html - Multi-dimensional arrays php to table rowspan -

i'm stuck @ these.

this array: $tabel3 = array (  array ( "progdas" => "java", "sks" => "3", "prior" => "2" ), array ( "progdas" => "c#", "sks" => "6", "prior" => "1" ), array ( "mat" =>  "dasar", "sks" => "3", "prior" => "1" ), array ( "mat" =>  "lanjut", "sks" => "3", "prior" => "3" ),  ); 

and code showing @ tables :

<?php echo "tabel 3<br />";   echo "<table width='auto' border='1'>";     //header     echo "     <table width='auto' border='1'  >     <tr>       <th colspan='2' scope='col'>mata kuliah</th>       <th width='auto' scope='col'>jumlah sks</th>       <th width='auto' scope='col'>prioritas</th>     </tr>     ";   foreach ($tabel3 $rows => $row) {        //isi            echo "<tr>";      if ($cell == "progdas") {         echo "<th width='auto' rowspan='2' scope='row'>pemrograman dasar</th>";         foreach ($row $col => $cell)     {          echo "<td>" . $cell. "</td>";            }         }          else {             echo "<th width='auto' rowspan='2' scope='row'>matematika</th>";     foreach ($row $col => $cell)     {          echo "<td>" . $cell. "</td>";            }                    }       echo "</tr>"; }      echo "</table>";         ?> 

i want tables looked :

-----------------------------------------------------  mata kuliah               | jumlah sks | prioritas  | -----------------------------------------------------  pemrograman dasar|_java___|____________|____________| _________________|_c#_____|____________|____________|  matematika       |_dasar__|____________|____________| _________________|_lanjut_|____________|____________| 

does know how rowspan data "pemrograman dasar " , "matematika"? bad result @ code.

first, need rebuild array

foreach ($tabel3 $row) {     $row_keys = array_keys($row);     $rebuilded[$row_keys[0]][] = $row;  } 

after can next array:

array (      [progdas] => array (          [0] => array ( [progdas] => java [sks] => 3 [prior] => 2 )          [1] => array ( [progdas] => c# [sks] => 6 [prior] => 1 )      )      [mat] => array (          [0] => array ( [mat] => dasar [sks] => 3 [prior] => 1 )          [1] => array ( [mat] => lanjut [sks] => 3 [prior] => 3 )  )  

)

after reorganization can construct html code

<?php echo "tabel 3<br />";   echo "<table width='auto' border='1'>"; echo " <table width='auto' border='1'  > <tr>   <th colspan='2' scope='col'>mata kuliah</th>   <th width='auto' scope='col'>jumlah sks</th>   <th width='auto' scope='col'>prioritas</th> </tr> ";   foreach ($rebuilded $key => $group) {  echo "<tr><th width='auto' rowspan='".count($group)."' scope='row'>".($key == "progdas" ? "pemrograman dasar" : "matematika")."</th>"; foreach ($group $row) {     echo "<td>" . ($key == "progdas" ? $row['progdas'] : $row['mat']). "</td><td>" . $row['sks']. "</td><td>" . $row['prior']. "</td></tr>";        } 

}

echo "</table>";         

?>
