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:

<?php

$string = "I have an apple";
$string = str_replace("apple", "", $string);
echo $string; // Output: "I have an "

You can also use preg_replace function with regular expression to match and delete a particular word from a string.

<?php

$string = "I have an apple";
$string = preg_replace('/\bapple\b/', '', $string);
echo $string; // Output: "I have an "

Note that this will only remove the exact word "apple" and not any word that contains the letters "apple" such as "applesauce" or "pineapple".
