This is the result:
"\214\t\303n\320Lz\330\271\252\017\355\036\251|\237\212V\270hq

what is that? \214???\t\303n?

The .inspect version of a string escapes non-ascii characters. \214
means "the character with the byte value of octal 214, decimal 140".
\t is a tab character.
Remove the .inspect from your above and you'll see something more like
the python values you seem to have been expecting.
thank you, but I'm having a lot of problems anyway
This is the new code:
ruby code:
···
-------------------------------
#!/usr/bin/env ruby
require 'openssl'
text = "abcdefghijklmnopqrstuvwxyz"
key = "altakey"
alg = "AES-128-ECB"
file_name = "test.encrypted"
file_name_2 = "test.decrypted"
puts %(clear text: "#{text}")
puts %(symmetric key: "#{key}")
puts %(cipher alg: "#{alg}")
puts "--Encrypting--"
des = OpenSSL::Cipher::Cipher.new(alg)
des.encrypt(key)
cipher = des.update(text)
cipher << des.final
puts %(encrypted text: #{cipher.inspect})
puts
file = File.open(file_name, "w")
file.truncate(0)
file << cipher
file.close
---------------------------------------
The result:
---------------------------------------

---------------------------------------
This is the php code:
---------------------------------------
$text = "abcdefghijklmnopqrstuvwxyz";
$key = "altakey";
$alg = "AES-128-ECB";
$file_name = "test.encrypted";
$file_name_2 = "test.decrypted";
echo "decrypted content: $text\n";
echo "key: $key\n";
$result = mcrypt_encrypt ( MCRYPT_RIJNDAEL_128 , $key, $text,
MCRYPT_MODE_ECB);
echo "result: $result\n";
$file = fopen($file_name, "w");
fwrite($file, $result);
fclose($file);
----------------------------------------
The result (with a warning):
Warning: mcrypt_encrypt(): Attempt to use an empty IV, which is NOT
recommend in
/usr/local/src/ruby/ruby-1.8.4/sample/openssl/test.encrypt.php on line

And finally, an openssl version:
----------------------------------------
#!/bin/bash
openssl enc -aes-128-ecb -in test.original -out test.encrypted
----------------------------------------
The result:
----------------------------------------

They are throw different results, but the encription algorithm is the
same and the key is the same
