What is the purpose of the search function in the PHP code provided?

The purpose of the search function in the PHP code provided is to search for a specific value within an array and return its index if found. To fix the issue, we need to modify the search function to return the index of the element if it is found, and return -1 if the element is not found. 

function search($array, $value) {
    foreach($array as $key => $element) {
        if($element == $value) {
            return $key; // Return index if value is found
        }
    }
    return -1; // Return -1 if value is not found
}

// Example usage
$array = [1, 2, 3, 4, 5];
$value = 3;
$result = search($array, $value);
if($result != -1) {
    echo "Value found at index: " . $result;
} else {
    echo "Value not found in array";
}
