What are common issues when using "insert into" in PHP?

Common issues when using "insert into" in PHP include syntax errors in the SQL query, incorrect data types for the values being inserted, and not properly sanitizing user input to prevent SQL injection attacks. To solve these issues, make sure to double-check the syntax of your SQL query, ensure that the data types of the values match the column types in the database, and use prepared statements or parameterized queries to sanitize user input. 

// Example of using prepared statements to safely insert data into a database using "insert into"

// Assume $conn is a valid database connection

// Sample data to be inserted
$name = "John Doe";
$email = "johndoe@example.com";
$age = 30;

// Prepare the SQL query using prepared statements
$stmt = $conn->prepare("INSERT INTO users (name, email, age) VALUES (?, ?, ?)");
$stmt->bind_param("ssi", $name, $email, $age);

// Execute the query
$stmt->execute();

// Close the statement and connection
$stmt->close();
$conn->close();
