php array and $i variable

[CodilX]

this is the problem..

i have a huge array (imported from an xml file), and i'm trying to extract the info.

the problem is, that i have a for loop from 1 to 10, and i want the $i variable to be linked with the echo statement, but i can't get it to work.. in other words.. :

for($i=1;$i <= 10;$i++) {   
 echo $xml->content->numbered_content[b]$i[/b]->header; (of course this doesn't work, thus my problem)
}

array looks smth likes this:

content =>
 (
 [numbered_content[b]1[/b]] =>
 (
  header => bla
  content => bla
 )
 [numbered_content[b]2[/b]] =>
 (
  header => bla
  content => bla
 )
 [numbered_content[b]3[/b]] =>
 (
  header => bla
  content => bla
 )
 )

i hope someone understood my problem.. i just need to know how to include a variable in that echo statement. thank you!

Hi,

Try:

for($i=1;$i <= 10;$i++) {
  echo $xml->content->{'numbered_content' . $i}->header;
}

Hi there Codilx,

echo $xml->content->numbered_content$i->header; (of course this doesn't work, thus my problem)

Just reading this quickly, dont you just need to concatonate the vars?

echo $xml->content->numbered_content.$i.->header; (of course this doesn't work, thus my problem)

I'm not to sure on xml though but thats how I read the code. just thought I would make the suggestion... Then again you have more than likely tried this already...

Hi there codilx,

I'm curious now, what was the solution, as I'm not familiar with XML, but I intend to start..

Cheers,
