#11821 — array search part 2

I am attempting to search the array for matching entries.
All matches, not just the first.
While the code works fine, the result is not what I want.
$btrack should return the value of six0[$track][0].
Instead, the result shows the array key number.
Even if I change the [0] to [1].
Why?

<?php

$track=$_GET['item'];
echo $track;

$flip=$six0[$track][1];
echo $flip;
echo "<br>";

$max=count($six0);

$arow=0;

while ($max>$arow){

$btrack=$six0[$arow][0];
if ($btrack=$track){echo $btrack;}
$arow++;
}


?>

Result example.

You may consider using a "linter".

I changed $btrack to $bsong and still got the same result.
= or == made no difference.

I realized I was searching for the wrong item.
That is why $track was producing the number instead of the string.
Now it works a little better.

For the 17 billionth time, you thick dope, you have used = instead of ==

You thicker DOPE! IT MAKES NO FRICKIN DIFFERENCE!
And the examples I have seen at php.net all use a single =.

Generally, there is a big difference between an assignment (=) and a
equality comparison (==).  A programmer should know, when to use which.

It only doesn't make a difference when some other problem when some
other problem is *also* chewing on your butt. Just because it doesn't
yell "+++ OUT OF CHEESE ERROR % REDO FROM START" doesn't mean its
not a problem.

Yes, it does. The reason that it *appears* to you that it doesn't is that in this case, you have 
*another* error in addition to this one, which prevents your code from working until you have 
corrected *both* errors.

> And the examples I have seen at php.net all use a single =.

Post the URLs of a couple of these examples.

A bit of an exaggeration, Tim.  It's only been 16,364,196,273 times. :)

?>

This method works, but stops searching when a match has been found.
Is there a way to continue the search when a match has been found?
There are times when songs are liste 2 or more times and with different
artists. So I need to find them all and then recover the one that matches
to the original track.

It dosen't stop after finding one match, you have only one match.
Please indent your code better, makes it easier to read and a lot easier 
for you to spot errors.

Objection m'lud. He couldn't spot an error in his code if it had a 
flashing neon sign pointing at it.

#11848 — solved (was: array search part 2)

<?php

$track=$_GET['item'];


$asong=$six0[$track][0];
$flip=$six0[$track][1];

$max=count($six0);

$match=0;

for ($item=0;$item<=$max;$item++){
if ($flip==$six0[$item]['0'])
  {if ($six0[$item][2]=$six0[$track][2])
   {$match=$item;}}
}

http://mroldies.net/list/decade60.html

The for loop searches through the array for a match first based on name.
Then further matches by label number.
[0]=charted name
[1]=flipside
[2]=label

There's no need to assign something to itself just to test it.  The
test:

  if ($six0[$item][2]) ...

is probably what you want, though the assignment will create
$six0[$item][2] if it does not already exist, so the two are not exactly
the same.

You can make the code more self-documenting by using defined constants
for these indexes:

  define('FLIPSIDE', 1);
  define('LABEL',    2);
  ...
  if ($six0[$item][LABEL]) ...

or by using string indexes directly (e.g. if ($six0[$item]['label']) ...).

Hello Ben.

Most around here are still trying to get Richard to understand and 
implement the difference between 'assignment' and 'comparison'.

Now you are bringing in another level of discipline.

The next thing you will be asking is for him to proof read his code when 
he has errors prior to bringing them here.

But I have to admit it does give me some humorous light reading at times.

I try not to post to the poster if you see what I mean.  The post
reminded me of a way to make things clearer, and I fondly hope that it
might help others who just lurk here, or who see these things in search
results.

Agreed.  I was just being facetious.
