What are some common pitfalls when using PHP to insert data into a MySQL table?

One common pitfall when using PHP to insert data into a MySQL table 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 SQL injection vulnerabilities. 

// Establish a database connection
$mysqli = new mysqli("localhost", "username", "password", "database");

// Prepare a SQL statement with placeholders
$stmt = $mysqli->prepare("INSERT INTO table_name (column1, column2) VALUES (?, ?)");

// Bind parameters to the placeholders
$stmt->bind_param("ss", $value1, $value2);

// Set the values of the parameters
$value1 = "some_value";
$value2 = "some_other_value";

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

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