How important is it for PHP developers to have a basic understanding of SQL and database management, even if they are using alternative methods for data storage in their projects?

It is crucial for PHP developers to have a basic understanding of SQL and database management, even if they are using alternative methods for data storage in their projects. This knowledge allows developers to efficiently interact with databases, write optimized queries, and handle data securely. Additionally, many PHP frameworks and libraries rely on SQL for data manipulation, so having a solid understanding of SQL can greatly enhance a developer's capabilities. 

// Example code snippet demonstrating the use of SQL queries in PHP
$conn = new mysqli($servername, $username, $password, $dbname);

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

$sql = "SELECT id, name, email FROM users";
$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"]. " - Email: " . $row["email"]. "<br>";
    }
} else {
    echo "0 results";
}

$conn->close();
