You probably want to create a map, which allows you to associate keys and values - you can use your strings as the keys and their counts as the values. See the documentation about maps. Obviously you'll need to get a list of all the strings in your file first. As far as actually reading from a file goes, you'll probably want to use fopen() and fread() to do that. Again see the PHP documentation for information on these functions.

Do they give homework assignment in PHP nowadays?

Anyway, you COULD study array use in PHP. For each word you read you look up if the index exists. If so, increase the value of the element with that index, if not, create one and set the value to 1.

Notes on fread etc by Nylex are valid of course.
