Also keep in mind that you can execute a w3coded statements stack prepared statement multiple times, if needed. w3coded statements stack You could also bind new parameters before w3coded statements stack re-executing your query.,Yes, it should work w3coded statements stack just fine.,You may be over-thinking things, w3coded statements stack because it's not different than any other w3coded statements stack prepared statement:,For a better and more w3coded statements stack complete explanation, please take a look at: w3coded statements stack w3coded statements stack (examples should get you up to speed).

So your above query would look like

// first, setup your DB-connection
$mysqli = new mysqli('', 'user', '********', 'database');

// Preparing the statement
$stmt = $mysqli->prepare('SELECT COUNT(*) FROM pj_galleries WHERE project = ?');

// binding the parameters
$stmt->bind_param('i', $pjInfo['pj_id']); // 'i' signals an integer

// Executing the query
if ( ! $stmt->execute()) {
    trigger_error('The query execution failed; MySQL said ('.$stmt->errno.') '.$stmt->error, E_USER_ERROR);

// fetching the results
$col1 = null;
$stmt->bind_result($col1); // you can bind multiple colums in one function call
while ($stmt->fetch()) { // for this query, there will only be one row, but it makes for a more complete example
    echo "counted {$col1} records\n";

$stmt->close(); // explicitly closing your statements is good practice

You may be over-thinking things, because it's not different than any other prepared statement:

$conn = new mysqli;
$sql = "SELECT COUNT(*) FROM pj_galleries WHERE project = ?";
$stmt = $conn->prepare($sql);
$stmt->bind_param('i', $pjInfo['pj_id']);
$row = $stmt->get_result()->fetch_row();
$galTotal = $row[0];
