What is the correct syntax for a SQL query in PHP to avoid errors like "You have an error in your SQL syntax"?

When writing SQL queries in PHP, it is important to properly format the query string to avoid errors like "You have an error in your SQL syntax". One common mistake is not properly escaping variables or using double quotes instead of single quotes for string values. To solve this issue, always use prepared statements with placeholders for variables and ensure that string values are enclosed in single quotes. 

// Example of a correct SQL query syntax in PHP using prepared statements

// Establish a database connection
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");

// Prepare a SQL statement with a placeholder for a variable
$stmt = $pdo->prepare("SELECT * FROM my_table WHERE column_name = :value");

// Bind the variable to the placeholder
$value = "example";
$stmt->bindParam(':value', $value);

// Execute the query
$stmt->execute();

// Fetch the results
$results = $stmt->fetchAll(PDO::FETCH_ASSOC);
