Re: [PHP] need help with foreach
Its not very clear what you want to achieve with that code snippet.
If you are pulling database rows out of your database with
mysql_fetch_array(), then you do not need a foreach loop.
I think you may want something like this, but without knowing your
database table structure and the query you have used it is only a guess.
while($row = mysql_fetch_array($result2,MYSQL_ASSOC)){
echo a href=client.php?art=.$row['pix'].
border='0'{$row['jobType']}/a\n;
if($row['url']!='')echo html to use with .$row['url'];
}

I want to tell the server to do 2 things when I click on the jobType
link.
This is the code that I have now which displays the art when I click
on jobType
foreach($row as $jobType)
{
$row = mysql_fetch_array($result2,MYSQL_ASSOC);
echo a href=client.php?art=.$row['pix'].
border='0'{$row['jobType']}/a\n;
}
I now want to, with the same click, also show the url if I have a url
for that jobType in my database column called url.
Thank you for any help.

Re: [PHP] Run script every 30 seconds
Sorry, slight adjustment, make that $t=time()-31; in the first line so
that the script runs immediately.
You could run the script as a daemon. man daemon.
The sloppy way of running the script every 30 seconds would be to use
sleep(30), but that would cause the script to run at 30 seconds +
execution time.
If you make a loop like this you could get around that:
$t=time()+31;
while(true){
if(time()$t+30){
$t=time();
YourMainScriptFunction();
}
else usleep(1000); //adjust to how often you want to check
}

Re: [PHP] natsort()
natsort() places the array elements in natural order but not the keys.
If you want your elements printed using print in a loop either
reorganise the keys first or use foreach.
The easiest method would be to use:
foreach($dl as $filename){
print $filename;
}
If you insist on using a while loop you could use:
$dl = array_merge($dl); to reorder the keys from 0 to array size-1.
then use:
while ($i = $array_count){print $dl[$i]; $i++;}
If you use while you must increment $i to get all of the elements printed.
Alternatively you could use a for loop after reordering the keys:
for($i=0;$isizeof($dl);$i++){
print $dl[$i];
}

Hi
php5
code
$d = '/somedir/subdir';
$od = opendir($d);
if ($od) {
$dl = scandir($d);
natsort($dl);
}
/code
The sorted array is available through print_r().
How can I obtain a natsorted array that can be listed using :
while ($i = $array_count){print $dl[$i]}
Thanks
