What are some best practices for handling character count limitations in PHP when working with text content?

When working with character count limitations in PHP for text content, it is important to validate and enforce the limits to ensure that the input does not exceed the specified length. One approach is to use the `strlen()` function to check the length of the input and truncate it if it exceeds the limit. Additionally, you can provide feedback to the user if the input is too long. 

// Set the character limit
$characterLimit = 100;

// Get the input text
$inputText = $_POST['text'];

// Check if the input exceeds the character limit
if (strlen($inputText) > $characterLimit) {
    // Truncate the input to the character limit
    $inputText = substr($inputText, 0, $characterLimit);
    
    // Provide feedback to the user
    echo "Text exceeds character limit. Input truncated.";
}

// Use the sanitized input text
echo $inputText;
