What are some common debugging techniques for resolving SQL syntax errors in PHP scripts?

One common debugging technique for resolving SQL syntax errors in PHP scripts is to carefully review the SQL query being executed to identify any syntax errors such as missing quotes, incorrect table or column names, or improper use of SQL keywords. Another technique is to use PHP's error reporting functions such as mysqli_error() to get detailed error messages from the database server. Additionally, using prepared statements with parameterized queries can help prevent SQL injection attacks and reduce the likelihood of syntax errors. 

// Example of using mysqli_error() to get detailed error message
$query = "SELECT * FROM users WHERE username = '$username'";
$result = mysqli_query($conn, $query);

if (!$result) {
    die("Error: " . mysqli_error($conn));
}
