Christian,
once you do the echo on $post_lnk_string, use the View Source from the
browser.
Your links are not &, they are &
This is what I found in your SQL dump for the "link 107":
index.php?option=com_content&view=article&id=9257:2009-fha-loan-limits&catid=52:fha&Itemid=97
See... there is no "article&id=" there.

The set of steps required to reproduce your problem is rather long.
Hopefully
you realize now why we aren't falling over ourselves reproducing your
environment just to find your bug for you.
How about this:
Just before your strpos call, add this:
file_put_contents("/tmp/debug.txt",$post_lnk_string);
Then run this script:
<?php
$post_lnk_string = file_get_contents("/tmp/debug.txt");
var_dump(strpos($post_lnk_string, 'article&id='));
If that is still broken, you now have a small reproducing script. If
you can't
figure out your problem by looking at /tmp/debug.txt then zip or tar it
up and
make it available to use somewhere.
Hint, I bet your & is actually & or you have a non-printable char in
there,
somewhere which you can check by doing: od -c /tmp/debug.txt

Ok.
Using:
$post_lnk_string =
'href="index.php?option=com_content&view=article&id=9257:2009-fha-loan-limits&catid=52:fha&Itemid=97"';
$strpos_ret = strpos($post_lnk_string, 'article&id=');
var_dump($strpos_ret);
This script is exactly what you are doing. The output is:
int(40)
It works.
Your analyze about the memory are is wrong. Please check the
implementation if you like to verify it by yourself.

Hello,
thank you for your qualified answer. But, please take a look at the
following lines:
$strpos_ret = strpos( $post_lnk_string, 'article&id=');
echo 'Post ID: ' . $j2wp_post['ID'] . ' link: ' . $post_lnk_string . '
:' . $strpos_ret . ':<br />';
and here is the output:
Post ID: 107 link:
href="index.php?option=com_content&view=article&id=9257:2009-fha-loan-limits&catid=52:fha&Itemid=97"
::
So the strpos function has no idea from were the input is comming.
Infact it is for the problem not intresting. Question is, from which
memory area it gets the input and what is there and how it is moved to
the strpos function.
The variable which is passed to strpos contains the string
'article&id=', but this string is not found by the strpos function.
So it is a bug in the PHP interpreter!!!
As you are the developer you should see that!!!

Please understand that strpos has absolutely no idea where the strings
you pass it come from (ich meine es: echt keine Ahnung).
What is so hard to understand to actually do what Rasmus has been asking
for a week now? Provide a script like the one I wrote in my previous
comment.
If you can't reproduce it using such a simple script, then something is
wrong somewhere else in your code.
If you keep need support, I would suggest to go to either the
php-general mailing or to whatever is the support channel for Wordpress.
But bugs.php.net is not such channel.
Thanks for your understanding.
