What strategies can be employed to troubleshoot issues where specific parts of a SQL query are being ignored in PHP code?

When specific parts of a SQL query are being ignored in PHP code, it could be due to syntax errors or incorrect usage of variables. To troubleshoot this issue, check for any typos or missing quotes in the SQL query string, ensure that variables are properly concatenated into the query, and use prepared statements to prevent SQL injection attacks.

// Example code snippet to troubleshoot SQL query being ignored
$sql = "SELECT * FROM table WHERE column = :value";
$stmt = $pdo->prepare($sql);
$stmt->bindParam(':value', $variable);
$stmt->execute();
$results = $stmt->fetchAll();
