Answer 1

<?php

if (isset($_POST['phone'])){
  $zapros1 = " and 'phone' IN ('".$_POST['phone']."')";
} else {$zapros1="";}

if (isset($_POST['dateadd'])){
  $zapros1 = " and 'dateadd' IN ('".$_POST['dateadd']."')";
} else {$zapros2="";}
        
if (isset($_POST['name'])){
  $zapros1 = " and 'name' IN ('".$_POST['name']."')";
} else {$zapros3="";}

if (isset($_POST['place'])){
  $zapros1 = " and 'place' IN ('".$_POST['place']."')";
} else {$zapros4="";}

$foolzapros="WHERE ".$zapros1.$zapros2.$zapros3;

etc. according to the text.
But in general, also look at the fact that you do not add $zapros4 to $foolzapros, do not use the $text variable and be sure to:

Answer 2

if ($phone){
    $zapros1 = " and `phone` IN ($phone)";

I wonder where phone could come from here? Where do you use these parameters of yours that you specified in the form? where $phone = $_POST['phone'] ?? null;
where is it all? php does not work as you wrote.

Answer 3

And they are the same.
In one case GiB, and in the other Gb.
