PHP Version: 5.2.13

Hello,
I can not follow you how you come to the idea not to analyze the given
source code of a bug report, simply because you do not want use your
mind to understand the logic of the source code.
For this report I made the echos in the source code that you can see the
content of the variable passed to the strpos function.
As I wrote many times, I do not doubt that the strpos function is
working in a different case and as I wrote it is working in different
places in my sourcecode. BUT !!!! As you can see strpos is not able to
find:
'article&id='
in
href="index.php?option=com_content&view=article&id=9257:2009-fha-loan-limits&catid=52:fha&Itemid=97"
in the cylcle of many nested function calls.
So - it is not a question of "strpos is working or not", but as I think
a question of memory areas which may be not correct filled, passed,
handled.....
And for that problem it is of no use to create other circumstances where
this problem is not happening.

Let me get this straight.
strpos() is used in thousands of applications around the world, and none
are experiencing this problem except yours. You claim therefore that
this is a PHP bug.
I'm sorry, but the odds are against you.
You also say, that because you reported it as a PHP bug it should be
treated as such.
I'm sorry again, but it doesn't work this way. Until you can convince us
that the problem is not with YOUR code, it will be treated as a bogus
report.
You can convince us by providing a simple code, that reproduces this
behaviour, but does not rely on external resources like database or
unknown global variables. If you can't produce such code, it's
indicating you're looking in the wrong place.
Personally I would advise using var_dump() before strpos() to see if
haystack actually contains needle.

Hello,
thank you for your suggestion, but as I reported it as a PHP bug, please
take it seriously and look for the reason that the strpos function do
not return the postiion of the string 'needle', even if the string
'needle' is contained in the string 'haystack'.

Christian, they have PHP Help forums and Joomla forums for you to use to
assist you
with your issue.
Clearly this is NOT a PHP bug more over it is just you being an
incompetent
"programmer". Please take this to a help forum, googling "php help
forum" will bring up
plenty of places that will be more than happy to help you debug your
code.

echo "j2wp_post = ".print_r($j2wp_post,1); // ADD THIS
echo "lnk_pos = ".$lnk_pos."\n"; // ADD THIS
$j2wp_wp_tb_prefix = get_option('j2wp_wp_tb_prefix');
$j2wp_joomla_tb_prefix = get_option('j2wp_joomla_tb_prefix');
echo "j2wp_wp_tb_prefix = $j2wp_wp_tb_prefix\n"; // ADD THIS
echo "j2wp_joomla_tb_prefix = $j2wp_joomla_tb_prefix\n"; // ADD THIS
the last two echo are not relevant for this problem, they are used for
mysql access.
the first two echos are too not relevant - I am doing already an echo to
the two variables I am passing to strpos!!!!!!!!!!!!!!!!!!!!!!!!!!!!
the $j2wp_post is an array with differnet fields for the wordpress posts
table. only the $j2wp_post['post_content'] field is intresting an this I
am extracting in the variable $post_lnk_string.
the variable $post_lnk_string I pass to the strpos function: To this
variable I am doing an echo. I have changed the script and printing now
the content of this variable with print_r as you suggest.
here is the source code:
echo 'Post ID: ' . $j2wp_post['ID'] . ' link: ' .
print_r($post_lnk_string,true) . ' :' . print_r($strpos_ret,true) .
':<br />';
$strpos_ret = strpos( $post_lnk_string, 'article&id=');
echo 'Post ID: ' . $j2wp_post['ID'] . ' link: ' . $post_lnk_string . '
:' . $strpos_ret . ':<br />';
$strpos_ret = strpos(
'href="index.php?option=com_content&view=article&id=9257:2009-fha-loan-limits&catid=52:fha&Itemid=97"',
'article&id=');
echo 'Post ID: ' . $j2wp_post['ID'] . ' link: ' .
'href="index.php?option=com_content&view=article&id=9257:2009-fha-loan-limits&catid=52:fha&Itemid=97"'
. ' :' . $strpos_ret . ':<br />';
// urls with structure:
href="index.php?option=com_content&view=article&id=9257:2009-fha-loan-limits&catid=52:fha&Itemid=97"
// if ( $pos_article_id = strpos( $post_lnk_string, 'article&id=') )
if ( !(strpos( $post_lnk_string, 'article&id=') === false) )
here is the output:
