What are common syntax errors in PHP that can lead to SQL syntax errors like the one mentioned in the forum thread?

Common syntax errors in PHP that can lead to SQL syntax errors include missing semicolons at the end of SQL statements, improperly escaping special characters in SQL queries, and using incorrect quotation marks around string values in SQL queries. To solve these issues, always double-check the syntax of your SQL queries and ensure that all special characters are properly escaped.

// Incorrect SQL query with missing semicolon
$sql = "SELECT * FROM users WHERE id = 1"
$result = mysqli_query($conn, $sql); // Missing semicolon here

// Corrected SQL query with semicolon
$sql = "SELECT * FROM users WHERE id = 1;";
$result = mysqli_query($conn, $sql);
