Let's Learn Coding .: 2013

tonight.. i just playing with PHPcoding.

Start with login page but first i will create new folder in my server.

[dora@localhost public_html]$ mkdir project2
[dora@localhost public_html]$ ls
project1  project2  rnd  smf  test

[dora@localhost public_html]$ cd project2
[dora@localhost project2]$ nano -w index.php


<html><head><title>Title</title></head><body>
<form method="post" action="login.php">
<label>Username</label>: <input type="text" name="username" />
<br />
<label>Password</label>: <input type="password" name="password" />
<input type="submit" value="Log In" />
</form>
</body></html>






done.

then i do the "processing"

[dora@localhost project2]$ nano -w login.php



[?php

$username = $_REQUEST['username'];
$password = $_REQUEST['password'];

if ($username === 'Darlinx' && $password === 'Darlinx') 
echo "Password correct";
else echo "Password incorrect";



Form eXplaination ::

[?php = is a tag to php form.

in this process the form will received input.
it will retrieve from global << [input name="username"

$username $password = example of variable.

echo = is for output. print as 'text'

** when u submit the first form (login) the data will be
   transfer to login.php

now we need a comparison. I will set the input for "username" & 
"password" here. :)







ok. now i want to create "table" in my form.

let say i hav $x number of rows & $y number of columns
create new php file.

[dora@localhost project2]$ nano -w table.php

<?php

$x = 3;
$y = 5;

echo "<table>";
border="1"
for ($i = 0; $i < $x; $i++){
        echo "<tr>";
        for ($j = 0; $j < $y; $j++){
        }
                for ($j = 0; $j < $y; $j++){
                echo "<td>row $i col $j</td>";
                }
}
echo "</table>";



form eXplaination :

** this is what we call nested loop

LOOP ROWS WHILE ROWS IS LESS THAN 3
     PRINT ROW OPENING
          LOOP COLUMNS WHILE ROWS IS LESS THAN 4
               PRINT COLUMN WITH ROW NUMBER AND 
               COLUMN NUMBER
          LOOP END
     PRINT ROW CLOSING
LOOP END




try to add border since. :X

but.. that's how the loop working. i understand now. :)

Re-arrange my files in shell . Flashing back all the tutorial.

what i do .?

     [dora@localhost ~]$ ls
     BNC.docx  chrome-mac.zip  public_html  smf_2-0-2_install.tar.bz2

     [dora@localhost ~]$ cd public_html
     [dora@localhost public_html]$ ls
     project1  project1.tar.bz2  rnd  smf

     [dora@localhost public_html]$ cd ..

     [dora@localhost ~]$ ls
     BNC.docx  chrome-mac.zip  public_html  smf_2-0-2_install.tar.bz2
     [dora@localhost ~]$ rm -rf chrome-mac.zip
     [dora@localhost ~]$ ls
     BNC.docx  public_html  smf_2-0-2_install.tar.bz2

     [dora@localhost ~]$ cd public_html
     [dora@localhost public_html]$ ls
     project1  project1.tar.bz2  rnd  smf
     [dora@localhost public_html]$ rm -rf project1.tar.bz2
     [dora@localhost public_html]$ ls
     project1  rnd  smf

= deleting un-neccessary files.

i think i want to separate the code with compiler that i have save
in folder rnd. It's mixed. So i create one new folder for that.

     [dora@localhost public_html]$ mkdir test
     [dora@localhost public_html]$ ls
     project1  rnd  smf  test

     [dora@localhost public_html]$ cd rnd
     [dora@localhost rnd]$ ls
     a.asm  a.s          testcode.php   testcode2.php  testcode4.php  
     testcode6.php a.c    iframe.html  testcode1.php  testcode3.php  
     testcode5.php

it's so mixed.! :X

after test and error many cmd .. and googling -
i found this 

     [dora@localhost rnd]$ mv a.s a.c a.asm ../
     [dora@localhost rnd]$ ls
     iframe.html   testcode1.php  testcode3.php  testcode5.php
     testcode.php  testcode2.php  testcode4.php  testcode6.php

     [dora@localhost public_html]$ ls
     a.asm  a.c  a.s  project1  rnd  smf  test

now only i can use this ::

     [dora@localhost public_html]$ mv a.asm a.s a.c test/
     [dora@localhost public_html]$ ls
     project1  rnd  smf  test

     [dora@localhost public_html]$ cd test
     [dora@localhost test]$ ls
     a.asm  a.c  a.s

ok done.

try and error to use gcc. :X

** noted : it's (.s) for assembler. not (.asm)  :P

     [dora@localhost test]$ nano -w a.c

      
      
      #include [stdio.h]
      main()
      {
      printf("Hello World!");
      }
      

      [dora@localhost test]$ gcc -o a a.c
      [dora@localhost test]$ ls -a
      .  ..  a  a.asm  a.c  a.s
      
      [dora@localhost test]$ ./a
      Hello World![dora@localhost test]$ 

c is done . 

Im just trying using the same cmd for the assembly coding.
In my last post.. i have do the assembly code in windows
and i use "Visual Studio Express 2010"

now i want to take the code and try to see how it will compile in nano.

       [dora@localhost test]$ nano -w a.s

[dora@localhost test]$ 

ouch .! stuck ...... dunno whut to do. 
i must change the coding.. i will googling for that. 

09/01/2013

the new code.... 

       [dora@localhost test]$ nano -w a.s

       
       
#TITLE Test

#Description:
#This progam adds and subtracts 32-bit unsigned
#integers and stores the sum in a variable
#Revision date:

INCLUDE "Irvine32.inc"

main:

 mov   eax,1
 call DumpRegs ;1st value
 call DumpRegs ;2nd value

 mov   ebx,0 ; initial setup
 mov   edx,1
    mov   ecx,6 ; count

L1:
 mov  eax,ebx ; eax = ebx + edx
 add  eax,edx
 call DumpRegs ; display eax
 mov  ebx,edx
 mov  edx,eax
    Loop L1



I have modified a bit. now it look smooth in upper. I must replace
the coding to more simple one. 

         [dora@localhost test]$ gcc -o a a.s

a.s: Assembler messages:
