Delete particular word from string

In PHP, you can use the str_replace function to delete a particular word from a string. The function takes three arguments: the word or phrase to be replaced, the replacement word or phrase, and the string.

For example, to delete the word "apple" from the string "I have an apple", you would use the following code:
