How can PHP developers improve their understanding of basic SQL syntax and functions for data manipulation in MySQL databases?

PHP developers can improve their understanding of basic SQL syntax and functions for data manipulation in MySQL databases by practicing writing SQL queries, studying MySQL documentation, and experimenting with different SQL functions. They can also utilize PHP's built-in functions like mysqli_query() to execute SQL queries from their PHP scripts. 

// Example PHP code snippet to execute a simple SQL query in MySQL using mysqli_query()

$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// SQL query
$sql = "SELECT * FROM table_name";

// Execute query
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data of each row
    while($row = $result->fetch_assoc()) {
        echo "id: " . $row["id"]. " - Name: " . $row["name"]. "<br>";
    }
} else {
    echo "0 results";
}

// Close connection
$conn->close();
