Programming :: Converting A PHP Array Into An HTML Array?

Aug 9, 2009

I'm writing a PHP program. I've encountered a problem; in the following code I try to pass $_POST['delete'] which is an array as the value of a hidden input to some form, but it doesn't do so.there's something wrong with converting PHP array into HTML array. I'm sure that $_POST['delete'] is not null and is a real array.

echo '<input type="hidden" name="delete[]" value="'.$_POST['delete'].'" />';

General :: Convert Full-disk RAID5 Array To Partition-based Array?

Dec 23, 2010

I have a RAID 5 array, md0, with three full-disk (non-partitioned) members, sdb, sdc, and sdd. My computer will hang during the AHCI BIOS if AHCI is enabled instead of IDE, if these drives are plugged in. I believe it may be because I'm using the whole disk, and the AHCI BIOS expects an MBR to be on the drive (I don't know why it would care).

Is there a way to convert the array to use members sdb1, sdc1 and sdd1, partitioned MBR with 0xFD RAID partitions?

Ubuntu Servers :: Creation Of RAID-0 Array In Disk Utility Resulting In Smaller Than Expected Array?

Sep 27, 2010

I have a NETGEAR ReadyNAS NV+ with four 1TB drives in a RAID-5 array. This is our primary file storage. This has previously been backed up to a hardware RAID-0 array directly attached to our Windows server. The capacity of this backup array is no longer sufficient. So the plan was, take a bunch of 200GB to 320GB drives (And a 750) I had kicking around, chuck them in a couple of old SCSI drive enclosures I have collecting dust, attach them via IDA/SATA-to-USB adaptors to a USB hub, attach that to the server, create a JBOD array spanning the disks, and back up the NAS to that. Performance is not an issue as this is just to be used for backup, with the idea being as near to zero cost as possible (Spend so far = NZ$100�ish).

The first hurdle I struck was Windows not supporting Dynamic Disks on USB drives (Required to create a spanned volume). At first I resisted using another machine (i.e. a machine running Ubuntu) as I didn't want to dedicate a piece of hardware to backing up the NAS. I then decided it would be acceptable to do this via a VM, which is what I've done.So I have 10.04 running under VMWare Server 2.0.2 under Windows Server 2008 R2. The disks are all presented to the VM. I wasn't sure if I was going to end up creating the array under LVM or something else, but I noticed Disk Utility has an option to create an array, so I tried that. When I add two 250GB drives, the array size is 500GB. When I then add a 160GB drive, the array size drops to 480GB. Huh? If I keep adding disks (Regardless of order) the final array size comes out at 1.8 TB, as per the attached screenshot. Now with the following drives, I expected something more like:

160 + 250 + 250+ 750 + 250 +200 + 200 + 250 + 320 + 250 + 320 = 3.2TB

Am I missing something or making a false assumption somewhere?

General :: Bash: Calculating In Array And Storing Result In Array?

Dec 2, 2010

I have an array called arrayini which stores numbers. I want to take log to the base 2 of each of the numbers in that array and put it in file called result. I've used the following code to do it.

Code:

size=${#arrayini[@]}
for ((i=0;i<size;i++))
do
echo "scale = 12; l(${arrayini[$i]})/l(2)" | bc -l
done >result

It works fine but its taking pretty long to calculate since I've got about 230,000 items in the array. So I decided to store the result into an array hoping that it'd be faster. I tried the following code. arrayresult is where I try and store the result. The code doesn't work because of the second last line.

Code:

unset arrayresult
size=${#arrayini[@]}
for ((i=0;i<size;i++))
do
arrayresult[$i]="scale = 12; l(${arrayini[$i]})/l(2)" | bc -l
done >FILE2

There is a syntax error clearly.

Programming :: Bash Array - More Than One Value Per Item?

Nov 28, 2010

Is it possible to have an array in Bash that can hold more than one value per item?

For example I would like an array like this:

Entry 1: apple, green
Entry 2: banana, yellow

And be able to call the fruit names and their colour in a list. Something like:

for fruit in "${array[@]}"
do
echo a $fruit is $colour
done

If that is possible, is there a limit to values per item? For example some entries in an array could be:

Entry 1: apple, green, round, pips, tree
Entry 2: banana, yellow, long, skin, tree

And I would like to pick out the values such as #3 being "round" and "long".

