as you can see, PHP does not find the string in the variable and the

yes it does not work !!!
I get the result 40 if I put it directly as string in the function, but
in the variable it does not work.
Here the browser output:

As you can see the Post ID 107 there is the string, but the output is
generated in the else tree of the if statement.
the whole script you can find under:

Based purely on your bug description, you are saying this doesn't work?
<?php
$haystack =
'href="index.php?option=com_content&view=article&id=9257:2009-fha-
loan-limits&catid=52:fha&Itemid=97"';
$needle = 'article&id=';
echo strpos($haystack,$needle);
When I run this I get: 40
which looks correct.
Please simplify your reproduce code and I bet you will find that your
mistake is
elsewhere.

Description:
------------
Hello,
I try to find a string in another string using strpos. If both the
string are passed to the strpos function enclosed in ' it is working
properly and the position is returned. If I put the string - in which
the other string has to be find - in a variable and pass the variable to
the strpos function I get FALSE.
Maybe a problem of character conversion or php configuration????
the website is: joomla-wp.it-gnoth.de
with it-gnoth.de/phpinfo.php your will see the complete configuration.
the string which is to be searched:
href="index.php?option=com_content&view=article&id=9257:2009-fha-loan-limits&catid=52:fha&Itemid=97"
the string which has to be find:
article&id=
below the php source code - both if version get the same result. It goes
always in the else tree.
Test script:
---------------
function j2wp_change_single_url( $j2wp_post, $lnk_pos )
{
global $CON,
$wpdb;
$j2wp_wp_tb_prefix = get_option('j2wp_wp_tb_prefix');
$j2wp_joomla_tb_prefix = get_option('j2wp_joomla_tb_prefix');
$permalink = false;
// $lnk_pos ---> pos at href=" string in post_content
// $post_lnk_end ---> pos at last " in link string of
post_content
// $post_lnk_string ---> contains the whole link string inkl. " at
the end
$post_lnk_end = strpos( $j2wp_post['post_content'], '"',
$lnk_pos + 7);
$post_lnk_string = substr( $j2wp_post['post_content'], $lnk_pos,
$post_lnk_end - $lnk_pos + 1 );
if ( !(strrpos( $post_lnk_string, '/') === false) )
$pos_lnk_last_slash = strrpos( $post_lnk_string, '/');
// urls with structure:
index.php?option=com_content&view=article&id=9257:2009-fha-loan-limits&catid=52:fha&Itemid=97
// if ( !(strpos( $post_lnk_string, 'article&id=') === false) )
if ( $pos_article_id = strpos( $post_lnk_string, 'article&id=') )
{
$pos_article_id += 11;
$article_id = j2wp_extract_number( substr( $post_lnk_string,
$pos_srticle_id ) );
$url_post_id = j2wp_get_post_url_for_id( $article_id );
$permalink = get_permalink( $url_post_id );
}
else
