What are the potential benefits of implementing a custom function to handle MySQL queries in PHP scripts?
When handling MySQL queries in PHP scripts, implementing a custom function can provide several benefits such as improved code readability, reusability, and security. By encapsulating the query logic within a function, it becomes easier to maintain and modify queries throughout the codebase. Additionally, custom functions can help prevent SQL injection attacks by properly escaping user input before executing queries.
// Custom function to handle MySQL queries in PHP scripts
function executeQuery($query) {
$connection = mysqli_connect("localhost", "username", "password", "database");
if (!$connection) {
die("Connection failed: " . mysqli_connect_error());
}
$result = mysqli_query($connection, $query);
mysqli_close($connection);
return $result;
}
// Example usage
$query = "SELECT * FROM users WHERE id = 1";
$result = executeQuery($query);
// Process the query result
if (mysqli_num_rows($result) > 0) {
while ($row = mysqli_fetch_assoc($result)) {
echo "Name: " . $row["name"] . "<br>";
}
} else {
echo "No results found.";
}
