Making a temporary dir for unpacking a zipfile into

Question

I have a script that checks a zipfile containing a number of matching PDF+textfiles. I want to unpack, or somehow read the textfiles from the zipfile, and just pick out some

Another possibility is to use the temporal file as a kind of semaphore to guarantee the unicity of the directory name. Then, create a directory whose name is based on the file name.

define ('TMP_DIR', '/tmp'); // sys_get_temp_dir() PHP 5 >= 5.2.1
define ('TMP_DIR_PREFIX', 'tmpdir_');
define ('TMP_DIR_SUFFIX', '.d');

/* ************************************************************************** */

function createTmpDir() {
  $tmpFile = tempnam(TMP_DIR, TMP_DIR_PREFIX);
  $tmpDir = $tmpFile.TMP_DIR_SUFFIX;
  mkdir($tmpDir);
  return $tmpDir;
}

function rmTmpDir($tmpDir) {
  $offsetSuffix = -1 * strlen(TMP_DIR_SUFFIX);
  assert(strcmp(substr($tmpDir, $offsetSuffix), TMP_DIR_SUFFIX) === 0);
  $tmpFile = substr($tmpDir, 0, $offsetSuffix);

  // Removes non-empty directory
  $command = "rm -rf $tmpDir/";
  exec($command);
  // rmdir($tmpDir);

  unlink($tmpFile);
}
