What are common syntax errors to look out for when using PHP for database operations like inserting data?

Common syntax errors to look out for when using PHP for database operations like inserting data include missing semicolons at the end of SQL statements, incorrect quoting of values, and using reserved words as column names without backticks. To solve these issues, always double-check your SQL statements for proper syntax, ensure that values are properly quoted, and use backticks for column names that are reserved words. 

// Example code snippet fixing common syntax errors when inserting data into a database using PHP

// Define variables for database connection
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database_name";

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

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

// Example SQL insert statement with proper syntax and quoting of values
$sql = "INSERT INTO table_name (column1, column2) VALUES ('value1', 'value2')";

// Check if the query was successful
if ($conn->query($sql) === TRUE) {
    echo "New record created successfully";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

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