Some PHP code snippets to manipulate directories and files.

php_list_directory.php

<?php
$source = "/path/to/your/file/";
$files = scandir("$source");

foreach($files as $file) {
  // inside this loop, we strip the information from the CSV file
  $arrLines = file($source . $file);
  
  foreach($arrLines as $lines) {
    // display each element
    $eemport = explode(',', $lines);
    // foreach ($eemport as $value) {
    // 	echo $value . "\t";
    // }
    
    $manuel = strtolower($eemport[4]);
    $ma = substr($manuel, 0, 2);
  }
}

# delete the file
unlink($source.$file)

/**
 * Use this loop if you want to ignore the '.' and '..' in the diretory
 */
foreach ($files as $file) {
  if($file != '.' && $file != '..') {
    $file_info = pathinfo($file);
    $file_ext = $file_info['extension'];
    if($file_ext == 'jpg') {
      $new_name = 'owsm_rakuunz.' . $file_ext;
      rename($source.$file, $source.$new_name);
      echo $new_name . ' modified on ' . date('Y-m-d H:i:s', filemtime($source.$new_name)) . '<br>';
      // filemtime function is used to display the time the file last modified
    } else {
      echo $file . ' modified on ' . date('Y-m-d H:i:s', filemtime($source.$file)) . '<br>';
    }
  }
}

// Another way to skip files and dots is to declare an array of unwanted files.
$ignored = array('.', '..', '.svn', '.htaccess');

// then skip if with this:
if(in_array($file, $ignored)) continue;
?>
