What are common SQL syntax errors that PHP developers encounter when working with MySQL databases?

One common SQL syntax error that PHP developers encounter when working with MySQL databases is forgetting to properly escape strings in their queries. This can lead to SQL injection vulnerabilities and syntax errors. To solve this issue, developers should use parameterized queries or escape user input before constructing SQL queries. Example PHP code snippet using parameterized queries: 

// Connect to the database
$pdo = new PDO('mysql:host=localhost;dbname=my_database', 'username', 'password');

// Prepare a SQL statement with a parameter
$stmt = $pdo->prepare('SELECT * FROM users WHERE username = :username');

// Bind the parameter value
$stmt->bindParam(':username', $username);

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

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