Equivalent relationship between PHP and ASP objects [zz]

Http://www.ttud.com/info/1661.htm

1) write HTML ASP: Response. Write (STR) PHP: Print $ STR; Echo $ STR; Print_r $ debug_str; 2) form, Cookie and querystring variable ASP: You can use request object. PHP: these variables are automatically provided as a global variable, IF configured in the PHP. ini file as follows: Variables_order = "egpcs" Register_globals = on For security, I will not allow register_globals (set it to Off). Then the variable is only used in the array: $ Http_post_vars, $ http_cookie_vars and $ http_get_vars. 3) Redirecting to another location ASP: Response. Redirect (URL) PHP: Header ("Location: $ URL "); 4) Cookie Processing ASP: Response. Cookies (cookiename) = newval Avar = request. Cookies (cookiename) PHP: setcookie ($ cookiename, $ newval ); $ Avar = $ http_cookie_vars [$ cookiename]; 5) Application variable ASP: Application (appvarname) PHP: No. It can be simulated using a database. 6) Session Variables ASP: Session (sessionname) = newval Avar = SESSION (sessionname) PHP: In PhP4 or later versions, we determine that the variable is used as a session in Session_register ($ sessionname). Then, we call session_start () Resume the session variable value on the. PHP page. For example: Session_register ('avar '); $ Avar = 99; Session_start (); Print $ Avar; 7) form variable ASP: request. Form ("formvar ") Request. querystring ("getvar ") PHP: $ http_post_vars ["formvar"]; $ Http_get_vars ["getvar"]; The get and post variables can be automatically modified to the PHP variables alternately, Which is unsafe. 8) server Variables ASP: There are many server variables. You can refer to the ASP document for an example: Request. servervariables ("http_host ") PHP: As the ISAPI mode, server variables are stored in the $ http_server_vars array. As CGI, they are stored in environment variables, using the $ http_env_vars array or getenv () . Example: $ Http_server_vars ["http_host"] Using ISAPI Module $ Http_env_vars ["http_host"] Using CGI Module 9) Database Access ASP: ADO technology PHP: Ado can be simulated using the ADODB library, which is equivalent to ADO. The limit is that read-only and roll-forward cursors are currently supported. (Annotation) You can also directly call the com library to view my article. 10) Buffering ASP: Response. Buffer = true Response. Write ("ABC "); Response. Flush () PHP: ob_start (); Print "ABC "; Ob_end_flush (); 11) script timeout ASP: seconds: Server. scripttimeout (240) PHP: seconds: Set_time_limit (240 );
