[SOLVED] Looping question: Creating a tale from an array

[JPark]

I can't figure out the loop logic on this one and would appreciate your help.

 

Say I have an array:

$test = array("first => this one", "second => that one", "third => the other one", ... "twentiest => the other other one");

 

And I want php to automatically generate a table that is 5 columns wide and 4 rows tall, populating it with the array items, how do I do it?

 

I can get all rows or all columns but not all of both.

 

Help?  Please and thank you.

I don't know if you can get what you want from this.  This does 4 columns until it reaches the end

define ("NUMCOLS",4);

$res = mysql_query("SELECT id,thumb,cat FROM image WHERE cat='events'");

$count = 0;

echo "<table>";
while (list($id,$thumb,$cat) = mysql_fetch_row($res)) {

    if ($count % NUMCOLS == 0) echo "<tr>\n";  # new row
    echo "<td>stuff in here</td>\n";
    $count++;
    $counter++;

    if ($count % NUMCOLS == 0) echo "</tr>\n";  # end row
}

# end row if not already ended

if ($count % NUMCOLS != 0) {
   while ($count++ % NUMCOLS) echo "<td> </td>";
   echo "</tr>\n";
}
echo "</table>";

try

<?php
$test = range(1,20);
$test = array_chunk($test, 5);
echo "<table>\n";
foreach ($test as $line) echo "<tr>\n\t<td>", implode("</td>\n\t<td>", $line), "</td>\n</tr>\n";
echo "</table>\n";
?>

But what if I wanted to use my array statement instead of querying the database?

 

$test = array("first => this one", "second => that one", "third => the other one", ... "twentiest => the other other one");

instead of

$res = mysql_query("SELECT id,thumb,cat FROM image WHERE cat='events'");

try

<?php
$test = range(1,20);
$test = array_chunk($test, 5);
echo "<table>\n";
foreach ($test as $line) echo "<tr>\n\t<td>", implode("</td>\n\t<td>", $line), "</td>\n</tr>\n";
echo "</table>\n";
?>

 

Sasa, NICE!  One question... where/how would I specify MY array

 

$myarray = array("first => this one", "second => that one", "third => the other one", ... "twentiest => the other other one");

change line

$test = range(1,20);

to

$test = $myarray;

Much thanks!
