I have a code with an array that saves what i need each time I press a button, so these items saved into an array I showed later with a erase buttons, but I don't know how to delete it, so there is the part of the code that shows what I meant:

echo "<table border=1>";
    echo "<tr class='tabPreciosTitles'>";
      echo "<td>Nom Activitat</td>
            <td>Nom Tipus Activitat</td>
            <td>Tipus Tarifa</td>
            <td>Temps/km</td>
            <td>Preu</td>";
    echo "</tr>";
for ($x=0;$x<count($savedArray[4]);$x++){
  echo "<tr>";
  echo "  <td>".$savedArray[0][$x]."</td>";
  echo "  <td>".$savedArray[1][$x]."</td>";
  echo "  <td>".$savedArray[2][$x]."</td>";
  echo "  <td>".$savedArray[3][$x]."</td>";
  echo "  <td>".$savedArray[4][$x]."</td>";
  echo "  <td><input type='submit' onclick='eliminar(".$savedArray[0][$x].",".$savedArray[1][$x].",".$savedArray[2][$x].",".$savedArray[3][$x].",".$savedArray[4][$x].")' class='carritoElim' value='elim'></td>";
  echo "</tr>";
}
