[PHP] Looping through array
Say I have an array containing ten items, and I want to display them in a table as follows: 5 4 3 2 1 10 9 8 7 6 What's the best way to loop through that array to do that? My thinking gets me to create a loop for 5 through 1, repeated twice, and the second time I add '5' to the index value.

Something like this perhaps...
$arr = array(...);
$per_row = 5;
$elem = count($arr);
for($i=0; $i$elem; $i++) {
if( $i == 0 )
echo tr;
if( $i % $per_row == 0 )
echo /trtr;
echo td$arr[$i]/td;
}

That simply displays things in order, 1 through 5, then 6 through 10.

Re: [PHP] Looping through array
If you know the array elements, you may not need to loop. Why not just echo the particular array elements i.e. td?php echo $array[2]; ?/td for example?
Re: [PHP] Looping through array
$arr = array(...);
$first_row = '';
$second_row = '';
for ($i=4; $i=0; $i--){
$first_row = $first_row . td{$arr[$x]}/td;
$second_row = $second_row . td{$arr[$x + 5]}/td;
}
print 'tr' . $first_row . '/tr';
print 'tr' . $second_row . '/tr';

Re: [PHP] Looping through array
So in other words, you have an array like $arr = array (1,2,3,4,5,6,7,8,9,10) but you want it to render on the page as: 5 4 3 2 1 10 9 8 7 6 right? -D On Nov 16, 2006, at 1:35 PM, Ashley M.

Ashley: Look into array_chunk() and array_flip(). The first can break your main array into two and the second can reverse the results. tedd -- --- http://sperling.com http://ancientstones.com http://earthstones.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

In order to figure out the best PHP logic to generate the series, I'd first make sure the markup is solid. I realize that you've already indicated a table markup in two rows, but I'd like to examine that. Can you tell us why the numbers are in this particular sequence? Do the numbers represent items that are conceptually in ascending order but are presented in reverse order on the screen? If so, I'd wonder whether someone reading the page with assistive technology might be confused by the reverse order, and I'd try to find a way to mark them up ascending and then change the sequence stylistically. Are they split into two rows because they represent two discrete groups in the data set or because of display considerations? If the latter, I'd argue that they don't really belong in two table rows; that using tables to force presentation is misapplying the tool. Have you considered an unordered list, floated right, wrapped in a container whose width naturally forces a wrap after the fifth item? I like that solution because it allows you to mark up the numbers in sequence and in future change the number of items in the sequence and/or change the way the series is presented visually without having to mess with the logic generating the markup.

[PHP] looping through array with list()/each()
OK so I've done this hundreds of times, but this time I cannot get it to
work.
Please cast an eye over the following code and output and tell me why $k and
$v are not being set:
Code:
-
$ser = array( 'first', 'second', 'third', 'fourth', 'fifth' );
reset($ser);
while ( list($key, $val) = each($ser) );
{
echo \$key = $key, \$val = $valbr;
}
-
Output:
--
$key = , $val =
--
I tried giving the $ser array numeric keys and string keys, both made no
difference.
thanks,
- Kev
