How can PHP developers effectively debug and troubleshoot MySQL error messages like "Fehler 1064"?

When encountering a MySQL error like "Fehler 1064," it typically indicates a syntax error in the SQL query being executed. To troubleshoot this issue, PHP developers should carefully review the SQL query for any syntax errors, such as missing or misplaced punctuation marks. Additionally, using tools like phpMyAdmin or MySQL Workbench can help in visually identifying syntax errors in the query.

// Example SQL query with syntax error causing "Fehler 1064"
$sql = "SELECT * FROM users WHERE username = 'john' AND password = 'pass'"; // Missing closing quote for password value

// Corrected SQL query
$sql = "SELECT * FROM users WHERE username = 'john' AND password = 'pass'";
