[PHP] I only want x number of lines of data

2006-08-09 Thread Ross 
At the mometn I have this


function display_result($module_no) {

if ($module_no != ) {
$module_no =unserialize ($module_no);
foreach ($module_no as $number = $data) {

$count=$count+1;?

Q.?=$count; ?- span style=font-weight:bold?=$data;?/spanBR /
?
}
}

which outputs all the data in the array..typically..

Q.1- pass
Q.2- pass
Q.3- pass
Q.4- pass
Q.5- pass


but what if i only want q1-q3 output? any ideas how I can modify the script 
to give me x number of outputted answers?

why $count when you already have $number

 
 Q.?=$count; ?- span style=font-weight:bold?=$data;?/spanBR /
 ?
 }
 }

function display_result($module_no, $max = null)
{
if (is_string($module_no)  $module_no)
$module_no = unserialize($module_no); // god knows why your 
using this
if (!is_array($module_no)) return;

if (!$max || !is_int($max)) $max = count($module_no);

$count = 0;
foreach ($module_no as $number = $data) {
if ($count  $max) break;
echo Q., $count++,' - strong',$data,'/strongbr /';
}
}


PS - generally is better when function don't echo stuff... it makes them
more flexible.

 why $count when you already have $number

And even if you really want to use $count, why not use the faster +=
operator:

$count += 1;

Or if 1 is always going to be your increment:

$count++;

Or if you know how ++ works and want to eke just a tad more speed out:

++$count;

Cheers,
Rob.
