Hello! You can use file_get_contents to grab all the data from a file, str_replace to delete certain words, then file_put_contents to overwrite the file data. Here is an example:

<?php
/**
 * This is an example PHP script to delete all of the
 * vowels from a text file.
 */

//create a variable to point to the filename
$file = 'test_file.txt';

//move the contents of the file into a variable
$current = file_get_contents($file);

//create a variable to hold everything you want to search for in the contents
//in your case, this could be an array of adult words
$vowels = array("a", "e", "i", "o", "u", "y", "A", "E", "I", "O", "U", "Y");

//replace each of the searchable items above with a ""
//this esentially deletes those items in the array
$onlyconsonants = str_replace($vowels, "", $current);

//replace the contents of the file with the result of
//the string replace (str_replace) command above
file_put_contents($file, $onlyconsonants);

?>
