无法使用file_exists查找文件

Question

I am trying to look for a file called test.txt within the folder called .test.

<?php 
 $path = '/localhost/joshcms/.test/test.txt';
 $fileexists = file_exists($path);
 if ($fileexists == '1') {
  $result = 'true';
 } else {
   $result = 'false';
 }
?>

Please excuse the horrible formatting, I am creating this PHP within Jade.

I, first of all, had the $path variable set to .test/test.txt so when it searched for the file, it looked in: localhost/joshcms/.test/test.txt because it was a relative path; because that never worked, I then changed the code to look the way it is above and yet, it still does not work. I then tried with a file that was in the same folder and that worked fine.

I'm not too sure if this error is occurring due to me trying to find something in a hidden folder or if it's just the function doesn't work unless the file is in the same directory as the PHP script/file itself.

file_exists() returns bool(true|false), so checking the response against a string '1' like so if ($fileexists == '1') will not pass.

The following will work:

$path = '/localhost/joshcms/.test/test.txt';
if ( file_exists($path) ) { // returns bool(true|false) response
    $result = 'true'; // if file exists, this condition will satisfy as the file does exist bool(true)
} else {
   $result = 'false'; // if the file at $path does not exist, this will satisfy; bool(false)
}

Aside: $result will now, per your code, hold a string value of true/false. If you want $result to hold a boolean value of true/false, remove the single-quotes, ie. $result = true; and $result = false;, respectively.
