1) Output 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 provided automatically as a global variable, if configured in the php.ini file:
Variables_order= "Egpcs"
Register_globals=on
For security, I will not allow register_globals (set it to off). The variable is then used only in the array:
$HTTP _post_vars, $HTTP _cookie_vars and $HTTP _get_vars.
3) REDIRECT Address
Asp:Response.Redirect (Newurl)
Php:header ("Location: $newurl");
4) Cookie Processing
Asp:Response.Cookies (CNAME) = newval
Val= Request.Cookies (CNAME)
Php:setcookie ($cname, $newval);
$val = $HTTP _cookie_vars[$cname];
5) Application variable
Asp:application (Appvarname)
PHP: This variable is not provided and can be emulated in other ways, such as a database
6) Session Variable
Asp:session (sessionname) = newval
Val= Session (sessionname)
PHP: In PHP4 or later versions, we determine the variable as a session in the
Session_register ($sessionname), and then we call Session_Start ()
The session variable value is restored at the beginning of the. php page to be used.
As an example:
Session_register (' Val ');
$val = 88;
Session_Start ();
Print $val;
7) Form variables
Asp:Request.Form ("FVal")
Request.QueryString ("FVal")
PHP: $HTTP _post_vars["FVal"];
$HTTP _get_vars["GetVar"];
The Get and POST variables can be automatically modified to the PHP variable alternately, which is unsafe to the method.
8) Server variables
asp: There are many server variables that can be seen in ASP documents. An example:
Request.ServerVariables ("Http_host")
PHP: As an ISAPI mode, server variables are stored in the $http_server_vars array.
As CGI, they are stored in environment variables, with $http_env_vars arrays or getenv ()
Can get. An example:
$HTTP _server_vars["Http_host") using ISAPI module
$HTTP _env_vars["Http_host"] using CGI module
9) Database access
asp: General ADO Technology
Php:ado can be modeled using the ADODB library, which is equivalent to ADO.
The limit is that the read-only cursor and the roll forward cursor are currently supported.
10) Cache Buffer
Asp:Response.Buffer = True
Response.Write ("AAA");
Response.Flush ()
Php:ob_start ();
print "AAA";
Ob_end_flush ();
One) Script Timeout
asp: The time level is the second level:
Server.ScriptTimeout (360)
PHP: Time-level is the second level:
Set_time_limit (360);
If there is a mistake, please advise us.
The above describes the PHP and ASP object equivalence relationship, including the aspects of the content, I hope that the PHP tutorial interested in a friend helpful.
