How can you ensure that search results in PHP only display exact matches to the input in a text field?

To ensure that search results in PHP only display exact matches to the input in a text field, you can use the PHP function `strcmp()` to compare the search input with the items in your dataset. This function compares two strings and returns 0 if they are equal. By checking for a return value of 0, you can filter out any results that do not exactly match the search input. 

<?php

// Sample dataset
$items = ["apple", "banana", "orange", "grape"];

// Search input
$searchInput = "banana";

// Loop through the dataset and display exact matches
foreach ($items as $item) {
    if (strcmp($searchInput, $item) === 0) {
        echo $item . "<br>";
    }
}

?>
