Question

我有这个PHP代码将文件从一个目录复制到另一个目录并且它工作得很好但是，如何复制仅以字母“AUW”（减去引号）结尾的文件？请记住，该文件是无扩展名的，所以它真的以字母AUW结尾。

复制后，我也不希望从源文件夹中删除文件。

// 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);
}

Answer 1

您可以使用glob函数。

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

Answer 2

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);
}

Answer 3

您想使用glob功能。

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

Answer 4

使用substr() method获取文件名的最后三个字母。这将返回一个可用于逻辑比较的字符串。

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;
}

Answer 5

Google搜索太难了？我会给你一个提示 - 使用substr()查看最后3个字母是否为“AUW”

AH

PHP仅复制以字母AUW结尾的文件
