PHP - Need Some Help With Php Object Code !!

I am trying to get elements in a dom object to display and manipulate however i cant seem to get them all out:

This is the feed:
<TransactionList>
 <TransactionID>507821041</TransactionID>
 <TransactionDate>2012-03-12T13:23:00+00:00</TransactionDate>
 <MerchantID>547</MerchantID>
 <MerchantName>The High Street Web</MerchantName>
 <ProgrammeID>1865</ProgrammeID>
 <ProgrammeName>THE HIGHSTREET WEB</ProgrammeName>
 <TrackingReference>{CLICKID}</TrackingReference>
 <IPAddress>82.34.245.167   </IPAddress>
 <SaleValue>0.0000</SaleValue>
 <SaleCommission>0.0400</SaleCommission> <LeadCommission>0.0000</LeadCommission>
</TransactionList>

However i am trying to get more than 1 tag but i cant seem to get it right.
This is my code:

<?php

$dom = new DomDocument;
$dom -> load ( "http://xyz.com" );
$tracking = $dom -> getElementsByTagName( "TrackingReference" );
//$com = $dom -> getElementsByTagName( "SaleCommission" );
$c1 = 0;
foreach( $tracking as $code )
   {
   #echo $code -> textContent.'<br>';
   $tcode = $code -> textContent;
   $tcom = $com -> textContent;
   //$com = $dom -> getElementsByTagName( "SaleCommission" );
   if ($tcode !="")
      {
      $remove_it = '{CLICKID}';
      $tcode = str_replace($remove_it, "", $tcode);
      echo $tcode.' VALUE '. $com .'<br>';
      $c1 ++;
      }
   }
echo 'Total Count: '.$c1;
?>

Please can someone help and tell me where im going wrong!

ok that works fine can i store a object tag in the db and show that same obj tag in the div

ill paste my code but its hard coded

<div id="resultmedia">
                                  <object width="640" height="385">

Hi

I have a login script which goes at the top of several pages in my site.  It works fine but I am trying to save some coding and re-writing out my script at the top of each of the pages.  Instead I have made a page called login.php and put all of the code for the script in there. 

Looks like this....
<?php
//login script 
if(isset($_POST['log'])) {
$emaillog = stripslashes($_POST['emaillog']);
$passwordlog = stripslashes($_POST['passwordlog']);
$emaillog = mysql_real_escape_string($_POST['emaillog']);   
$passwordmd5 = md5($passwordlog);  
//generate random session id which i want to follow the user round the site!
$CheckUser = "SELECT * FROM members WHERE email='".$emaillog."' AND password='".$passwordmd5."'";
$userDetails2 = mysql_query($CheckUser);
$userInfo = mysql_fetch_array($userDetails2);
$count = mysql_num_rows($userDetails2);
 if($count != 0) {
  $_SESSION['memberID'] = $userInfo['memberID'];
$_SESSION['accesslevel']= $userInfo['accesslevel'];
$_SESSION['email']= $userInfo['email'];

//add an id that will be carried throughout the user until the session is destroyed
 function getUniqueCode2($length2 = "")
 { $code2 = md5(uniqid(rand(), true));
if ($length2 != "") return substr($code2, 0, $length2);
else return $code2; }

$randomKey = getUniqueCode2(25);
$_SESSION['key'] = $randomKey;

//the user must have an access level of 2, before they can login
if($_SESSION['accesslevel']=='2')
$url = "loggedin/index.php";        
header("Location: ".$url."");   
$success = '1';
}
else {
$success = '0';
$logged = "incorrect login details" or die(mysql_error());
}

//now we need to update the login table to reflect a login
if($success =='1'){
$time = date("Y-m-d h:m:s");
$qupdate_mem_logins = "INSERT INTO logindetails (`email`,`time`) VALUES ('".$emaillog."','".$time."')";
 $rupdate_mem_logs = mysql_query($qupdate_mem_logins) or die(mysql_error());

        ?>

Now on the index page how do I reffer to this login script when someone fills in the form  At the minute I have the following code but it is not checking or running anything.

<?php
//login script 
if(isset($_POST['log'])) {
include('login.php');
}
}
?>

I've been trying to solve this issue for so long now.. I believe I'm close, but it's just the last part that I can't figure out how to solve..

