The LuaSandbox class

(PECL luasandbox >= 1.0.0)

Introduction

The LuaSandbox class creates a Lua environment and allows for execution of Lua code.

class LuaSandbox {

/* Constants */

const int SAMPLES = 0;

const int SECONDS = 1;

const int PERCENT = 2;

/* Methods */

public callFunction(string $name, mixed ...$args): array|bool

public enableProfiler(float $period = 0.02): bool

public getCPUUsage(): float

public getProfilerFunctionReport(int $units = LuaSandbox::SECONDS): array

public static getVersionInfo(): array

public loadBinary(string $code, string $chunkName = ''): LuaSandboxFunction

public loadString(string $code, string $chunkName = ''): LuaSandboxFunction

public registerLibrary(string $libname, array $functions): void

public setCPULimit(float|bool $limit): void

public setMemoryLimit(int $limit): void

}

LuaSandbox::SAMPLES: Used with LuaSandbox::getProfilerFunctionReport() to return timings in samples.
LuaSandbox::SECONDS: Used with LuaSandbox::getProfilerFunctionReport() to return timings in seconds.
LuaSandbox::PERCENT: Used with LuaSandbox::getProfilerFunctionReport() to return timings in percentages of the total.
