Summary: strpos not working correctly
Status: Bogus
Type: Bug
Package: Strings related
Operating System: Linux
PHP Version: 5.2.13
New Comment:
If you are experiencing a problem with strpos and variables, then please
provide a script similar to:
$haystack = "some content";
$needle = "content";
if (strpos($haystack, $needle) === false)) {
echo "not found\n";
} else {
echo "found\n";
}
Everything else is irrelevant.
However, as Rasmus said, there is no difference in strpos if you pass a
static variable or a string.

Hello,
that 5 lines are working - I do not doubt. That is not the problem here.
Again, strpos is working with static strings passed, but with
variables.
That is a fact as you can see it. The output is generated at the only
position in the else tree!!!! So with strpos working correctly it should
never go there for that string!!!
If you like, I can send you the MySQL dump file and the php script.

Your bug is elsewhere. There is no difference between passing a static
string and
passing a variable. The only difference happens if the contents of the
variable
is different. Write a 5-line script that reproduces the problem and you
will see.

as you can see the strpos function works also in my script it returns
the position 40, but only in the static passing of the strings. In the
work process - the function is called for each url - somehow the
variables are not processed correctly (maybe some problem in the memory
areas???). The content of the variables is shwon correctly through the
echo construct, but the content is not processed correctly by the strpos
function.

here the changed script:
// $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, '/');
$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) )
{
$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
{
as you can see, PHP does not find the string in the variable and the
working process!!!
