• Modify conf/httpd.conf, remove the indexes for the directory access

<Directory "${SRVROOT}/htdocs">
    Options FollowSymLinks
    AllowOverride None
    Require all granted
</Directory>

• Configure Apache to recognize index.php

<IfModule dir_module>
    DirectoryIndex index.php index.html
</IfModule>

• Restart Apache using httpd.exe -k restart
• Visit http://localhost:7070/tp5/public/ and now we see welcome page from think-php