Programming :: Extract Values From Array PHP

Jul 2, 2009

The idea is to make a website to check the availability of domains and it works but its not pretty yet. Below is what i have till so far:

## this is the API from my domain registrar.
<?php $client = new SoapClient('http://api.sync.com/?wsdl');
## I have a search box that sends the request to this page
$var = $_GET ["s"];

## remove the most common subdomains from the request.
$var=eregi_replace("www.", "", $var);
$var=eregi_replace("mail.", "", $var);
$var=eregi_replace("ftp.", "", $var);
$var=eregi_replace("pop.", "", $var);
$var=eregi_replace("smtp.", "", $var);

## remove any TLD extension from the request.
$split = explode(".", $var);
$main = $split[0];
$arraysize = sizeof($split);
for ($x=1; $x<$arraysize; $x++) {
$tld .= "." . $split[$x];
}
## login to the API
$paramLogin = array('handle' => 'randall', 'password' => 'password');

## match the domain with any possible TLD
$varcom = $paramAvailDomain = array('sld' => $main, 'tld' => 'com');
$varnet = $paramAvailDomain = array('sld' => $main, 'tld' => 'net');
$varorg = $paramAvailDomain = array('sld' => $main, 'tld' => 'org');
$varbiz = $paramAvailDomain = array('sld' => $main, 'tld' => 'biz');
$varinfo = $paramAvailDomain = array('sld' => $main, 'tld' => 'info');
$vareu = $paramAvailDomain = array('sld' => $main, 'tld' => 'eu');
$varnl = $paramAvailDomain = array('sld' => $main, 'tld' => 'nl');
$varbe = $paramAvailDomain = array('sld' => $main, 'tld' => 'be');
$varde = $paramAvailDomain = array('sld' => $main, 'tld' => 'de');
$varcouk = $paramAvailDomain = array('sld' => $main, 'tld' => 'co.uk');
$varorguk = $paramAvailDomain = array('sld' => $main, 'tld' => 'org.uk');
$varname = $paramAvailDomain = array('sld' => $main, 'tld' => 'name');
$varmobi = $paramAvailDomain = array('sld' => $main, 'tld' => 'mobi');
$varin = $paramAvailDomain = array('sld' => $main, 'tld' => 'in');
$vartv = $paramAvailDomain = array('sld' => $main, 'tld' => 'tv');
$varcn = $paramAvailDomain = array('sld' => $main, 'tld' => 'cn');
$varws = $paramAvailDomain = array('sld' => $main, 'tld' => 'ws');
$varnu = $paramAvailDomain = array('sld' => $main, 'tld' => 'nu');
$varbz = $paramAvailDomain = array('sld' => $main, 'tld' => 'bz');
$varcc = $paramAvailDomain = array('sld' => $main, 'tld' => 'cc');

## this requests the domain.COM and domain.NET
$varcom;
$varnet;
?>
<div id="content">

## below prints the result
<?php
print "<html><body><pre>";
$result1 = $client->__soapCall('Login', $paramLogin);
echo "<b>Result Login:</b>
" . print_r($result1, true);

$result15 = $client->__soapCall('AvailabilityDomain', $varcom);
$resvarcom = var_dump($result15, true);
$result15 = $client->__soapCall('AvailabilityDomain', $varnet);
$resvarnet = var_dump($result15, true);

print "</pre></html>";
?>
<?php

## the returned array looks like this

Result Login:
Array
(
[code] => 200
[message] => Login succesful
)
array(3) {
["code"]=>
string(3) "200"
["message"]=>
string(20) "Domain not available"
["result"]=>
object(stdClass)#236 (1) {
["status"]=>
string(5) "TAKEN"
}
}
bool(true)
array(3) {
["code"]=>
string(3) "200"
["message"]=>
string(16) "Domain available"
["result"]=>
object(stdClass)#232 (1) {
["status"]=>
string(4) "FREE"
}
}
bool(true)
?>
## till so far it works

What I need to do is to make this ugly looking reply in to something more readable, basically if TAKEN print occupied and if free print its yours to grab. I have been struggling with the in_array function but i'm not getting anywhere close in getting it to work.

Programming :: How To Access Four Dimensional Array

May 23, 2010

I have never used multidimensional array for a long time so please consider this as a newbie question. I am editing a program that uses a 4 dimensional array and I think I'm losing track of the indexes.

day = 0 to 30
hour = 0 to 23
channel = 0 to 7
len = 0 to 63
unsigned char idx[day][channel][hour][len];

I have seen that the assignment to a string is
snprintf(idx[day][hour][channel], 64, "%s/%s", dayofmonth, hourofday);
Is this correct? Because when I access with a day argument, that day value goes into the hour part.
