PHP Code:

C_DLLEXPORT int Meta_Attach(PLUG_LOADTIME, 
        META_FUNCTIONS *pFunctionTable, meta_globals_t *pMGlobals, 
        gamedll_funcs_t *pGamedllFuncs) 
{ 

    gpMetaGlobals=pMGlobals;
    memcpy(pFunctionTable, &gMetaFunctionTable, sizeof(META_FUNCTIONS));
    gpGamedllFuncs=pGamedllFuncs;

    SERVER_COMMAND("mycmd");
    SERVER_EXECUTE();
...
} 


Nothing seems to happen after using SERVER_COMMAND or SERVER_EXECUTE.

I see that here is also a function CLIENT_COMMAND(edict_t *pEdict, const char *szFmt,...) but I don't know how to get the pointer to the client entity that loaded the plugin.
