Added PHP Direct System Shell Commands Collection

Added multiple PHP-based direct system shell commands using various PHP functions and shell types:

Basic System Shells:
PHP Direct System Shell (full bash reverse shell)
PHP Direct System Shell (Short) - simplified version
PHP Direct System Shell (One-Liner) - compact version using <?= syntax
Windows-Specific Shells:
PHP Direct PowerShell - using system() to spawn PowerShell reverse shell
PHP Direct CMD - using system() to spawn CMD via PowerShell
PHP Direct System Shell (netcat Windows) - using nc.exe
Unix/Linux Shells:
PHP Direct System Shell (netcat) - using traditional nc
PHP Direct System Shell (Python) - using Python socket
PHP Direct System Shell (Perl) - using Perl socket implementation
Alternative PHP Function Implementations:
PHP Direct System Shell (exec) - using exec() function
PHP Direct System Shell (passthru) - using passthru() function
PHP Direct System Shell (shell_exec) - using shell_exec() function
PHP Direct System Shell (popen) - using popen()/pclose() functions
Note: These shells rely on PHP's system execution functions being enabled and not restricted by disable_functions or safe mode. Success may vary depending on server configuration and security settings. Testing in your specific environment is recommended.

Key considerations:

Requires PHP system functions to be enabled
May be blocked by security configurations
Different methods provide fallback options
Windows vs Unix/Linux specific variations included