I have a set of parsers and a controller. each parser is in it's own object named like Parsers_Imdb_Imdb.. What I want now is to be able to do this

Code: [Select]
$parse = new Parsers;
$imdb = $parse->Imdb->get_info('some random info');
So far I've managed to get into the Imdb parser object, but I 'm not able to grab the method.

parsers.php
Code: [Select]
class Parsers
{
function __construct() {

}

public function Imdb()
{
new Parsers_Imdb_Imdb;
}
}
imdb.php
Code: [Select]
class Parsers_Imdb_Imdb extends Parsers
{

function __construct()
{
parent::__construct();
}

public function get_info()
{
echo "get_info()";
}

}
I've got a __autoload() to solve the class declaration..

Could anyone please help me out with this?

Thanks in advance

Hi all, I have a script which I coded not long ago which works fine but there is one error which says:

Notice: Trying to get property of non-object in /home/www/***-*****.com/hts.php on line 374

I carnt see why its showing the error.


$fetch2=mysql_query("SELECT crew FROM users WHERE username='$username'") or die  (mysql_error());
$fetch1 = mysql_fetch_object($fetch2);

$crewrep1=mysql_query("SELECT * FROM crews WHERE name='$fetch1->crew'") or die (mysql_error());
$crewrep = mysql_fetch_object($crewrep1);

$result =  $rep + $reps;

$result55 =  $crewrep->rep + $reps; // Line 374


Can anyone else see why its showing the error?

Thanks for your help.

Hello, I have some questions here on PHP Object-Oriented.

I started learning PHP Procedural since some months, and I am doing quite well. I want to start with PHP Object-Oriented now, but the problems, I have not found a good easy readable tutorial on it. I have watched some videos on YouTube, but the way they explained it made me confused. I want to know something from you, if you are an experienced PHP programmer. I want to work on CMS like Drupal, WordPress, Magento  and Prestashop because I have noticed a rise in job availability in these fields in my country.

1/ Is it necessary to know PHP Object-Oriented to work as Drupal, Magento or Prestashop developers? (Note: I have a blog on WordPress, and I have huge experienced on the Dashboard, configurations and so on...)

2/ Can I start learning frameworks like CodeIgniter without learning PHP Object-Oriented?

Thank you.. Perhaps the questions may have not sense for you, but I just want to know your opinions. Please, if you are an experienced programmer, you reply me.

Hello. I have an object like this:

object->object_id
object->object_name
object->object_number

I have an array with many instances of the object, with different values. I want to sort that array to put first the object that the value of object->object_number is higher, and then descending. Please let me know if its not clear! thank you!

I thought I was deleting (unset) an object, but when adding a destructor, found it was never being fired.  I then used debug_zval_dump() and found that my refcount is 7, and it is my understanding that it must be 3 (more on why I think this later).

I searched where I might have left a copy, but couldn't find it.  Any recommendations how to do so?  I looked for ways to find all references to an object

https://www.php.net/manual/en/language.references.spot.php seems to be on topic, but doesn't say much? https://www.php.net/manual/en/features.gc.refcounting-basics.php seems to imply that xdebug_debug_zval() might help, but I haven't installed http://xdebug.org/ and haven't tested yet. https://stackoverflow.com/questions/2893672/is-there-any-way-to-access-all-references-to-given-object doesn't say much

After manually searching and not finding exactly what I was looking for, I came across this script.

    public function addGatewayClient(GatewayClient $client):TimerInterface
    {
        return $this->loop->addPeriodicTimer($this->period, function() use($client) {
            // bla bla bla
        });
    }

To verify whether a reference was being created, I wrote the below script.

<?php
ini_set('display_errors', 1);

class MyClass
{
    public function __destruct()
    {
        echo('__destruct'.PHP_EOL);
    }    
}

function getZval($v):string {
        ob_start();
        debug_zval_dump($v);
        $rs = ob_get_clean();
        return str_replace(PHP_EOL, '', $rs);
}

$obj = new MyClass;
echo('create object: '.getZval($obj).PHP_EOL);
$objC1 = $obj;
echo('save first reference: '.getZval($obj).PHP_EOL);
$objC2 = $obj;
echo('save second reference: '.getZval($obj).PHP_EOL);

// This is the line to comment out
$func = function() use($obj) {};

echo('set function: '.getZval($obj).PHP_EOL);

unset($objC1);
echo('delete first reference: '.getZval($obj).PHP_EOL);

unset($objC2);
echo('delete second reference: '.getZval($obj).PHP_EOL);

unset($obj);

echo('Done'.PHP_EOL);

If I comment out \\$func = function() use($obj) {};, I see the refcount start at 3, go up to 5 and then back down to 3, then __destruct() being called, and then the script completion "Done".  But then when I don't comment the closure function, I see it go up to 6, go down to 4, the script completion "Done", and then __destruct() being called.

