File exists php code.

Question

<?php

function data_info($data)
{
    if ($data) {
     while (!feof($data)) {
      $buffer = fgets($data);
      if (file_exists($buffer)) {
      $bufferArray[$buffer]['Exists'] = (file_exists($buffer));
      $bufferArray[$buffer]['Readable'] = (is_readable($buffer));
      $bufferArray[$buffer]['Writable'] = (is_writable($buffer));
      $bufferArray[$buffer]['Size'] = (filesize($buffer));
      } else {
       $bufferArray[$buffer]['Exists'] = "No";
      }
     }
     print_r($bufferArray);
    } else {
     echo "The file could not be opened";
    }
}

$data = fopen("D:/xampp/htdocs/Practice/ficheros.txt", "r");
data_info($data);

?>

If I have this: ficheros.txt: ExistingFile.txt ExistingFile2.txt ExistingFile3.txt... ... It works, but If I have at least 1 NON EXISTING FILE then It will take every file as a non existing one too.

What's wrong? I believe someting in the inner if condition.

Answer 1

Hmm, well that works in Linux (though I have to trim the filename $buffer first).

Answer 2

I mean, what is wrong with the entire code.

I just need to make an array with arrays in it, a good result would be:

    array
(
    'text.txt' => array
     (
     'exists' => true,
     'readable' => true,
     'writable' => true,
     'Size' => 64
     ),

    'document.doc' => array
     (
     'exists' => false
     ),

    'photo.jpg' => array
     (
    'exists' => true,
    'readable' => true,
    'writable' => false,
    'size' => 354915
     )
)

Answer 3

Yeah, It works for me too if I have in ficheros.txt

Existingfile.txt
AnotherExistingfile.txt

Or

FakeFile.txt
FakeFile2.txt

But If I combine both of them:

Fakefile.txt
Existingfile.txt

It won't work, the script in the last case takes both files as non existing ones.

Im not 100% why your wasn't but I played with it and this is working:

<?php

function data_info($data)
{
    if (!$data){return "The file could not be opened";}
    while (!feof($data))
     {
        $buffer = implode('',fgetcsv($data));//fgetcsv will only return an array with 1 item so impload it
     if(file_exists($buffer))
      {
      $bufferArray[$buffer]['Exists'] = (file_exists($buffer));
      $bufferArray[$buffer]['Readable'] = (is_readable($buffer));
      $bufferArray[$buffer]['Writable'] = (is_writable($buffer));
      $bufferArray[$buffer]['Size'] = (filesize($buffer));
      }
     else
      {
      $bufferArray[$buffer]['Exists'] = "No";
      }
     }
    print_r($bufferArray);
}

$data = fopen("c:/file.txt", "r");
data_info($data);

?>

The results from the file I used:

Array
(
    [c:/messageService.log] => Array
        (
            [Exists] => 1
            [Readable] => 1
            [Writable] => 1
            [Size] => 0
        )

    [c:/setup.log] => Array
        (
            [Exists] => 1
            [Readable] => 1
            [Writable] => 1
            [Size] => 169
        )

    [c:/fake1.txt] => Array
        (
            [Exists] => No
        )

    [c:/fake2.txt] => Array
        (
            [Exists] => No
        )

)

On second thought after looking at some of your comments, try it using exact paths instead of just the file name.

Answer 5

It seems that the \n messed up my strings, so I added trim as Athena said and worked. Thanks
