What are potential pitfalls when storing JSON strings in a PHP database?

One potential pitfall when storing JSON strings in a PHP database is that the JSON data may not be properly escaped before inserting into the database, leading to SQL injection vulnerabilities. To solve this issue, use prepared statements with parameterized queries to securely insert JSON data into the database. 

// Assume $jsonString contains the JSON data to be stored in the database

// Establish a database connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Prepare a SQL statement with a parameterized query
$stmt = $conn->prepare("INSERT INTO table_name (json_column) VALUES (?)");
$stmt->bind_param("s", $jsonString);

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

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