[PHP] Looping problem?
require 'database.php';

$sql_subs = mysql_query(SELECT * FROM $t_02,$db)or
die(mysql_error()); while(list($id,$sub,$msk,$dns01,$dns02,$rtrs,$rnge)

$num = mysql_num_rows($sql_subs);
for($z = 0; $z $num; $z++) {
$vlans[] = subnet $subbrnetmask $msk {broption domain-name-servers
$dns01, $dns02;broption routers $rtrs;brrange $rnge;br}br; }
}
// Write everything out formated...
echo $vlans[$z]br /\n;
Right now it only pulling the last record???

You are only echo'ing the last record, $vlanz[$z]. You will need to loop
over $vlans again or put the echo line inside the for loop.

RE: [PHP] Looping problem?
This is probably more like what you need.
I can't see why you'd need to loop through your results using two different
methods (while and for)
require 'database.php';
$t_02 = subnets;
$sql_subs = mysql_query(SELECT * FROM $t_02,$db) or die(mysql_error());
$num = mysql_num_rows($sql_subs);
for ($z = 0; $z $num; $z++)
{
list($id, $sub, $msk, $dns01, $dns02, $rtrs, $rnge) =
mysql_fetch_array($sql_subs);
$vlans[] = subnet $subbrnetmask $msk {broption domain-name-servers
$dns01, $dns02;broption routers $rtrs;brrange $rnge;br}br;
}
// Write everything out formated...
for ($z = 0; $z $num; $z++)
echo $vlans[$z]br /\n;

No need to calculate the number of rows:
?php
require 'database.php';
$t_02 = subnets;
$sql_subs = mysql_query(SELECT * FROM $t_02,$db)
or die(mysql_error());
while (list($id, $sub, $msk, $dns01, $dns02, $rtrs, $rnge) =
mysql_fetch_array($sql_subs)) {
$tmp = subnet $subbrnetmask $msk {broption domain-name-servers
$dns01, $dns02;broption routers $rtrs;brrange $rnge;br}br;
print $tmp;
$vlans[] = $tmp;
}
?
I would recommend not simply doing a select *, but rather specifying
which columns you want. That way, if your database schema changes
(e.g., you add two more columns), your code won't break.

That way, if your database schema changes (e.g., you add two more columns), your code won't break. And, responding to myself, specifying your columns is also good practice because MySQL makes no guarantees about the order that columns are returned when you say SELECT *. Today, it may well be the order that you specified when you created your table. With the next upgrade, it may be alphabetical order, or by column type, or some other order that the software chooses. If you specify column names in your SELECT statement, you don't need to worry about it. This is especially important when you are using list() to assign variables based on their position in your fetched array. joel -- [ joel boonstra | gospelcom.net ] -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] looping problem?
Problem with looping over a CSV file (3 results for each line)? Here is
the CSV file contents...
MTPC-01,00:02:B3:A2:9D:ED,155.97.15.11
MTPC-02,00:02:B3:A2:B6:F4,155.97.15.12
MTPC-03,00:02:B3:A2:A1:A7,155.97.15.13
MTPC-04,00:02:B3:A2:07:F2,155.97.15.14
MTPC-05,00:02:B3:A2:B8:4D,155.97.15.15
Here is the script...
?php
$row = 1;
$file = fa.csv;
$id = fopen($file,r);
while($data = fgetcsv($id,100,,)) {
$num = count($data);
$row++;
for($c = 0; $c $num; $c++) {
echo host $data[0] {br /\nhardware ethernet $data[1];br
/\nfixed-address $data[2];br /\n}br /\n; }
}
fclose($id);
?
And this is the output...
(notice 3 results for the first line in the CSV file)
host MTPC-01 {
hardware ethernet 00:02:B3:A2:9D:ED;
fixed-address 155.97.15.11;
}
host MTPC-01 {
hardware ethernet 00:02:B3:A2:9D:ED;
fixed-address 155.97.15.11;
}
host MTPC-01 {
hardware ethernet 00:02:B3:A2:9D:ED;
fixed-address 155.97.15.11;
}
Any help is appreciated...

Remove the for-loop on the 8th line.

Re: [PHP] looping problem?
Shorter version of the script:
?
$line = file(fa.csv);
for($i=0;$icount($line);$i++){
$data = explode(,, $line[$i]);
echo host $data[0] {br /\nhardware ethernet $data[1];br
/\nfixed-address $data[2];br /\n}br /\n;
}
?
