w/e $all is, im guessing $all->fetch() is never returning false (or a value
which can be type juggled to a boolean false equiv). if youre code is
getting beyond the while loop, then there could be something wrong w/
$all->close(); and if its getting passed that, then obviously, something
else is wrong.

In pseudo code you have:
for each result from the db
explode the issues
add another issue to the list
So:
no issues at start
row 1 fetched
explodes issues
adds another issue (1 issue)
row 2 fetched
explodes issues (now 1)
add another issue (now 2)
row 3 fetch
explode issues (now 2)
add another issue (now 3)
and so on.
So your list is getting longer and longer and you're adding to it for
each row you get from the db.

Right. It may also be worth asking exactly how the OP determined
that it's the particular function he showed.
Kyle, are you positive that your displayAll() function is even the
point of fault?

so is the code making it past the while w/ the $all->fetch() condition ? it
might be helpful to comment-out the body of said while loop and see if
script execution makes it past the while. if not, there is def something
wrong w/ $all->fetch().

please keep responses on-list for the benefit of others.
what type of class is $all an instance of, and what causes the fetch()
function to return false (or something that php can juggle to an equivalent,
such as 0).

Sorry, I was actually having a conversation about that with Daniel. It is an

You have a loop inside a loop. What makes it worse is that the loop is
growing with every iteration.
If there are 100 rows, then at the end, there are 100 entries in the
$issues array.
To get to that point, you are doing a loop of size "X" where "X" = the
row number being processed. ie row "2" is doing a foreach over 2
entries. row 15 is doing a foreach over 15 entries. row 90 is doing a
foreach over 90 entries.

That's not QUITE right. The value of $issues will always be set to the
column value for the next row when $all->fetch() is called, therefore
overwriting the value it had after the previous iteration. The
variable $row2 should be set to an empty array before the foreach loop
just in case different rows have different numbers of issues.
Iteration 1:
before foreach
$issues == 'a, b, c'
$i == 0
$iss_link == Array
(
[0] => 'a',
[1] => 'b',
[2] => 'c'
)
$row2 == empty
after foreach
$i == 2
$row2 == Array
(
[0] => '<a href="http://mantisus/view.php?id=a"; target="_blank">a</a>',
[1] => '<a href="http://mantisus/view.php?id=b"; target="_blank">b</a>',
[2] => '<a href="http://mantisus/view.php?id=c"; target="_blank">c</a>',
)
after implode
$issues == '<a href="http://mantisus/view.php?id=a";
target="_blank">a</a>, <a href="http://mantisus/view.php?id=b";
target="_blank">b</a>, <a href="http://mantisus/view.php?id=c";
target="_blank">c</a>'
Iteration 2:
before foreach:
$issues == '1, 2'
$i == 0
$iss_link == Array
(
[0] => '1',
[1] => '2',
)
/* STILL CONTAINS THE ARRAY FROM THE PREVIOUS ITERATION */
$row2 == Array
(
[0] => '<a href="http://mantisus/view.php?id=a"; target="_blank">a</a>',
[1] => '<a href="http://mantisus/view.php?id=b"; target="_blank">b</a>',
[2] => '<a href="http://mantisus/view.php?id=c"; target="_blank">c</a>',
)
after foreach:
$i == 1
$row2 == Array
(
[0] => '<a href="http://mantisus/view.php?id=1"; target="_blank">1</a>',
[1] => '<a href="http://mantisus/view.php?id=2"; target="_blank">2</a>',
[2] => '<a href="http://mantisus/view.php?id=c"; target="_blank">c</a>',
)
after implode:
$issues == '<a href="http://mantisus/view.php?id=1";
target="_blank">1</a>, <a href="http://mantisus/view.php?id=2";
target="_blank">2</a>, <a href="http://mantisus/view.php?id=c";
target="_blank">c</a>'
There is the potential for wrong behavior, but it the multiplicative
loops you are talking about shouldn't happen.

I was kinda thinking trying put a limit 1 on that sql statement might
be a worthwhile test too. Hard to really say without actually since
I've never used this particular ext.

To get to that point, you are doing a loop of size "X" where "X" = the row
number being processed. ie row "2" is doing a foreach over 2 entries. row 15

You're right, I missed that $issues was a bind_result.

What the heck is in $db? Which SQL class(es) are you using for your DB handler?

Not sure, but is your bind_results() method handling all the variable here as
pass by reference?
If so, I hope you are not expecting them to be updated as you run the while
loop below...

Usually, a while statement like this looks a little more like this...
while( $row = $all->fetch() ) {

Where are you defining the $issues variable? Where is this coming from?
I see that it will exist on the second pass through, but you need to not cause
a PHP E_NOTICE warning...

