ASP to PHP translator Copyright 2002-2005 Robert Giordano. All Rights Reserved Update 10.03.2015 ----------------- I've just updated the site to HTML5 and I believe I've fixed the problem with the registration emails. I haven't added any new features to the Translator but if I get enough requests, I might do it. Even though this thing is ten years old, it works pretty well as it is. Enjoy! What's new in v2.16 02.24.2005 ------------------------------- • Supports #INCLUDE FILE • Supports Response.redirect • Converts Asc, Replace, Split • Dynamically added comments help you debug Overview -------- The ASP to PHP translator saves you valuable time by performing the following time consuming and tedious tasks: • ASP tags Converts all <% to <?, works with multiple embedded tags per line. NOTE: if there are no <% tags in the entire text, the translator assumes the text is ALL ASP code. • ASP variables Finds all ASP variables and prefixes each with $, without affecting html. Also, array variables are converted from var( ) to var[ ]. • Comments ASP comments starting with ' are converted to // style comments. This is done without affecting the inline use of apostrophes. • Semicolons Adds ; to the end of each line of script, without affecting html. This is done intelligently so semicolons are added inside of { } when necessary. • Scripting Translation The following table shows the script elements translated in this version: ASP script PHP Translation ---------------------------------------- ---------------------------------------- If a=b Then ... End if if ($a==$b) {...} If a=b Then ... Else ... End if if ($a==$b) {...} else {...} For a=1 to 5 ... Next for($a=1; $a<=5; $a++) { If a>b Then Exit For if ($a>$b) {break;} Next } Function doThis(x) function doThis($x) { If x=0 Then Exit Function if ($x==0) {break;} doThis=y 'return value return $y; //return value End Function } Sub doThis(x) ... End Sub function doThis($x) {...} "x="& x &", y="& y "x=".$x.", y=".$y; x and (y or z) $x && ($y || $z) if IsNumeric(a) then ... if (is_numeric($a)) {... Asc(a) ord($a); Int(x) floor($x); x=Request.QueryString("id") $x=@$_GET["id"]; n=Request.Form("username") $n=@$_POST["username"]; s=Request.ServerVariables("SERVER_NAME") $s=@$_SERVER["HTTP_HOST"]; p=Request.ServerVariables("SCRIPT_NAME") $p=@$_SERVER["PHP_SELF"]; Response.redirect("wrong_link.htm") header("Location: wrong_link.htm"); #INCLUDE FILE="_config.asp" include "_config.asp"; Now date("n/j/Y g:i:s A"); vbCrLf "\n" Len(a) strlen($a); a=LCase(b) $a=strtolower($b); a=UCase(b) $a=strtoupper($b); a=Split(temp,",",-1,1) $a=explode(",",$temp); temp=Replace(temp,"<","[") $temp=str_replace("<","[",$temp); • Intelligent Quote Handling The following table illustrates how complex quoted sections of ASP are translated: ASP string PHP Translated string ---------------------------------------- ---------------------------------------- Response.Write("Wow!!") echo "Wow!!"; Response.Write("""Wow!!""") echo '"Wow!!"'; Response.Write("This "& i &" that") echo "This ".$i." that"; Response.Write("x["& i &"]='"& mx &"';") echo "x[".$i."]='".$mx."';"; Response.Write("John's is """& xp &"""!") echo 'John\'s is "'.$xp.'"!'; emsg="<span class=""s2"">"& mx &"</span>" $emsg='<span class="s2">'.$mx."</span>"; Performance (on computers/browsers from 2005) --------------------------------------------- The ASP translator uses client side Javascript for all translations. Because of this, performance will vary depending on the browser and platform used. Here are some test results using a test page with 330 lines of ASP script, 67 ASP variables, 72 lines of HTML and many of the ASP script variables embedded within the HTML: AMD 2400mhz, Windows 2000 Pro -------------------------------------- Internet Explorer 6 0.39 sec Firefox 1.0 PR 0.73 sec Netscape 6.2 2.53 sec Opera 7.54 2.68 sec Pentium III, 1000mhz, Windows 2000 Pro -------------------------------------- Internet Explorer 5 0.84 sec Netscape 6.2 5.95 sec Netscape 4.7 44.53 sec (no one still uses Netscape 4 on the PC, right?) Macintosh Powerbook G4, 800mhz, OSX -------------------------------------- Chimera 0.6 1.77 sec Internet Explorer 5.2 2.03 sec Safari beta 1.0 5.06 sec (a little disappointing, but acceptable) Macintosh G3, 233mhz, OS9 -------------------------------------- Netscape 4.6 4.05 sec (whoa!! Mac Netscape kicked ass back in the day!!) String Function Library ----------------------- Some ASP Programmers find the conversion to PHP a bit tedious because the string handling functions in PHP are quite different. The following PHP functions can be included with your scripts so that no substitution of the familiar ASP string functions is necessary: // ASP to PHP string functions from rob@design215.com // -------------------------------------------------- function left($s,$x) {return substr($s,0,$x);} function right($s,$x) {return substr($s,$x*-1);} function mid($s,$x,$w="") { //$w is optional if ($w) {return substr($s,$x-1,$w);} else {return substr($s,$x-1);} } function instr($n,$s) {return strpos(chr(0).$n,$s)+0;} //v1.2 function instrrev($n,$s) { $x=strpos(chr(0).strrev($n),$s)+0; return (($x==0) ? 0 : strlen($n)-$x+1); } // -------------------------------------------------- NOTE: The translator converts "Left", "Right", "Mid", and "inStr" to lower case. Javascript and html are not affected. Limitations ----------- This utility has proven to be fairly reliable. New features will be added as time allows. There are many complex cases of embedded ASP within html so you will still have to check each line of translated code for errors. As stated earlier, this utility does not rewrite your code. The following limitations have been found in the current version of this utility: > Only works with VBScript, JScript is ignored > Single lines of ASP embedded within html code may not get a ; > There are some commands for which no substitutions are done yet. > You will have to rewrite any SQL database connections.
