PHP Manager

GMSSH PHP Manager is a visual management tool for PHP runtime environments on Linux servers. It provides an intuitive graphical interface covering seven core modules: Console, Configuration, Disabled Functions, Performance, Logs, phpInfo, and Extensions, with multi-version PHP installation and switching support.

Core Features

Initialization

Smart Detection & Multi-Version Installation. When opening PHP Manager for the first time, the system automatically detects PHP installation status.

• Auto Detection: If PHP is not detected, the page prompts "PHP not installed, please select a version".
• Version Selection: Click the "Install" button or the top version dropdown to open the "PHP Version Management" panel.

Version Management

• Version List: Table showing all available PHP versions with version number, status, and actions.
• Multi-Version Coexistence: Supports installing multiple PHP versions simultaneously, switching via the top dropdown menu.
• Current Default: The installed version marked as "Current Default" is the primary running version.

Console

PHP-FPM Runtime Status Monitor. The Console module displays PHP-FPM status and performance metrics in a dashboard format.

• Runtime Status: Header shows current PHP version (e.g., PHP-8.3.25) and service status ("Running"), green indicates normal operation.
• Quick Actions: Three buttons in the top-right for one-click pause, stop, and restart.

Basic Runtime Info

Processes

Displayed with progress bars and numeric values:

Stability & Anomaly Monitoring

Configuration

Visual PHP Parameter Configuration. The Configuration module provides five tabs covering all dimensions of PHP runtime configuration.

Common Settings

Key PHP parameters in form layout:

• Save / Refresh: Click "Save" to write changes, "Refresh" to restore current values.

Limit Settings

• Scope: Both settings affect the Nginx configuration file.

Session Settings

• Storage Mode: Select session storage via dropdown (default files), with options for Redis, Memcache, etc.
• Performance Tip: For high-concurrency sites, Redis or Memcache can effectively improve PHP concurrency.
• Notes:
  • If website access becomes abnormal after changing session mode, switch back to the original mode.
  • Switching session mode will cause active user sessions to be lost; switch during low-traffic periods.

Config File

• Code Editor: Displays the full php.ini configuration with line numbers and syntax highlighting, supporting direct editing.
• Shortcuts: Ctrl+F for search, Ctrl+H for find & replace.
• Save: Click "Save" to write changes.
• Note: This is the main PHP config file. Do not modify if unfamiliar with configuration rules. OpenSSL/Curl/MySQL extensions are enabled by default.

FPM Config File

• Code Editor: Displays the PHP-FPM config file ([global] and [www] sections) with syntax highlighting.
• Shortcuts: Ctrl+F for search, Ctrl+H for find & replace.
• Note: This is the PHP-FPM config file. Do not modify if unfamiliar with configuration rules.

Disabled Functions

PHP Dangerous Function Security Control. Displays all disabled PHP functions in a card grid with search and management capabilities.

• Disabled Function List: Purple card grid showing all disabled function names (e.g., passthru, exec, system, shell_exec, popen, proc_open).
• Search: Top search box for quick function lookup.
• Add Function: "Add Function" button in the top-right to add new functions to the disabled list.
• Security Recommendation: Strongly recommended to disable dangerous functions like exec and system.

Performance

PHP-FPM Process Pool Tuning. Provides visual configuration of PHP-FPM core performance parameters with preset concurrency plans.

• Run Modes:
  • Static: Maintains a fixed number of child processes. Higher memory usage but better concurrency.
  • Dynamic: Reclaims processes based on max idle setting. Lower memory, recommended for small-memory servers.
  • On-Demand: Creates processes based on demand. Minimal memory but slightly lower concurrency.
• Notes:
  • Higher max_children = better concurrency, but do not exceed 5000.
  • Each PHP child process uses ~20MB memory; excessively high max_children may cause instability.
  • For external access, switch to TCP socket, set bind IP to 0.0.0.0, and configure IP whitelist and firewall.

Logs

PHP-FPM Runtime & Slow Log Management. Provides "Logs" and "Slow Logs" tabs.

Runtime Logs

• Displays PHP-FPM runtime logs including FPM startup info and connection ready status with precise timestamps.

Slow Logs

• Displays slow request records exceeding the threshold, helping identify performance bottlenecks.

phpInfo

Complete PHP Runtime Environment Info. Displays structured information about the current PHP version.

Basic Info

• View phpinfo: Top-right link to open the full phpinfo() page.

Extensions

One-Click PHP Extension Installation. Lists all available PHP extensions with one-click install support.

• Extension List:

• Notes:
  • Some extensions (e.g., Redis) only support single-version installation.
  • OPcache, XCache, APCu are mutually exclusive cache extensions — install only one.
  • Check installation logs if installation fails.
