AFAIK this is not fixed in versoins beyong 4.0.1pl2 which is what I'm using.

I'm using PHP to modify Latex files - particularly to substitute PHP variables with values from a database.

Therefore my Latex file could contain:
\textbf{$php_variable}

I read lines from the Latex file and use something like:
$input_line = AddSlashes( fgets($fp));
$str = eval($input_line);

As the input line includes a {$ the eval function assumes an array calculation and the { is left out of the output string.

I've fixed the problem by adding an additional str_replace to escape the { with \{ first.

Kind regards
Mark

That's one way to fix it. Another is to use addcslashes()
instead, but you might have to upgrade your version of php
first.
