Re: [PHP] what to use instead of foreach

 I have already tried with several count and for schemes. None work
 because foreach ignores any counters once in the loop. Also, this
 foreach is nested within another foreach; don't know if that affects
 anything.


Have you heard of while()? You can use it in combination with
array_pop() and count()

like:
?
while (($data = array_pop($array)) !== NULL) {
/* having $data and count($array) changes with every loop */
}
?

Hi PJ,

Maybe you should post your code, or portion thereof. The trained eyes on the
list will quickly gather where the problem in the logic lies. 

Maybe you can also sacrifice some of your data or data structures if not too
sensitive. This will help to validate the route you are trying to follow.

Best wishes
Leon

Good suggestion Leon, thanks.
I can certainly do that, np. Nothing sensitive. I do have quite a few
questions about the code I have used. Things are moving along very well
and I should be able to put up the code on the actual site in some
directory where it will be possible to view the code and see what it is
doing. I'll post the link when more or less ready and then ask for
comments, observations, suggestions . Posting the code on the list would
be too bumbersome. For now, I'll stick to some snippets. :-)

 foreach doesn't give a damn about count so you can't use that - it is
 reset once inside the foreach loop.

Look again at the code - the count() is not inside the foreach, so it is 
not reset, simply stored in $lastIndex for comparison.

If your array is associative then simply use another variable to find the 
last value in the array - the code doesn't need to change much.

Try actually running the code below - it does work, as does the previous 
version I posted if the array is not associative. 

I'd prefer it if in future you didn't tell me that my code didn't work 
without actually trying it - I tested that snippet before posting it, as I 
did with the following.

?php
// Non-associative array (the code I posted previously).

$lastIndex = count($a) - 1;
$outputString = '';
foreach ($a as $index = $value) {
if ($index != $lastIndex) {
$outputString .= $value, ;
} else {
$outputString = rtrim($outputString,', '); // Strip last comma.
$outputString .=   $valuebr /;
}
}
echo $outputString;

// Associative array (changed only very slightly).
$a = array('martha' = '1','jock' = '2','dave' = '3');

$lastIndex = count($a);
$counter = 0;
$outputString = '';
foreach ($a as $index = $value) {
$counter++;
if ($counter != $lastIndex) {
$outputString .= $value, ;

$outputString = rtrim($outputString,', '); // Strip last comma.
$outputString .=   $valuebr /;

My apologies. It certainly was not meant to disparage the suggestion. I
had tried all sorts of counts as I mentioned before. I spend an awful
lot of time testing and trying but I'm afraid I don't really grasp all
the concepts involved. I am rather visually oriented and not seeing

I shouldn't assume so much and will certainly examine your suggestion

Like that? If your array is associative you can drop the $lastIndex calc 
and adjust the loop to update a counter instead.

foreach doesn't give a damn about count so you can't use that - it is
reset once inside the foreach loop. And, the as $index cannot relate
to the $lastIndex because the array index (which would be the index in
the as $index) can be any number and is not sequential. There are a
couple of other ways, one is suggested by Jim Lucas in the thread
extract varying data from array with different formatting; another is
to change the SELECT query to use a ranking reference - I think it may
be a bit more complex, though.
Any other thoughts? ;-)  I'll appreciate them.

Re: [PHP] what to use instead of foreach

Hi Leon,
Thanks for the suggestion; I'm quite new to all this, so it's a bit
complicated for my peanut brain.
I have already tried with several count and for schemes. None work
because foreach ignores any counters once in the loop. Also, this
foreach is nested within another foreach; don't know if that affects
anything.
I'll try to understand the second suggestion using for. I'll see what
comes up.
There are actually several conditions that have to be met:
1. if only 1 author = echo authorbr
2. if 2 authors = echo author  author1br
3. if more than 2 authors = echo author, author1, author2  author3br
That's what makes it a toughie

Leon du Plessis wrote:

 $b = 1;

 }

 Or there are some different ways to approach this also like:
 for ($a = current($my_array); $a; $a = next($my_array))
 {
 //Format 1
 echo  $a ;
 $a = next($my_array);

 This way you have some added control over the iteration through the array,
 and you can play around with when  how to display what.

RE: [PHP] what to use instead of foreach

[Leon du Plessis]

Hi PJ, 

Ok, If I understand correctly you can attempt to alter your code as per
following example (I am breaking it down a little for readability):

a) If you only wish to output the authors, see also Mark Kelly's example,
You can simply output as many authors you have associated (you will need an
associated array!!:

Or b) I include the following alternative example:


$string_out = :
Foreach ($my_titles as $titles)
{
   Echo Title: $titles By:br;
   Foreach($my_authors[$title] as $author)
  $string_out .= $author, ; /* Building string */

   // Add br
   $string_out .= br;

   // Here you would replace your last comma with the  you want
   // There are a few ways to do this (like Mark Kelly's), but will try 
   // another way (older, maybe less complicated?).
   $final_string = substr($string_out,0,strrpos($string_out,,) - 1);
   $final_string .=. 
  substr($string_out,strrpos($string_out,,) + 1);
}


So all you need is to modal your data around this, and you should be fine. 
You could construct your arrays then as follows as an example:


$my_titles = array(title1,title2);
$my_authors[title1] = array(a someone,a notherone);
$my_authors[title2] = array(mr. a,mr. b);
... 

and so forth...how you construct the data is then very important as you can
then later use it simplify your coding as you progress and as demonstrated
below:

In future, where the need justifies it, you can construct your array to
already contain the needed string you want to output, it may help, but you
will sometimes have the same effort in constructing the data for the arrays,
so it is up to you to decide which approach is going to be best: e.g.
$my_titles = array(title1,title2);
$my_authors[title1] = array(a someone, a notherone  Mr. X);

Then you can simply echo the array value:
echo $my_authors[title1] . br;

Hope it is enough info for to work on for now!!

