foreach -- puttin each result in its own variable

[johnwayne77]

i am trying to make a currency converter script.

i fetch the rss data from a daily updated currency source.

I can echo as many currencies as I want but I don't know how to put each in its own variable (so I can use it for conversion in another script).

[code]
$items = array_slice($rss->items, 0, 2);
foreach ($items as $item )

{
  echo '
  <div align="center">&nbsp;&nbsp;
  <div align="center">1&nbsp;&nbsp;'.$item['title'].' &nbsp;&nbsp;=&nbsp;&nbsp; '.$item['description'].'&nbsp;RON<br />
  </div>
  <hr width="60%" />
 
</div>';
}[/code]

Now, I would like to do something like this:

$variable1 = $item['title'][0]
$variable2 = $item['description'][0]
$variable3 = $item['title'][1]
$variable4 = $item['description'][1]

do u have any ideas?

[johnwayne77]

if i do this:

[code]  $variable1 = $item['description'];
    $variable2 = $item['description'];
  $variable3 = $item['title'];
    $variable4 = $item['title'];

echo $variable1;
echo $variable2;
echo $variable3;
echo $variable4;[/code]

i get this:
[b]
2.63222.6322USDUSD
3.39983.3998EUREUR[/b]

it seems it doubles the result, i only need 1 result per variable so I can use it after that with other scripts

[johnwayne77]

I'm wondering... is there an echo like command to print only a specified numbers of characters from a string?

like if i have $variable1 = 123456789 , i want to echo only the first 5 digits (12345)

You already have the information in an array, so use the array instead of making more variables.

As for the answer to your other question, yes there are many functions to manipulate strings, read the section [url=http://www.php.net/strings]on strings[/url] in the manual.

how do I do that?

I need to be able to carry the results to other scripts also, that's why I thought about variables

[kenrbnsn]

What do you mean by "carry the results to other scripts"?

After I get the results (e.g. USD, EUR, 1.21, 1.45) ,which are the currencies and the rates, and I thought of carrying them like this: $var1 = USD, $var2, EUR and so on(. i don't know how to do that directly from arrays regarding my script.), I would use them in mathematical operations for a currency conversion script.

Am I clear enough with the explanation?

[johnwayne77]

so, any ideas how can I solve this issue? I would really appreciate the help

[johnwayne77]

how do I substitute foreach with a for syntax:

like instead of this code:

$items = array_slice($rss->items, 0, 2);
foreach ($items as $item )

i would need a new code to handle only the first two values like for $items = 1 do '...' and for $items = 2 do '...'

any ideas?

[kenrbnsn]

Please show us a dump of the array:
[code]<?php
echo '<pre>' . print_r($items,true) . '</pre>';
?>[/code]

this is it:

[b]Array
(
    [0] => Array
        (
            [title] => USD
            [link] => http://www.infovalutar.ro/2007/1/17/USD.bnr
            [description] => 2.6322
            [guid] => http://www.infovalutar.ro/azi/USD.bnr
            [summary] => 2.6322
        )

    [1] => Array
        (
            [title] => EUR
            [link] => http://www.infovalutar.ro/2007/1/17/EUR.bnr
            [description] => 3.3998
            [guid] => http://www.infovalutar.ro/azi/EUR.bnr
            [summary] => 3.3998
        )
