how to move to the top an array element

I have selected rows from a table
target row is a row having id equal to $_GET['id']
I want to move it at the top of rows

$sq = "select * from video order by ind asc";
$st = $db->prepare($sq);
$st->execute();
$rows = $st->fetchAll();

if(isset($_GET['id'])){
    foreach($rows as $row){
        if($row['id'] == $_GET['id']){
            unset($rows[$row]);  // error line
            $rows = $row + $rows;
        }
    }
}

error - Illegal offset type in unset...
also - is there a shorter way to do this, i.e. to avoid loop
something like:

$rows[having id equal to $_GET['id']] -> move-to-top

For this line,

unset($rows[$row]);  // error line

you need to unset the key in $rows and not $row itself which is a value in the foreach loop.

So, for unsetting it would look like:

<?php

foreach($rows as $key => $row){
    if($row['id'] == $_GET['id']){
        unset($rows[$key]); 
        // code line to move to the top 
        break;
    }
}

Don't use $rows = $row + $rows; kind of syntax as it makes it difficult to read during code reviews.

For a shorter syntax, you can use array_filter to filter out the row and then perform a swap taking the help of symmetric-array-destructuring.

Snippet:

<?php

$row = array_filter($rows, fn($arr) => $arr['id'] == $testID);
[$rows[array_keys($row)[0]], $rows[0]] = [$rows[0], $rows[array_keys($row)[0]]];
