What are the challenges and problems that may arise when handling data for different output contexts, such as HTML, PDF, or databases, in PHP?

One challenge that may arise when handling data for different output contexts in PHP is ensuring that the data is properly formatted and structured for each specific output format. To solve this issue, you can use conditional statements to check the output context and format the data accordingly. 

// Example of handling data for different output contexts

// Data to be output
$data = [
    'name' => 'John Doe',
    'age' => 30,
    'email' => 'johndoe@example.com'
];

// Check the output context
$outputContext = 'html';

// Format the data based on the output context
if ($outputContext === 'html') {
    // Output data in HTML format
    echo '<p>Name: ' . $data['name'] . '</p>';
    echo '<p>Age: ' . $data['age'] . '</p>';
    echo '<p>Email: ' . $data['email'] . '</p>';
} elseif ($outputContext === 'pdf') {
    // Output data in PDF format
    // Code to generate PDF output
} elseif ($outputContext === 'database') {
    // Store data in a database
    // Code to insert data into database
}
