At first: I am ConTeXt-newby and know PHP very well.
@Peter Münster/Aditya Mahajan : I think \startasci and
\stopasci is not the solution, when you generate
ConTeXt-code with php full of ConTeXt-macro-calls:
because sometimes the special-characters are
ConTeXt-special-characters and sometimes they are purely the
wanted text.
@Philipp Gesang: I think Luatex could do the same job for me
as PHP - however I am familar with PHP.
@all: of course not every Character, i am converting, is a
ConTeXt-special-character. Though I don't know all important
characters I took all I could imagine. Shurly I converted
too much however it is no problem:
I have tested my function "ConvertToConteXt" with 400 Pages
full of text and lots of ConTeXt-special-characters and
ConTeXt-macro-calls and compiled a nice book with ConText.
Which character must not be converted?
I had a mistake in the function, below is the next version:

function ConvertToConteXt ( $xstring ) {

*
* Convert special ConTeXt-characters with php
* Works with PHP5
*
* Call it with the string you want to convert ...
* ConvertToConteXt ($xstring);
*
* ... and you get back the converted string
*
* e.g.:
* Input:
* $string = "My root-Directory: /home/hans";
* $string = ConvertToConteXt ( $string );
*
* Output/Return:
* $string = "My root\\char45Directory\\char58
\\char47home\\char47hans";
*
* When you write this into a file ...
* file_put_contents ( "example.tex", "My
root\\char45Directory\char58 \\char47home\\char47hans",
FILE_APPEND );
*
* ... You will find the following in example.tex:
* My root\char45Directory\char58
\char47home\char47hans
*
* An when you compile example.tex with ConTeXt
* context example.text
*
* You can read the following in the resulting
example.pdf:
* My root-Directory: /home/hans
*
