PHP Easter Egg / 1 April

Well, it just so happens that if you add this string :
?=PHPE9568F36-D428-11d2-A769-00AA001ACF42
 at the end of any URL that is a PHP page (www.somewebsite.com/somephppage.php?=PHPE9568F36-D428-11d2-A769-0z0AA001ACF42) you will see a funny little picture of a dog.
for every version of PHP there is a difference image

For example: http://www.php.net/downloads.php?=PHPE9568F36-D428-11d2-A769-00AA001ACF42

 Basically, every PHP expert know that there are 4 famous queries you can send to a PHP page:

Query 1 - ?=PHPE9568F36-D428-11d2-A769-00AA001ACF42
This is the most interesting and funny query,  displays an funny image.

Query 2 - ?=PHPE9568F35-D428-11d2-A769-00AA001ACF42
Used by PHPINFO to show the Zend Logo, it will work on any php page

Query 3 - ?=PHPE9568F34-D428-11d2-A769-00AA001ACF42
Used by PHPINFO to show the Zend Logo, it will work on any php page.

Query 4 - ?=PHPB8B5F2A0-3C92-11d3-A3A9-4C7B08C10000
shows the PHP development credits.

Also, if you will look at the PHPINFO at 1 in April, the PHP Logo is replaced by the funny images above.

enjoy,

PHP Casting problem in php4 and php5

PHP Casting problem in php4 and php5

In PHP4, We could CAST a variable like this:

class casttest {
function set_id($id) {
$this-> = $id;
}
}
$test1 = new casttest;echo (int) $test1, “\n”;As you probably guest, in PHP4 the result will be 1 because the variable we printed has a value,
On the other hand, in PHP5 we will receive this error:

Php Data Grid - 1

 I couldn’t find a good php OS Data Grid Class, so let’s learn how to write one together.

 1) The first step will be to create a new folder with the name “arpsdatagrid”
 2) Create new file under “arpsdatagrid” folder with the name “arpsdgclass.php”
 3) Lets start writing the file

Notes:
1) I’m writing this class with almost no ready made Array functions, just for best understanding of php.
2) There is a reason why i’m using the $dataheaders Array, it’s for future developing of our class.

<?php

class datagrid
{
  var $datares; //Array of Data
  var $cellsnum; //Size Of $datares
  var $dataheaders; //Array of Data Headers

   function datagrid($datares,$dataheaders)
   {
     $this->datares=$datares; //Setting Class Value
     $this->cellsnum=sizeof($datares); //Setting Class Value
     $this->dataheaders=$dataheaders; //Setting Class Value
     return true;
   }
 
 function gettable() //Return String that contain table with all the Data
  {
   $array=$this->datares; //For easy use
   $s=”<table border=1><tr>”; //Table Set
    for($i=0;$i<sizeof($this->dataheaders);$i++) //get every header
     {
      $s.=”<td class=\”datagridheadertd\”>”.$this->dataheaders[$i].”</td> \n”;
     }
  $s.=”</tr>”;
    for($i=0;$i<sizeof($array);$i++) //for every value at our Data Array
    {
     $s.=”<tr>”;
      for($x=0;$x<sizeof($this->dataheaders);$x++)  //Getting Data Headers
       {
        $s.=”<td>”.$array[$i][$this->dataheaders[$x]].”</td>”;
       }
    $s.=”</tr>”; 
  }
   $s.=”</table>”;
   return $s;
  }
  
} //Closing the class

?>

How to use it?

Let’s say we have an Array named $array, the array contain

{
  $array[0][’FNAME’]=’Aviv’;
  $array[0][’LNAME’]=’Ronen’;
  $array[1][’FNAME’]=’Aviv2′;
  $array[1][’LNAME’]=’Ronen2′;
}

Basically, what we need to do is very simple:

1) $headersarray[0]=’FNAME’; //Setting the headers Array
     $headersarray[1]=’LNAME’;

2) $datagrid=new datagrid($array,$headersarray); // Setting a Data Grid.
$tablegrid=$datagrid->gettable(); //Fetching the table string to $tablegrid

echo $tablegrid; //Printing the table string

The result will be:

Walla! 
Enjoy!
