I created a function to convert PHP Object to Array.
The main function remove unnecessary data from the object.
Second loop gives you straight array. You can manipulate it as you want to display PHP Array data.

function phpObjectToArray($phpObject)
{
    if(!is_object($phpObject) && !is_array($phpObject))
        return $phpObject;

    $phpArray=array();
    foreach($phpObject as $member=>$data)
    {
        $phpArray[$member]=phpObjectToArray($data);

    }
    return $phpArray;
}

$scopeArray = phpObjectToArray($show_scope_data);

echo"
";
print_r($scopeArray);

Output after passing object.

)


$array_list = array();

foreach($scopeArray  as $key=>$value)
{
    $array_list[$key]= $scopeArray[$key]["data"];
}

print_r($array_list);

Last print_r() function will display normal array.
					

JSON objects are used everywhere and very easy to implement.
Thanks to PHP it has inbuilt function but if you want different kind of json object which is possible based on requirement. In my case i wanted to use
var availableTags = [{“key”:1,”value”:”AERO 1″},{“key”:2,”value”:”AERO 3″},{“key”:3,”value”:”AIR CANADA 4″},{“key”:6,”value”:”AIR CANADA 26″},{“key”:7,”value”:”AIR CANADA JAZZzzz”}];

if have key value pair of array json_encode($yourArray) will not return
above format!

Well that was my requirement, yours could be different but here is the solution.
You can tweak little bit and ready to go!

 $value)
{
   if(empty($key) && empty($value))
   {
	  continue;
    }
	$temAccNameArray[] = array('key' => $key,'value'=>$value);
}
echo json_encode($temAccNameArray);
?>;

I spend several day to figure our Paypal Recurring PayPro Flow Payment API.
But finally managed to create something cool with a class. I would like to share with you guys.

Why Paypal Recurring PayPro Flo ?
Companies want to charge there customers on monthly basics for different services that’s why its called Recurring. With PayPro Flow Payment API it become smooth and as a advantage user/customer does not leave site while making payment. Paypal will charge you $30 per month to create this account with PayPro Flow Payment system. https://manager.paypal.com/ This is where you can see everything related to your account.
In order to activate Recurring you need to make phone call to Paypal account manger and request them to enable Recurring then only it will work.

Code and examples –
This class “PayFlowTransaction.class.php” have everything you need.
Apart from that there is one more file, which you will be using to pass your form variables and it will show you result. So called instance!

What you can do with this class and code –
1. Create Recurring Billing Profile
2. Modify – Recurring Billing Amount and CC detials or anything
3. Reactivate – Reactivate Cancelled profile.
4. Cancel – You can cancel profile anytime
5. Inquiry – Details of each payment for a profile and Status of a customer’s profile
6. Payment – Retry a previously failed payment
You have to just pass correct variable and look litte bit in this documentation https://cms.paypal.com/cms_content/US/en_US/files/developer/PP_PayflowPro_RecurringBilling_Guide.pdf
In order to see this code in action you need to have your own account.

$txn->USER = ‘your_username’;
$txn->PWD= ‘You_should_ask_to_admin’;
$txn->VENDOR = ‘yourvendername_checkwith_your_admin’; //$txn->USER; //or your vendor name

  }
  catch( FraudProtectionException $fpe ) {
   echo 'Fraud Protection error: ' . $fpe->getMessage();
  }
        catch( Exception $e ) {
   echo $e->getMessage();
  }
         
?>

Code above is very easy to understand. 
//ini_set('display_errors', 1);

 //ini_set('log_errors', 1);

 //ini_set('error_log', dirname(__FILE__) . '/error_log.txt');

// error_reporting(E_ALL);
this is to show error if you have any.

and rest of them are variables.
Hope it will cut down your development time.
					

You can use UNION operator to merge the result-set of two or more SELECT statements into one array.
The default behavior for UNION is that duplicate rows are removed from the result. UNION ALL does not remove duplicate.

There are few things need to be kept in mind.

A. SELECT statement within the UNION must have the same number of columns.
B. The field should have similar data types.
C. Fields in each SELECT statement must be in the same order if not make them.
D. If column have diffrent name make column another name by using an alias with “AS” kewords as given in the example

SELECT column1 AS alias_name FROM table

Here is the full example of UNION.

