PHP - Using Curl For Database Matching

I'm working a membership application page for my amateur radio club. I'm currently stumped passing a variable from HTML to PHP.  The variable is called "nametag" and it's a "radio" type.

No Matter if I select 10 or 0. I still get 15 being passed to PHP. 

Any help is appreciated.

Thanks

I wish to find the closest two DateTimes which are within $fillStart and $fillEnd and have the same week and 24 hour times as $gapStart and $gapEnd.

For instance, the following results in $fillStartModified and $fillEndModified which meets that criteria.

fillStart           2019-07-23 00:15:00 Tue
fillEnd             2019-09-23 13:00:00 Mon
gapStart            2019-05-23 00:15:00 Thu
gapEnd              2019-06-23 13:00:00 Sun
fillStartModified   2019-07-25 00:15:00 Thu
fillEndModified     2019-08-25 13:00:00 Sun

I came up with the following which seems to work, but it is kind of complicated and I am not positive it will meet all edge conditions.  Any recommendations?  Thanks

function getFill(\DateTimeImmutable $fillStart, \DateTimeImmutable $fillEnd, \DateTimeInterface $gapStart, \DateTimeInterface $gapEnd)
{
    //$gapInterval = $gapStart->diff($gapEnd);  // Doesn't work 
    $gapInterval = new \DateInterval('PT'.($gapEnd->getTimestamp() - $gapStart->getTimestamp()).'S');
    if($gapStart > $fillStart) {
        //The fill is older than the gap so make the fill's endTime match the gap's endTime
        $fillEndModified = $fillEnd
        ->modify('previous '.$gapEnd->format('D'))
        ->setTime(...explode('.', $gapEnd->format('H.i.s.u')));
        if($fillEndModified->diff($fillEnd)->format('%a') >= 7) {
            $fillEndModified = $fillEndModified->add(new \DateInterval('P7D'));
        }
        $fillStartModified = $fillEndModified->sub($gapInterval);
        if($fillStartModified < $fillStart) {
            $fillStartModified=null;
            $fillEndModified=null;
        }
    }
    else {
        //The fill is newer than the gap so make the fill's startTime match the gap's startTime
        $fillStartModified = $fillStart
        ->modify('next '.$gapStart->format('D'))
        ->setTime(...explode('.', $gapStart->format('H.i.s.u')));
        if($fillStart->diff($fillStartModified)->format('%a') >= 7) {
            $fillStartModified = $fillStartModified->sub(new \DateInterval('P7D'));
        }
        $fillEndModified = $fillStartModified->add($gapInterval);
        if($fillEndModified > $fillEnd) {
            $fillStartModified=null;
            $fillEndModified=null;
        }
    }
    return [$fillStartModified, $fillEndModified];
}

Hello group.

I need some help with my code.

<?php
 

$a1 = array("line1"=>"1-2-3-10-14","line2"=>"1-2-3-10-34","line3"=>"1-2-7-16-35","line4"=>"1-2-3-17-19","line5"=>"2-5-11-15-32");
$a2 = array("inputnumber"=>"1-2-3-10-34");

$result = array_intersect($a1,$a2);
print_r($result);

?>

Right now, I can only search and find an exact match of all 5-Numbers. I want to code a PHP form that will take a (5-number string) as input and then compare that string against an array database of (5-number strings) to find all matching number occurrences for each “LINE 1 thru LINE 5”. 

For instance, if I were to type the 5-number string “1-2-3-10-34” as input.  The Output populated results would look like this ..

<?php
$password = "Fyfjk34sdfjfsjq7";

if (preg_match("/^.*(?=.{8,})(?=.*\d)(?=.*[a-z])(?=.*[A-Z]).*$/", $password)) {
    echo "Your passwords is strong.";
} else {
    echo "Your password is weak.";
}
?>

Hi everyone,

My code is meant to give a certain response if the hospital number & PIN together do or do not match.

However, whatever I input, whether it is correct information or random numbers, I still get the output that the data has been submitted successfully.

Any thoughts?

<?php  

$connect = mysqli_connect($hostname, $username, $password, $databaseName);

    $query = "UPDATE card SET comments = '$comments' , seniorsent = '$seniorsent' WHERE hospitalnumber = '$hospitalnumber' and PIN = '$PIN'";
    @mysqli_query($connect, $query);

  $result = mysqli_query($connect, $query);

   if($result)
   {
       echo 'Data submitted successfully';
   }else{
       echo 'Please check that all details are correct';
   }

Thanks in advance,
