wampserver 404 error The requested URL was not found on this server - wampserver

Question

I installed wamp server and it works fine as the icon color is green and even the localhost works fine, but the problem happens when I add any PHP file inside www folder and try to access the file it gives me this message:
404 error The requested URL was not found on this server.
Any help will be appreciated.

Answer 1

How to run PHP project or files on wamp server at localhost?
Run wamp server
Create PHP project or file inside C://wamp/www/ directory.
Run your project or file means open URL in Browser ex: http://localhost/file_name.php or folder name
If a folder has an index.php file it will run by calling folder name in URL.

You should check the httpd-vhosts.conf file via /wamp64/bin/apache/apache2.4.41/conf/extra/httpd-vhosts.conf. the follwings; the port numbers here for example 83 cause it was my choice:
# Virtual Hosts
#
<VirtualHost *:83>
ServerName localhost
ServerAlias localhost
DocumentRoot "${INSTALL_DIR}/www"
<Directory "${INSTALL_DIR}/www/">
Options +Indexes +Includes +FollowSymLinks +MultiViews
AllowOverride All
Require local
</Directory>
</VirtualHost>
#
<VirtualHost *:83>
ServerName myProject
DocumentRoot "d:/wamp64/www/spip-projet-v"
<Directory "d:/wamp64/www/spip-projet-v/">
Options +Indexes +Includes +FollowSymLinks +MultiViews
AllowOverride All
Require local
</Directory>
</VirtualHost>
