In what situations would it be advisable to use var_dump() in PHP to troubleshoot code errors related to database interactions?
When troubleshooting code errors related to database interactions in PHP, it would be advisable to use var_dump() to inspect the data being retrieved from the database. This can help identify any discrepancies between the expected data and the actual data being returned, allowing for more targeted debugging.
// Example code snippet using var_dump() for troubleshooting database interactions
$query = "SELECT * FROM users";
$result = mysqli_query($connection, $query);
if ($result) {
while ($row = mysqli_fetch_assoc($result)) {
var_dump($row); // Use var_dump() to inspect the data retrieved from the database
}
} else {
echo "Error: " . mysqli_error($connection);
}
