Codeigniter datatables query not working? - php

I am using codeigniter 2.0 version. In datatables query not working using datatable method. But when i run this in mysql means it is perfectly working. I dont know how to solve this issue. Below i have given my query,
$this->load->library('datatables');
$this->datatables->query("select sales.id as id, sales.date as date, sales.customer_name, sale_items.product_name as pname, sales.depositcard_amt as debit, 0 as credit from sales join sale_items on sale_items.sale_id=sales.id where sales.customer_id = $user and sales.branch_id=$branchid and sales.depositcard_amt != 0.00 group by sales.id UNION ALL select deposit.id as id, deposit.credit_on as date, deposit_details.customer_name, deposit_details.package_name as pname, 0 as debit, deposit.total_amount as credit from deposit join deposit_details on deposit_details.deposit_id=deposit.id where deposit.customers=$user");
$this->datatables->add_column("Actions",
"<center></center>", "id")
->unset_column('id');
echo $this->datatables->generate();
Please give any ideas to solve this. Thanks in advance.

Issue with logic in PHP palindrome challenge

As part of an interview I was challenged with debugging the following php script. I will first provide the original broken code. Then what I did to debug it followed with my attempt to fix the logic.
<?php

if ($this->string === 'exit') {
echo "Goodbye!";
exit;

break;
}
}
($palindromeFound) ? $palindromes[] = $palindromeFound: null
}
return $palindroms;
}
}
$class = new Palindrome();
$class->handle();
In addition to fixing some typos I updated the value on line 76 to 1, and line 80 to true. The code runs without error but thinks everything is a palindrome.

PHP finding the shortest path in 2D maze-like array

I am working on a 2D string with \n new line at the end.
The maze is 1000 x 1000 but I downscales this to 10 x 5 for the sake of readability.
0 means empty space.
S means starting point.
T means target point.
I created a function called cal_path to calculate the path between S and T. However the
result is not correct. I've hard-coded an estimate answer. Any advice/help would be much appreciated.
<?php
$maze='S000000000
0000000000
0000000000
00000000T0
0000000000';
$maze_y=explode(PHP_EOL,$maze);//convert line to array
function show_maze($maze_y){
for ($y=0;$y<count($maze_y);$y++){
for ($x=0;$x<=strlen($maze_y[$y]);$x++){
echo $maze_y[$y][$x];
}
echo "\n";
}
}
function cal_path($maze_y){
// I hardcoded it right now, I am stuck here
return array(
array(1,1),
array(1,2),
array(1,3),
array(2,4),
array(2,5),
array(2,6),
array(3,7),
array(3,8),
);
}
show_maze($maze_y); //original maze
$path=cal_path($maze_y);
foreach ($path as $point){
$maze_y[$point[0]][$point[1]]='P';
}
show_maze($maze_y);
Output:
S000000000
0000000000
0000000000
00000000T0
0000000000
Estimate Output:
S000000000
0PPP000000
0000PPP000
0000000PP0
0000000000
Here's my attempt, but it fails to find a shortest path.
<?php

You can use the following as a starting point.
It's a simple implementation of the pseudocode at: https://en.wikipedia.org/wiki/Dijkstra%27s_algorithm#Using_a_priority_queue
<?php
require_once 'src/MinQueue.php';
require_once 'src/Dijkstra.php';
require_once 'src/Maze.php';
$maze = Maze::fromString(file_get_contents('maze.txt')); // < a simple text file
$start = $maze->find('S');
$goal = $maze->find('T');
$helper = new Dijkstra(
// return neighbors
function ($a) use ($maze) {
return $maze->getNeighbors($a, ['W']);
},
// calculate the distance
function ($a, $b) use ($maze) {
return $maze->getDistance($a, $b);
}
);
$tStart = microtime(true);
$path = $helper->findPath($start, $goal);
$tEnd = microtime(true);
// export the maze with the path marked with '.'
$mazeStrWithPath = $maze->toString(function ($tile) use ($path) {
return in_array($tile, $path, true) && !in_array($tile->value, ['S', 'T'])
? '.'
: $tile->value
;
});
printf("%s\nin: %.5fs\n\n", $mazeStrWithPath, $tEnd - $tStart);
example output:

** Expected behavour **
My module should override the Magento Topmenu module whilst inheriting it allowing me to change the output markup
The problem
After running setup:upgrade and recompiling, I am just presented with the following error:
Fatal error: Call to a member function setOutermostClass() on null in /var/www/myecom.co.uk/app/code/Ecommerce/Topmenu/Plugin/Topmenu.php on line 36
It's like my code is not correctly extending the Topmenu block.
Any ideas?
For fix this my solution is insert construct as below:
public function __construct(Template\Context $context, NodeFactory $nodeFactory, TreeFactory $treeFactory, array $data = [])
{
parent::__construct($context, $nodeFactory, $treeFactory, $data);
$this->nodeFactory = $nodeFactory;
$this->treeFactory = $treeFactory;
}
This problem is a result of a recent Magento update which explains why I was having this problem using code that had previously worked for me on earlier Magento versions.
Final Solution
The final solution to fix this after Magento's update is to replace $this->_menu with $this->getMenu()
Now the working version of my custom module extends the Magento top menu class and just overrides the _getHtml function to change the markup as required.

Fatal error: Cannot redeclare fputcsv()

I have found a php inventory http://inventory-management.org/ easy but was written in PHP4? and I run now on PHP5. I have found some errors that I have already managed to fix but they are keep coming up so I would like to see if I can managed to run at the end. (As it is really simple script only has 5-7 php files).
Could someone help me please how to fix this error?

many thanks in advance
fputcsv() is a built in PHP function. This means you cannot name your own function the same thing.
If you need this code to work with PHP4, just check to see if the function exists first, then if not, create your own.
if (!function_exists('fputcsv')) {
// Your definition here
}

How to find bounced or undelivered mail id using PHP

I am sending a mail using PHP Mail Function
I just need to find the status of the mail whether it is delivered or Bounced
is there any possible way to solve this Problem
You can use return-path header with specific e-mail address - for example bounce#domain.com
After that all bounced (undelivered) e-mails would be returned to inbox for bounce#domain.com
You can connect to this pop3 inbox via PHP and read all messages.
Parse every messages and find (may be via regex) error code and reason...
I use this code:
$bounce = new BounceMail();
$bounce->setDebug(false);
//create connection
$bounce->createConnection('server', 110, 'user', 'password');
//parse messages
$bounce->parseMessages();
//save parsed messages to database
$messages = $bounce->getParsedMessages();
foreach ($messages as $message_id => $message) {
/* variable $message looks like:
$message = array(
'email_address' => 'email',
'bounce_type' => 'bounce type',
'smtp_server' => 'smtp_server',
'smtp_error' => 'smtp_error',
);
*/
//save returned email to database here
}
and BounceMail class:
<?php
/*
