Rails - Oct 2005 - Maybe stupid: for statement

hey

i want to have a for statement in rails
that can count the size of an array and use that number to get it values


for( $j = 1; $j < count($beschrijving); $j++)
{
      $beschrijvingTekst = $beschrijving[$j];
}

i have somehting like this for creating tables in fpdf

#Kolom koppen
@header =
[''Employee'',''Location'',''Duration'',''Start'',''Stop'']
#Kolom breedtes
@w=[50,50,40,40,40]
#Kolomkoppen afprinten


for head in @header
   pdf.Cell(@w[head],h, @head, 1,0,''C'')
end

i need the have the position of array header (head) to get the values out of 
array w

Try one of the following (assuming I''m understanding what you want):

# In the block head will be an element of @header, idx will be its index
@header.each_with_index { |head, idx| pdf.Cell(@w[idx], h, head, 1, 0, 
''C'') }

Or

# In the block head will be, e.g., [50, ''Employee'']
@w.zip(@header).each { |head| pdf.Cell(head[0], h, head[1], 1, 0,
''C'') }

This is actually a Ruby question, not a Rails question, but the answer 
is, use an itterator, you could use a $beschrijving.each or a 
$beschrijving.count.times .
