How can one create custom word lists in the Aspell dictionary file format?

To create custom word lists in the Aspell dictionary file format, you can manually add your words to a text file with one word per line and then convert it to the Aspell dictionary format using the `aspell-import` utility provided by Aspell. This utility allows you to convert a plain text word list into the Aspell dictionary format.

// Example of creating a custom word list in Aspell dictionary format

// Define the custom word list
$wordList = "apple\nbanana\norange\n";

// Save the word list to a file
file_put_contents('custom_word_list.txt', $wordList);

// Convert the word list to Aspell dictionary format using aspell-import
exec('aspell-import dictionary custom_word_list.txt');
