Loop code for each file in a directory [duplicate]

Answer 1

Use the glob function in a foreach loop to do whatever is an option. I also used the file_exists function in the example below to check if the directory exists before going any further.

$directory = 'my_directory/';
$extension = '.txt';

if ( file_exists($directory) ) {
   foreach ( glob($directory . '*' . $extension) as $file ) {
      echo $file;
   }
}
else {
   echo 'directory ' . $directory . ' doesn\'t exist!';
}

Answer 2

scandir:

$files = scandir('folder/');
foreach($files as $file) {
  //do your work here
}

or glob may be even better for your needs:

$files = glob('folder/*.{jpg,png,gif}', GLOB_BRACE);
foreach($files as $file) {
  //do your work here
}

Answer 3

Looks for the function glob():

<?php
$files = glob("dir/*.jpg");
foreach($files as $jpg){
    echo $jpg, "\n";
}
?>

Answer 4

Check out the DirectoryIterator class.

From one of the comments on that page:

// output all files and directories except for '.' and '..'
foreach (new DirectoryIterator('../moodle') as $fileInfo) {
    if($fileInfo->isDot()) continue;
    echo $fileInfo->getFilename() . "<br>\n";
}

The recursive version is RecursiveDirectoryIterator.

Answer 5

Try GLOB()

$dir = "/etc/php5/*";  

// Open a known directory, and proceed to read its contents  
foreach(glob($dir) as $file)  
{  
    echo "filename: $file : filetype: " . filetype($file) . "<br />";  
}
