To check if a string contains a phrase, you can use the `includes()` method in JavaScript, the `in` operator or `find()` method in Python, or similar methods specific to the programming language you're using. For instance, in Python, simply write `'phrase' in string` to return `True` if the string contains the phrase, and `False` otherwise. Always ensure the string and phrase are properly formatted for accurate detection.
