Question

I want to create a function that replaces random words in a string. Here is what I thought of.

1. Given a string I would give a random index position within that string.
2. From that index I will replace the nearest word with a word that I want
3. Along with that I would store the word I just replace into some storage variable/database/file

Ex.

Random word seed: tree, cat, wolf, apple

String: The quick brown fox jumps over the lazy dog.

Possible Results:

1. The apple brown fox jumps cat the lazy dog.
2. The quick brown wolf tree over the lazy dog.
3. The quick tree fox tree over the lazy apple.

Answer 1

The clearest code would be had by

1. Splitting the string into an array words (e.g. with explode or preg_split for more heavy-duty logic)
2. Replacing randomly selected entries in the array as you see fit
3. Joining the words back into a string with (e.g. implode)
