PHP单数和复数文本编辑

I have a sentence like this:

<h5>There are <?php echo $total_results_count; ?> results waiting for you!</h5>

How could I modify this to say:

There is 1 result waiting for you!

if there is only 1 result.

<h5><?php
if ($total_results_count > 1) {
  echo 'There are ' . $total_results_count . ' results';
}
else {
  echo 'There is ' . $total_results_count . ' result';
} ?> waiting for you!</h5>

Get results into a variable. Then,

if($count == 1){
  str_replace("are results","is 1 result ","There are results waiting for you!");
}

As easy as:<h5>There <?php if($total_results_count>1) echo "are"; else echo "is" $total_results_count. " result"; if($total_results_count>1) echo "s";?> waiting for you!</h5>

<?php
if( $total_results_count > 1 ) {
    echo '<h5>There are '.$total_results_count.' results waiting for you!</h5>';
} else {
    echo '<h5>There is 1 result waiting for you!</h5>';
}
