Bug #78094 [NEW]: File Search Problem Excessive Time

From: dpfender44 at gmail dot com Operating system: Windows 10 PHP version: Next Major Version Package: *Directory/Filesystem functions Bug Type: Bug Bug description:File Search Problem Excessive Time Description: ------------ My function scan_dir() uses opendir(), chdir(), readdir(), is_dir(), closedir() to scan for files on the server. PHP version 7.4.0-dev does the same scan as version 7.3.6 but takes about 100 times longer. This is all done on the same server, but just switching between PHP versions on 5/31/19. The extra time seems to be spent doing readdir().