Guess I can just set the object to be deleted to NULL, but I feel there should be a better way.  Any recommendations?

On a side note, debug_zval_dump() is more difficult in the real world if there is recursion, and my getZval() function results in a fatal error by exhausting too much memory.  I also tried just calling debug_zval_dump(), but it definitely wasn't a good call.

I am passing an array in the following function and want my data to be added in the table .Here is the statement
Code: [Select]
public function insert_data($user_info)
 {
 try{
$dbh = new PDO("mysql:host=localhost;dbname=phpfaqproject",'root','');
//echo "connected";
}
catch(PDOException $e){
echo $e-> getMessage();
}
$sql ="INSERT INTO account (username, userpassword, email, role, location, interest, homepage)
       VALUES ('" .$user_info['username']."','".$user_info['password']
      ."','".$user_info['email']."', 'user','".$user_info['location']."','".$user_info['interests']
      ."','".$user_info['homepage']."')";
          echo $query."<br />";
          $stmt = $dbh->prepare($query);
       
          $stmt->execute();
}
I don't know why it is not updating the tble although echo $query gives correct results.

I've been getting this error message:

Trying to get property of non-object in /application/controllers/index.php on line 37

Here is line 37


$this->view->title =  $pageInfo[0]->title;

any help would be much appreciated.

I try to do this but it doesn't work:

How do you echo the values?

I'm curious if anyone has information on how much overhead there is with creating an object in PHP. I've tried finding some benchmarks but haven't really been able to find anything solid to use for reference. Also, when dealing with objects what optimizations can be done to improve performance.

I ask because my project I've been working on is entirely OO. Everything, including views, are objects (though their state and behaviour is really just the model they're representing and a show() function that has the HTML used to display the model). This makes development very easy and clean but I'm trying to figure out how much of a difference I can expect in production and in what ways I can limit any negative side effects. What things could be cached, and what things can't? For example, is it possible to cache the class definition without caching instances of that definition (since they'd be different from page view to pageview)? Would that be helpful.

Any pointers would be great. I haven't had a lot of time with performance tweaking so I'm not sure of any known pitfalls. I know objects and function calls use a bit more overhead but I've never found out how much more.

Thanks in advance. 

Suppose I am coding up a crating calculator.  A crate is a box with dimensions, weight, built of certain material, and having certain contents.   The crating calculator I am writing is one that computes dimensions of the box, once given dimensions of variou contents put into it. Right now I have a factory that figures out which contents object to create, in order to figure out contents dimensions.   Something like

class CrateDimensionFactory 
{
    function getDimensionAwareClass(array $options)
    {
        return $dimensionAwareObject;
    }
}

//later in some code:
$dimensionAwareObject->getDimensions();

Now, I want to also put in the weight of crate which is the sum of contents of crate plus the weight of the crate. Question ... do I stick the weight computations into the same factory?  i.e.

class CrateFactory 
{
    function getDimensionAwareClass(array $options)
    {
        return $dimensionAwareObject;
    }

    function getWeightAwareClass(array $options)
    {
        return $weightAwareObject;
    }
}

//later in some code:
$dimensionAwareObject= (new CrateFactory())->getDimensionAwareClass($options);
$dimensionAwareObject->getDimensions();

$weightAwareObject= (new CrateFactory())->getWeightAwareClass($options);
$weightAwareObject->getWeight();

I can even stick the weight into the same returned object, where I create a single object from Factory, and then just call

$crateAwareObject= (new CrateFactory())->getCrateAwareClass($options);
$crateAwareObject->getDimensions();
$crateAwareObject->getWeight();

There are many ways to do it .. I guess.  But the spirit of my question is -- should I, do I put dimensions and weights together or separately, and how exactly do I separate them or how exactly do I put them together, with regards to how SRP is concerned?

Currently, I'm trying to create an OpenGL project which creates a visual for data in a file for an assignment, for example, a pie chart. While I have this pie chart correctly and accurately displaying the data, another part of the assignment is being able to zoom in and move the object, of which I have no idea where to start.   This is the code for the pie chart.

bool OGLPieChart::MouseLBUp( int x, int y )
{
	return true;
}
bool OGLPieChart::MouseLBDown( int x, int y )
{
	return true;
}

And it produces this result:   Unfortunately, a constraint for this assignment is that we cannot use GLUT, it is an optional constraint but it would lose me 8% should I use it.   Any help with zooming and panning it would be extremely appreciated.
