What are the common mistakes to avoid when writing SQL queries in PHP, such as missing backticks or spaces in the query syntax?

Common mistakes to avoid when writing SQL queries in PHP include missing backticks around table or column names, forgetting to add spaces between keywords and identifiers, and not properly escaping user input to prevent SQL injection attacks. To solve these issues, always use backticks around table and column names, double-check the syntax for spaces between keywords and identifiers, and use prepared statements or parameterized queries to safely handle user input. 

// Example of a correct SQL query with backticks and proper spacing
$query = "SELECT `column1`, `column2` FROM `table_name` WHERE `column3` = :value";
$stmt = $pdo->prepare($query);
$stmt->execute(['value' => $input_value]);
