Thx, a lot - I think create_function() is *exactly* what I searched for. I wondered what create_function() is for in the lambda-war two weeks ago or so... I did not find any doc on how to use it and the code snipplet provided two weeks ago or so was not very clear. Could you tell me where to search for documentation on how to use it. regards Stanislav Malyshev wrote:

So, why can't you use require, I don't see? Another solution - use create_function (or whatever name was decided on lambda at the end) to compile the code and then run it multiple times. w>> w>> <?php w>> $string=<<<END w>> $i+1; w>> $a='test'; w>> END; w>> ?> w>> w>> It is simply *impossible* to store the real *unevalulated* string w>> >> $i+1;\n$a='test'; << into $string, because HERE DOCS evalulate every w>> line (@dave: that?s perhaps the *reason of slowlyness*) - it would be Wrong. Heredoc evaluates nothing, it just resolves variables. But I think that's what you were meaning. Use \$ instead of $ if you don't want it (yes, preg_replace on user-supplied data).

Perl has <<"MARK" and <<'MARK' for this.
