How can syntax errors in MYSQL functions impact the functionality of PHP queries?

Syntax errors in MYSQL functions can cause PHP queries to fail because the incorrect syntax will not be understood by the database. To solve this issue, ensure that the MYSQL functions used in PHP queries are written correctly according to the MYSQL syntax rules.

$query = "SELECT * FROM users WHERE id = 1";
$result = mysqli_query($connection, $query);

if ($result) {
    // Process the query result
} else {
    echo "Error: " . mysqli_error($connection);
}
