Example 11-22 Using file_exists, touch, and unlink together

<?php
    $file_name="test.txt";

    if(file_exists($file_name))  {
     echo  ("$file_name  does  exist.<br>");
 }
 else  {
   echo  ("The  file  $file_name  does  not  exist.<br>");
   touch($file_name);
 }
 if(file_exists($file_name))  {
   echo  ("The  file  $file_name  does  exist.<br>");
   unlink($file_name);
 }
 else  {
   echo  ("The  file  $file_name  does  not  exist.<br>");
 }
 if(file_exists($file_name))  {
   echo  ("The  file  $file_name  does  exist.<br>");
 }
 else  {
   echo  ("The  file  $file_name  does  not  exist.<br>");
 }
?>

The output looks like Figure 11-18.