Why have a counter here??? php will take care of dynamically added an index to
an array if you call it with $row2[]

If the problem doesn't seem to be there, you could see the wrong code
snipset :D
Did check out your error log from PHP, from Apache ? ? Some time, the
segfault of Apache (due to self or PHP) cause the same effect than an
infinite loop.

This :
ltrim($line, '0123456789 .');
does remove all those characters doesn't it (as the OP asked and
Richard suggested on a previous thread). Without calling it more
than once as far as I tested. That was my point on the first place
and sorry if I didn't make that clear. On the other hand who ever
suggested calling ltrim without the second parameter.
You suggested before something like that:
ltrim(ltrim(ltrim($line, '0123456789'), '.'))
when you made a comparison didn't you?
Sorry if I got that wrong I meant no offense and I still don't.
That doesn't meet the objectives. Consider that $line might be "1. 100
apples". Your solution has reduced it to "apples" rather than the
required "100 apples".
Calling it three times as was suggested will produce the correct result.

The reason that this doesn't (maybe) work is because of the situations that
were pointed out earlier in this thread.
The following will show you why your example above will not work in all cases
$str = '01. asdf'; Yes
$str = '02.2323 asdf'; No
$str = '03. 2323 asdf'; No
$str = '04. asdf'; No /* tabs used here */
Success only 25% of the time is not good enough for me, nor should it be for
you.
But, if you were to use the regex version I described, it would work for all
above examples.
As for calling ltrim() without the second param, let me explain a little more...
ltrim(ltrim(ltrim($line, '0123456789'), '.'));
extracted looks like the following
$line = ltrim($line, '0123456789'); Removes all leading numbers, if present
$line = ltrim($line, '.'); Removes all leading periods, if present
(small problem described below)
$line = ltrim($line); Removes all leading white space, if
present (spaces, tabs, etc...)
There is still one problem with the above method.
What if you come across this. $str = '04....etc'; or $str = '04.... etc';
if the intended results for both of the last examples is just 'etc', then it
will work.
But what if it is '... etc' or '...etc', in this case, neither my regex or the
ltrim()'s will catch it.
So, in this case, you cannot program for 100% accuracy, but the closer to 100%
I can get the better the customer will feel.

I'd like to enable my users to print individual web pages from their
browser. If they simply select the browser print button they don't get
all the text that is displayed in a scrolling text area.
The web page is static html and css, in a php file.

There are some very good articles on setting up a CSS for printing web
pages if you search Google.

This might be a good starting point.

Then set out your CSS in print.css to lay out the page without scrolling
areas.

I got a lot through a tutorial, but problem is when i tried to insert,
problem occured using following code:
$query = "INSERT INTO contacts VALUES
('','$first','$last','$phone','$mobile','$fax','$email','$web')";
mysql_query($query);
But when i used a code provided by my server for same purpose was
sucessful, which was:
$sql = 'INSERT INTO `server account_database name`.`table name` (`id`,
`first`, `description`, `mobile`, `fax`, `email`, `web`) VALUES (NULL,
\'first\', \'$description\', \'$mobile\', \'$fax\', \'ghjhjhg\',
\'ghgjghjghkgk\');';
Now My problem is that :-
It supports only a single or static record at a time & from my
cpanel, but I want that the users of my website can
fill that form and when the click "submit query", then their input
should be added to the table and they can view their data...
I think that , here is a trouble in diff. version. Please If you give
me the code(query").
With this hope that you will surely reply me at [EMAIL PROTECTED]

<!-- SNIP -->
Your query looks fine. You need to look at the error codes you receive.
change:
mysql_query($query);
TO:
mysql_query($query) or die(mysql_error());
The resulting error message should help you find your MySQL issue.

You can only omit the fields you are adding data to in an INSERT query
if you are inserting data into ALL the fields, and in the order they
occur in the table.
However, I'm not sure quite what your problem is, could you give some
more details?

I browse on my phone with an older version of Opera, which doesn't
support much (if any?) Javascript, and I do turn it off in normal
browsers to see how things work, although mostly this is with my own
stuff, so I can make sure it is good in terms of SEO and accessibility.

Here is what you're doing wrong.
I'm 99% sure you have applied it in wrong place and have your data sent out
already destroyed by addslashes.
Only 2 places where any escaping should occur:
1. before writing data to storage, use appropriate storage-dependent escaping
routine.
2. before sending data to client. Use appropriate encoding routine, such as
htmlentites()
Don't use add*slashes and any kind of it, including magic_quotes*, unless you
surely know what you're doing and why.
And please, don't top-post.

Probably not the right list, but have you tried using cyradm and
running: reconstruct user.name.mailbox.name
(correct the folder as needed).
When a cyrus database file gets corrupted or generally borked this fixes
it 99% of the time for me.
