Insert null or something if value of csv is null - php

Question

I have a problem uploading a csv to mysql.
I have the following csv.
I need to upload the marked fields the max fields the csv can contain are 48 but some csv contain only 36 or less. I have a form which if csv contains 48 cells uploads succesfully to mysql but if the csv is less than 48 I got error.
This is my form:
<div class="container">
<?php
if(isset($_POST['uploadBtn'])){
$fileName=$_FILES['myFile']['name'];
$fileTmpName=$_FILES['myFile']['tmp_name'];
$fileExtension=pathinfo($fileName,PATHINFO_EXTENSION);
$allowedType = array('csv');
if(!in_array($fileExtension,$allowedType)){?>
<div class="alert alert-danger">INVALID FILE</div>
<?php
}else{
$handle = fopen($fileTmpName, 'r');
$k = 0;
$hardness = array ();
while (($myData = fgetcsv($handle,1000,',')) !== FALSE) {
$k++;
if ( $k > 13 ) {
$hardness[] = $myData[3];
}
}
$query = "INSERT INTO metlab.resultados_dureza_junta

Answer 1

I would simply try padding your $myData with null
$myData = array_pad( $myData, 48, null );
realistically you should improve your SQL query to not process data that is missing, or review your default null value.

Answer 2

dirty solution but it works
$hardness = array (0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0);
