Question: I have an entity `Customer` with an simple\_array field `processNumbers`. So in the DB its saved as an comma-separated list for example: `45645,78787,1111`.
Now I want to find an entry with a specific number `processNumber = 1111`.
I want to do it with the query builder, but I only know the direction when I have an array and I search if a DB entry is in it. This direction doesn't work, it says that there is no entry, but it is:

```
$customer = $queryBuilder
            ->select('customer')
            ->from(Customer::class,'customer')
            ->where(":processNumber IN (customer.processNumbers)")
            ->setParameter('processNumber', $processNumber)
            ->getQuery()->getResult();

```

Answer: 
The problem is the `?>;`, remove the `;` there because also belongs to the output that is send to the client.

When I used php it was a good practice to omit the last `?>` in general and only add it if there is really data that has to be displayed. That reduces the probability that accidentally add unwanted output.
If i am not mistaken you have not added dataType in your ajax call.

**dataType** informs which type of data to be expected from response, which in your case json.

```
var driverList = [];

$.ajax({
    url: './php/GetDriverList.php',
    type: 'post',
    dataType : 'json',
    success: function(response){
        console.log(response);
        var tempList = JSON.parse(response);
        for(var i = 0; i < tempList.length; i++){
            driverList.push(tempList[i]);
        }
        buildTable(driverList);
    }
});

```
