Hello. I was wrong. My real problem is:
# taken from a user comment
function eval_buffer($string) {
ob_start();
eval("$string[2];");
$return = ob_get_contents();
ob_end_clean();
return $return;
}
function eval_print_buffer($string) {
ob_start();
eval("print $string[2];");
$return = ob_get_contents();
ob_end_clean();
return $return;
}
function eval_html($string) {
$string = preg_replace_callback("/(<\?=)(.*?)\?>/si",
"eval_print_buffer",$string);
return preg_replace_callback("/(<\?php|<\?)(.*?)\?>/si",
"eval_buffer",$string);
}
echo html_eval('<? if (1 == 1) { ?><? } ?>');
And this causes the error. But I don't know if it is the fault of the
user-comment-script or if the problem is in eval.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report
a bug at http://bugs.php.net/how-to-report.php
You can't have nested php-tags, try:
eval('if (1 == 1) { ?>works<? }');
in a sense your example does:
<?php <? if (1 == 1) { ?><? } ?> ?>
Which is wrong

Description:
------------
<?php
echo eval('<? if (1 == 1) { ?><? } ?>');
?>
This let a parse error in the eval appear.
The Code <? if (1 == 1) { ?><? } ?> is ok and don't let the parse error
appear.
