PHP Code Display Issue

### For Apache:

1. **Ensure PHP is Installed:**
Make sure PHP and the necessary PHP modules are installed. You can install PHP using the following command:

sudo apt update
   sudo apt install php libapache2-mod-php

2. **Check Apache Configuration:**
Ensure that your `site.conf` file has the following lines to enable PHP processing:

<IfModule mod_php7.c>
       AddType application/x-httpd-php .php
   </IfModule>
   <IfModule mod_php.c>
       AddType application/x-httpd-php .php
   </IfModule>

3. **Restart Apache:**
After making changes to the configuration, restart Apache:

sudo systemctl restart apache2

4. **Check PHP Files:**
Make sure that your PHP files have the correct file extension (e.g., `.php`).

### For Nginx:

1. **Ensure PHP is Installed:**
Similar to Apache, ensure PHP is installed along with the PHP-FPM package:

sudo apt update
   sudo apt install php php-fpm

2. **Check Nginx Configuration:**
In your `site.conf`, make sure you have the following configuration:

server {
       listen 80;
       server_name your_domain_or_ip;

       root /var/www/your_site;
       index index.php index.html index.htm;

       location / {
           try_files $uri $uri/ =404;
       }

       location ~ .php$ {
           include snippets/fastcgi-php.conf;
           fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;  # Adjust PHP version as needed
           fastcgi_index index.php;
           fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
           include fastcgi_params;
       }
   }

3. **Restart Nginx:**
Restart Nginx after making the configuration changes:

sudo systemctl restart nginx

### Verify PHP is Working

To test if PHP is working, you can create a simple `info.php` file in your web root directory:

<?php
phpinfo();

Access it in your browser by navigating to `http://your_domain_or_ip/info.php`. If configured correctly, you should see the PHP information page.

### Summary
Make sure that your server is configured to handle PHP files properly, and don't forget to restart the web server after making changes to the configuration files. If you encounter any issues, check the server error logs for more details on what might be wrong.

### 1. Verify PHP Installation

First, ensure that PHP and the necessary modules are installed. You can check the installed version of PHP by running:

php -v

If PHP 8.3 is not installed, you can install it with:

sudo apt update
sudo apt install php8.3 libapache2-mod-php8.3

### 2. Check Apache Configuration

Make sure that your Apache configuration file (`site.conf` or the equivalent for your site) is correctly set up to handle PHP files. Open your configuration file and ensure it includes these lines:

<IfModule mod_php8.c>
    AddType application/x-httpd-php .php
</IfModule>

<Directory /var/www/your_site>
    AllowOverride All
</Directory>

<FilesMatch .php$>
    SetHandler application/x-httpd-php
</FilesMatch>

### 3. Enable Required Apache Modules

Make sure the necessary Apache modules for PHP are enabled. Run the following commands:

sudo a2enmod php8.3
sudo a2enmod rewrite

After enabling the modules, restart Apache:

sudo systemctl restart apache2

### 4. Check PHP File Permissions

Ensure that your PHP files have the correct permissions. The web server needs permission to read the files. You can set appropriate permissions with:

sudo chown -R www-data:www-data /var/www/your_site
sudo find /var/www/your_site -type d -exec chmod 755 {} ;
sudo find /var/www/your_site -type f -exec chmod 644 {} ;

### 5. Create a Test PHP File

To verify that PHP is working, create a test file called `info.php` in your web root directory:

<?php
phpinfo();

Access this file via your web browser at `http://your_domain_or_ip/info.php`. If PHP is configured correctly, you should see the PHP information page.

### 6. Check Apache Error Logs

If you are still experiencing issues, check the Apache error logs for any messages that might indicate what is wrong:

sudo tail -f /var/log/apache2/error.log

### Summary

By following these steps, you should be able to configure your Apache server to correctly execute PHP files. Make sure to restart Apache after making any changes and check for errors in the logs if you encounter issues. If you need further assistance, feel free to ask!

### Step 1: Download Adminer

First, you need to download the Adminer PHP file. You can do this directly in the terminal using `wget` or by downloading it through a web browser.

**Using wget:**

cd /var/www/html/adminer  # Change to the desired directory
sudo mkdir adminer
cd adminer
sudo wget "https://www.adminer.org/latest.php" -O index.php

### Step 2: Create `adminer.conf`

Next, create the `adminer.conf` file in the `/etc/apache2/sites-available` directory. This file will contain the configuration for Adminer.

sudo nano /etc/apache2/sites-available/adminer.conf

Add the following configuration to `adminer.conf`:

<VirtualHost *:80>
    ServerName adminer.your_domain_or_ip  # Change to your domain or IP

    DocumentRoot /var/www/html/adminer  # Path to your adminer directory
    <Directory /var/www/html/adminer>
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>

    ErrorLog ${APACHE_LOG_DIR}/adminer_error.log
    CustomLog ${APACHE_LOG_DIR}/adminer_access.log combined
</VirtualHost>

### Step 3: Enable the Adminer Site Configuration

Enable the new Adminer configuration and reload Apache:

sudo a2ensite adminer.conf
sudo systemctl reload apache2

### Step 4: Configure Your Domain or Host

If you are using a domain, make sure it points to your server’s IP address. You might need to add an entry in your local `hosts` file if you are testing this locally.

For example, if you set `ServerName adminer.your_domain_or_ip`, add the following line to your local `/etc/hosts` file (on Linux/Mac) or `C:WindowsSystem32driversetchosts` file (on Windows):

your_server_ip adminer.your_domain_or_ip

### Step 5: Access Adminer

Now, you can access Adminer by navigating to `http://adminer.your_domain_or_ip` in your web browser.

### Step 6: Secure Adminer (Optional)

To enhance security, consider restricting access to Adminer. You can do this by allowing access only from specific IP addresses or by setting up basic authentication. Here’s a quick way to enable basic authentication:

1. **Install `apache2-utils` (if not already installed):**

sudo apt install apache2-utils

2. **Create a password file:**

sudo htpasswd -c /etc/phpmyadmin/.htpasswd your_username

3. **Update `adminer.conf`:**

Add the following lines inside the “ block in `adminer.conf`:

AuthType Basic
   AuthName "Restricted Access"
   AuthUserFile /etc/phpmyadmin/.htpasswd
   Require valid-user

4. **Reload Apache:**

sudo systemctl reload apache2

### Conclusion

You should now have Adminer installed and configured on your Apache server. Make sure to secure it properly and only allow trusted users to access it. If you have any further questions or need assistance, feel free to ask!
