The title is kind of misleading. I can't really explain in words what I'm looking for so I'll give some examples.

Here is a print out of my array:

array ( [0] => 9 [1] => 7 [2] => 3 [3] => 1 )

What I need to turn that into is:

1
13
137
1379

Now the array is dynamically generated and may be longer or shorter in number of keys/values.

Here would be another example:

array ( [0] => 8 [1] => 6 [2] => 1 )

would need to be
1
16
168

I'm sure their is a simple loop or something but I've been trying to do this for a half an hour now and just can't get it. Any help would be appreciated.

the end result can be in multiple arrays or strings or just an echo of each....

Thanks,
Rob

p.s. I apologize for just flat out asking for someone to write me code, but in my defense this is the first time I've ever posted a question and not an answer. Thanks in advance.

first point, as I see here, you need to reverse the order of your arrays.
To do so, use array_reverse() [ http://www.php.net/manual/en/function.array-reverse.php ]

PHP Code:

$ary=array(8,6,1);
$ary=array_reverse($ary);
print_r($ary)
/*should output
array( [0]=> 1 [1]=>6 [2]=>8 )
*/ 


And now, to concatenate everything, use a simple foreach loop:
http://www.php.net/manual/en/control...es.foreach.php

PHP Code:

$output=null;
foreach($ary as $key=>$value){
  $output.=$value;  //Add $value to $output for each iterations over the array
  /*
  To display the value with each number added one after the other.
  I have to admit I don't see the logic in that one, but it's your need...
  */
  echo $output;
} 


Thanks Tripy,

I've already tried something similar to this already.

//Your code outputs
116168

//Which is what I want (sortof) but I need it like so
1 16 168
or
1
16
168

There needs to be a break, space or some sort of delimiter. Thats where I'm running into the problem.

I've tried:

PHP Code:

$ary=array(8,6,1);
$ary=array_reverse($ary);
$output=null;
foreach($ary as $key=>$value){
       $output.="|".$value;
       echo $output;
} 


Which yields:
|1|1|6|1|6|8
But I would need something more like:
1|16|168
OR: returning an array is fine also. ie. ( [0] => 1 [1] => 16 [2] => 168 )

and

PHP Code:

$ary=array(8,6,1);
$ary=array_reverse($ary);
$output=null;
foreach($ary as $key=>$value){
       $output.=$value."<br />";
       echo $output;
} 


Which yields:
1
1
6
1
6
8
But I would need something like:
1
16
168
OR: returning an array. ie. ( [0] => 1 [1] => 16 [2] => 168 )

Nevermind.

I got it:

PHP Code:

$ary=array(8,6,1);
$ary=array_reverse($ary);
foreach($ary as $key=>$value){
$temp.=$value;
$output[$key]=$temp;
}  

print_r($output); 


Gives me:
Array ( [0] => 1 [1] => 16 [2] => 168 )

Just a bit of an optimization:

PHP Code:

<?php
$my_array = array(9,7,3,1);

$output_string = '';
for ($counter=count($my_array)-1;$counter > -1; $counter--) {
  $output_string .= $my_array[$counter];
  echo $output_string.'<br />';
}
?>

No real need for the array_reverse.

True...
I admit that I never needed array_reverse() in almost 10 years, but so for the negative for loop.
Which I completely forgot about...

Thanks Mr. Miller. Thats it exactly. I was going for a loop originally (if you read the end of my first post) but I went in another direction and got lost. This is perfect. Thank you.

array_reverse is something I've had to use; for example, when I use a string as the key and need to flip it over. It's rare, however, that I have to use it too.

Glad the code helped.