	  $select_btemp_1 = "SELECT * FROM table1 WHERE enable='1' AND aid='1'";

	  $select_btemp_2 = "SELECT * FROM table1 WHERE enable='1' AND user_id='$user_id' ORDER BY  aid ASC";

	  $select_btemp =  $select_btemp_1." ".UNION." ".$select_btemp_2;

	  $btemp_query = mysql_query($select_btemp);
	  $btemp_count = mysql_num_rows($btemp_query);

	  if($btemp_count > 0)
	  {
		while($row_images = mysql_fetch_array($btemp_query))
		{ 	
			echo $row_images[temp_desc];	
		}
	  }

	

Every php programmer/developer have to resize images in web pages.
There are a lot of ways available through JavaScript, jQuery and PHP.
Here is very simple way to resize image temporarily but proportionally.
You can still keep big image file in you in your folder but when you are displaying you can make is smaller.

Jquery and java script some times does not work. So PHP way is very useful.

 ($inputwidth/$inputheight)) {
            $outputwidth = $inputwidth;
            $outputheight = ($inputwidth * $height)/ $width;
        }

        elseif (($width/$height) < ($inputwidth/$inputheight)) {
            $outputwidth = ($inputheight * $width)/ $height;
            $outputheight = $inputheight;
        }

        elseif (($width/$height) == ($inputwidth/$inputheight)) {
            $outputwidth = $inputwidth;
            $outputheight = $inputheight;
            }

echo '';

?>

Saving images from any live url is very easy with php.
Here are three ways to do this.
1. Using Curl
2. Using File functions
3. Using GD library functions.

Condition is in your server php.ini should have “allow_url_fopen” On. check you php setting using phpinfo() function.

Create a folder name “images_saved” to save your images.

Using Curl

Image ' . basename($i) . ' Downloaded Successfully';
    }else{
        echo '
Image ' . basename($i) . ' Download Failed
';
    }
}
 
function image_save_from_url($my_img,$fullpath){
    if($fullpath!="" && $fullpath){
        $fullpath = $fullpath."/".basename($my_img);
    }
    $ch = curl_init ($my_img);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_BINARYTRANSFER,1);
    curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1);
    $rawdata=curl_exec($ch);
    curl_close ($ch);
    if(file_exists($fullpath)){
        unlink($fullpath);
    }
    $fp = fopen($fullpath,'x');
    fwrite($fp, $rawdata);
    fclose($fp);
}
?>

Using File functions

Using GD library functions.

You can use this simple function to filter bad words.

Please see attachment for mysql table of frequently used 458 bad words. http://www.phpmind.com/codedemo/php-bad-word-filter/bad_word.txt.zip
You can add more word easily as you know more!!

  function bad_wordcensor($txt)
  {
    $q = mysql_query("SELECT bad_word, replacement FROM bad_words");
    while ($row_bad = mysql_fetch_array($q))
    {
      $txt = str_ireplace($row_bad['bad_word'], $row_bad['replacement'], $txt);
    }

  return $txt;
  }

echo bad_wordcensor($_POST["comments"]);

Every php coder want to store IP address of user for tracking and other different purpose.

Here is the function which i am using in my code to store ip address in db.

    function userIPAdd()
    {
       //This returns the True IP of the client calling the requested page
       // Checks to see if HTTP_X_FORWARDED_FOR
       // has a value then the client is operating via a proxy
       $userIP = $_SERVER['HTTP_X_FORWARDED_FOR'];
       if($userIP == "")
      { 
         $userIP = $_SERVER['REMOTE_ADDR'];  
      }
      // return the IP we've figured out:
      return $userIP;
    }

You can use this simple php function in different ways.

When Display_errors is off in php.ini it is hard to see where the bug is!

While you are working in server where display errors are off you can add this code on top of the page and it will show whats going on in your php code.

ini_set('display_errors', 1);
 ini_set('log_errors', 1);
 ini_set('error_log', dirname(__FILE__) . '/error_log.txt');
 error_reporting(E_ALL);

I prefer to use this code through a function or include file and when you are done you can close or disable.
