What potential challenges or limitations may arise when using PHP for spell checking?

One potential challenge when using PHP for spell checking is the lack of built-in spell checking functionality. To address this limitation, developers can utilize external libraries or APIs that offer spell checking capabilities. By integrating these resources into their PHP code, developers can enhance the spell checking functionality of their applications.

// Example of using an external spell checking library in PHP

// Include the library
require_once('path/to/spell-checking-library.php');

// Initialize the spell checker
$spellChecker = new SpellChecker();

// Check the spelling of a word
$misspelledWord = "wrogn";
$correctedWord = $spellChecker->checkSpelling($misspelledWord);

echo "Misspelled word: " . $misspelledWord . "<br>";
echo "Corrected word: " . $correctedWord . "<br>";
