Thank you very much, that does almost what I wanted. I made a few changes
to make the script work and then I changed it to check if the string was
already in the .php files and if it is, it uses it.
Since I don't know regular expressions and it's the first time I'm using
lisp, I guess this is a terrible code, but it works

Once again, thank you for your help.
I left here the final code I'll be using:
(defvar *ds-languages-dir* "languages")
(defvar *ds-php-file* (format "%s/pt.php" *ds-languages-dir*))
(defvar *ds-php-buffer* ())

(defun  ds-create-lang-entries ()
 "Change the selection in the current buffer and create a PHP definition in
the PHP file.
The change to make is
   \'\'
        --> \'<xsl:value-of select=\"/xml/lang/_MATCHED_STRING\" />\'.
The addition to the PHP file is made at the end of the file;
it is \'DEFINE(\"_LANG_MATCHED_STRING\", \"%s\");\'."
 (interactive)
 (ensure-php-buffer)
 (let ((xsl-format "<xsl:value-of select=\"/xml/lang/_%s\" />")
       (php-format "DEFINE(\"_LANG_%s\", \"%s\");\n")
       (oldbuf (current-buffer))
       (the-string (buffer-substring-no-properties (point) (mark))))
   (save-current-buffer
      (set-buffer *ds-php-buffer*)
      (if (search-backward the-string nil t)
        (progn
  (let ((endpoint (- (point) 4)))
    (search-backward "DEFINE" nil t)
    (let ((the-constant (buffer-substring-no-properties (search-forward
"_LANG_") endpoint)))
              ;; Change the selected text to the appropriate XSL
      (set-buffer oldbuf)
              (delete-region (point) (mark))
              (goto-char (mark))
              (insert (format xsl-format the-constant)))))
 (progn
  (set-buffer oldbuf)
            (let* ((the-constant (replace-regexp-in-string " " "_" (upcase
(read-from-minibuffer "constant: ")))))
              ;; Change the selected text to the appropriate XSL
              (delete-region (point) (mark))
              (goto-char (mark))
              (insert (format xsl-format the-constant))
              ;; <xsl:value-of select="/xml/lang/_BIG_TEXT" />
              (save-excursion
                (set-buffer *ds-php-buffer*)
                (goto-char (point-max))
                (insert (format php-format the-constant the-string)))))))))

(defun ensure-php-buffer ()
 "Make sure that everything about the PHP buffer is good."
 (unless (file-directory-p *ds-languages-dir*) (make-directory
*ds-languages-dir* t))
 (unless *ds-php-buffer* (setq *ds-php-buffer* (find-file-noselect
*ds-php-file*))))

(local-set-key "\C-c\C-c" 'ds-create-lang-entries)
