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!
