PHP copy only files ending with letters AUW

本文关键字：AUW 结尾文件复制 PHP | 更新日期: 2024-01-05

我有这个PHP代码可以将文件从一个目录复制到另一个目录，它工作得很好，但是，我如何只复制以字母"AUW"（减去引号）结尾的文件？请记住，该文件是无扩展名的，因此它实际上以字母AUW结尾。

此外，在复制后，我不希望从源文件夹中删除这些文件。

// Get array of all source files
$files = scandir("sourcefolder");
// Identify directories
$source = "sourcefolder/";
$destination = "destinationfolder/";
// Cycle through all source files
foreach ($files as $file) {
  if (in_array($file, array(".",".."))) continue;
  // If we copied this successfully, mark it for deletion
  if (copy($source.$file, $destination.$file)) {
    $delete[] = $source.$file;
  }
}
// Delete all successfully-copied files
foreach ($delete as $file) {
  unlink($file);
}

foreach ($files as $file) {
  if (in_array($file, array(".",".."))) continue;
  if (!endsWith($file, "AUW")) continue;
  // If we copied this successfully, mark it for deletion
  if (copy($source.$file, $destination.$file)) {
    // comment the following line will not add the files to the delete array and they will
    // not be deleted
    // $delete[] = $source.$file;
  }
}
// comment the followig line of code since we dont want to delete
// anything
// foreach ($delete as $file) {
//   unlink($file);
// }
function endsWith($haystack, $needle)
{
    $length = strlen($needle);
    if ($length == 0) return true;
    return (substr($haystack, -$length) === $needle);
}

您可以使用函数glob。

foreach (glob("*AUW") as $filename) {
   // do the work...
}

您想要使用glob函数。

foreach( glob( "*.AUW" ) as $filename )
{
      echo $filename;
}

使用substr（）方法获取文件名的最后三个字母。这将返回一个可以在逻辑比较中使用的字符串。

if( substr( $file, -3 ) == 'AUW' )
{
  // Process files according to your exception.
}
else
{
  // If we copied this successfully, mark it for deletion
  if (copy($source.$file, $destination.$file)) {
    $delete[] = $source.$file;
}

谷歌搜索太难了吗？我会给你一个提示-用substr()看看最后3个字母是否是"AUW"