Have fun!
Leon

Re: [PHP] what to use instead of foreach

[PJ]

Hi Leon  thanks.
It sure is complicated. Jim Lucas example did the trick very nicely (in
my other post -
extract varying data from array with different formatting but here I
am learning about other ways  means.
Redoing the arrays means redoing the queries :-(  but I'll have a go at
it if I'm to learn anything. I already have a ranking column set up but
am not using it at the moment for the author display. Anyway, I have
enough to keep my neurons busy for a while.
Thanks.

 I have already tried with several count and for schemes. None work
 because foreach ignores any counters once in the loop. Also, this
 foreach is nested within another foreach; don't know if that affects
 anything.
 I'll try to understand the second suggestion using for. I'll see what
 comes up.
 There are actually several conditions that have to be met:
 1. if only 1 author = echo authorbr
 2. if 2 authors = echo author  author1br
 3. if more than 2 authors = echo author, author1, author2  author3br
 That's what makes it a toughie

 }

 This way you have some added control over the iteration through the
 array,
 and you can play around with when  how to display what.

 foreach does not allow for different formatting for output...
 What could be used as a workaround?
 example:
 echo $some_result, br; // will print all results in 1 column
 echo $some_result, ,; // will print all results comma-separated in
 1 row

 But how do you get result1, result2  result3 // with br at end ?

 Hi Leon  thanks.
 It sure is complicated. Jim Lucas example did the trick very nicely (in
 my other post -
 extract varying data from array with different formatting but here I
 am learning about other ways  means.
 Redoing the arrays means redoing the queries :-(  but I'll have a go at
 it if I'm to learn anything. I already have a ranking column set up but
 am not using it at the moment for the author display. Anyway, I have
 enough to keep my neurons busy for a while.
 Thanks.

  Hi PJ,
 
  Ok, If I understand correctly you can attempt to alter your code as per
  following example (I am breaking it down a little for readability):
 
  a) If you only wish to output the authors, see also Mark Kelly's example,
  You can simply output as many authors you have associated (you will
  need an
  associated array!!:
 
  Or b) I include the following alternative example:
 
  
  $string_out = :
  Foreach ($my_titles as $titles)
  {
  Echo Title: $titles By:br;
  Foreach($my_authors[$title] as $author)
  $string_out .= $author, ; /* Building string */
 
  // Add br
  $string_out .= br;
 
  // Here you would replace your last comma with the  you want
  // There are a few ways to do this (like Mark Kelly's), but will try
  // another way (older, maybe less complicated?).
  $final_string = substr($string_out,0,strrpos($string_out,,) - 1);
  $final_string .=.
  substr($string_out,strrpos($string_out,,) + 1);
  }
  
 
  So all you need is to modal your data around this, and you should be
  fine.
  You could construct your arrays then as follows as an example:
 
  
  $my_titles = array(title1,title2);
  $my_authors[title1] = array(a someone,a notherone);
  $my_authors[title2] = array(mr. a,mr. b);
  ...
 
  and so forth...how you construct the data is then very important as
  you can
  then later use it simplify your coding as you progress and as
 demonstrated
  below:
 
  In future, where the need justifies it, you can construct your array to
  already contain the needed string you want to output, it may help, but
 you
  will sometimes have the same effort in constructing the data for the
  arrays,
  so it is up to you to decide which approach is going to be best: e.g.
  $my_titles = array(title1,title2);
  $my_authors[title1] = array(a someone, a notherone  Mr. X);
 
  Then you can simply echo the array value:
  echo $my_authors[title1] . br;
 
  Hope it is enough info for to work on for now!!
 
  Have fun!
  Leon

You need to explain a bit more of what you are trying to achieve. There
are no limits I know of with using foreach to output content.

RE: [PHP] What to use?

Correct me if I'm wrong please, but I think number_format() has the
adverse effect of changing the value type from numeric to char and
therefore baring you from using it in mathematical equation later in the
script.

Anyway that's what it seemed to do to me when I used it on results from
a MySQL query...

That shouldn't happen. PHP is a typeless language and so type
conversions are juggled on the fly. If you pass a numerical string to a
mathematical operator, then the string will be converted to the
appropriate value.

If you get a result of 1,234.56 from number_format() and try to use that
as a numerical value (i.e. it's converted to an int or float), you'll end up
with the value being 1, though. Everything after the first non-numeric
character is lost. That's what he's talking about.

You're correct (kind of). The _result_ of number_format() is a string, but
it doesn't change the original number (unless you're assigning it back to
itself). Even if you are, that's why you use it after you've done all of
your math calculations and only when you're ready to display the number.

If it's really an issue, you can alwasy use printf() or sprintf() to solve
this problem, too.

Why not keep the precision internally and only deal with it as an output
formatting issue when you display the results?

$a = 5.;
