)
{
if($value == end($a_key) && count($a_key) != 1)
$description_get_keys = $description_get_keys.' and '.$value.'.';
else if(count($a_key) == 1)
$description_get_keys = $value.'.';
else if (count($a_key) > 1 && $a_key[0] == $value)
$description_get_keys = $value;
else
$description_get_keys = $description_get_keys.', '.$value;
}
$description = 'This is a great thing about '.$description_get_keys;
}
}

I see a couple things that could possibly be an issue, not knowing what came before this code.
I will assume that the $request variable is an instance of Illuminate\Http\Request and that it is available in the function, right?
Try this updated code:
if($request->has('description'))
{
$description = Helper::checkTextDb($request->description);
}
else if ($request->has('tags'))
{
if (strpos($request->tags, ',') === false)
{
$description = 'This is a great thing';
}
else {
$a_key = explode(",", strtolower($request->tags));
$a_count = count($a_key);
$description_get_keys = '';
for ($i = 0; $i < $a_count; $i++)
{
if ($a_count == 1) {
$description_get_keys = "{$a_key[$i]}.";
}
else {
// first
if ($i === 0) {
$description_get_keys = $a_key[0];
}
// last
else if ($i === $a_count - 1) {
$description_get_keys .= " and {$a_key[$i]}.";
}
// middle
else {
$description_get_keys .= ", {$a_key[$i]}";
}
}
}
$description = "This is a great thing about {$description_get_keys}";
}
}
I wrote that quick so hopefully there are no errors.
