"This code example shows a function that searches for all products that match a keyword by making an API request and parsing the JSON response. The function is called with a keyword parameter, and the results are displayed by looping through the array and echoing the name and price of each product. Package/library: cURL, JSON extension In general, the package/library used for a search function in PHP can vary depending on the type of data source being searched (e.g. database, API, file), and the specific requirements of the search operation. The examples above illustrate the use of different packages and libraries for two distinct types of data sources.
