What are the potential pitfalls of variable passing in PHP when trying to edit table data?

When passing variables in PHP to edit table data, one potential pitfall is not properly sanitizing user input, which can lead to SQL injection attacks. To solve this issue, always use prepared statements with parameterized queries to prevent malicious code from being executed. 

// Connect to database
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");

// Prepare SQL statement with placeholders
$stmt = $pdo->prepare("UPDATE mytable SET column1 = :value1 WHERE id = :id");

// Bind parameters and execute query
$stmt->bindParam(':value1', $value1);
$stmt->bindParam(':id', $id);
$stmt->execute();
