How can syntax errors in SQL queries be identified and resolved when using PHP?

Syntax errors in SQL queries can be identified by looking at the error message returned by the database when executing the query. Common syntax errors include missing quotes around strings, incorrect table or column names, and missing commas between values. To resolve syntax errors, carefully review the query for any mistakes and make necessary corrections.

// Example SQL query with syntax error
$query = "SELECT * FROM users WHERE name = $username";

// Corrected SQL query with quotes around $username
$query = "SELECT * FROM users WHERE name = '$username'";
