PHP is_file () not working properly

Question

I want to check the files in the directory, and I use scandir()and is_file()to test. In this simple code, is_file()return falsefor me. but in the directory I have 3 files.

$files = scandir('uploads/slideShow');
$sfiles = array();
foreach($files as $file) {
  if( is_file($file) ) {
    $sfiles[] = $file;
    // echo $file;
  }
}

for scandir()with variable $file:

Array
(
  [0] => .
  [1] => ..
  [2] => 6696_930.jpg
  [3] => 9_8912141076_L600.jpg
  [4] => untitled file.txt
)

result for $sfiles:

Array
(
)

Answer 1

The problem is that it scandironly returns the file name, so your code looks for untitled file.txtet al in the current directory, not the scanned one.

This contrasts with glob("uploads/slideShow/*")which will return the full path to the files you are looking at. If you use this globwith is_file, it should work fine.

, , ... :

$files = scandir('uploads/slideShow');
// ...
foreach($files as $file) {
    if ( is_file('uploads/slideShow/'. $file) ) {
        // file found!
    }
}
