creare tabel cu date din mysql

Salut,poate este cineva sa ma poata ajuta la crearea unui tabel cu date extrase din baza de date..

ceva de genul

Cod: Selectaţi tot

$data = array( 0 => array( 'nume' => 'pedala', 'nume' => 'gigi' ),
  1 => array( 'nume' => 'a', 'nume' => 'b' ) );
  echo '<table>';
 foreach ( $data as $rand ) { echo '<tr>'; foreach ( $rand as $value ) { echo '<td>' . $value . '</td>'; } echo '</tr>'; }
 echo '</table>';
sursa paginii va arata asa:
<table>
<tr>
<td>pedala</td> <td>gigi</td>
</tr>
<tr>
<td>a</td> <td>b</td>
</tr>
</table>

idea este ca mie datele imi vin intr-un array de genul

Cod: Selectaţi tot

while ($row = mysqli_fetch_assoc($result)) {
 $randuri[] = $row;
}
l-am creat asa ca sa fie cu douo dimensiuni ca in exemplul de mai sus...sper ca m,-am facut inteles..
sau poate stie cineva o modalitate de a crea un tabel cu douo coloane generat cu datele ce vin din baza de date..

Array-ul nu poate contine 2 elemente diferite, cu aceeasi cheie, dupa cum apare in postarea de sus

Cod: Selectaţi tot

array( 'nume' => 'a', 'nume' => 'b' )
Ar trebui specificat exact ce coloane scoti din mysql si ce array sa formeze, numele si valoarea lor.

Salut si multumesc pentru raspunsul rapid..
am sa incerc sa dau mai multe detalii

In baza de date am tabelul asa

+----+--------+------+
| id | parinte | name |
+----+--------+------+
| 1 | 0 | val1 |
| 2 | 0 | val2 |
| 3 | 0 | val3|
| 4 | 1 | val1_1 |
| 5 | 1 | val2_1|
| 6 | 1 | val3_1 |
| 7 | 2 | val1_2|
| 8 | 2 | val2_2 |
| 9 | 2 | val3_2 |
| 10 | 3 | val1_3 |
| 11 | 3 | val2_3 |
| 12 | 3 | val3_3 |
| 13 | 0 | val4 |
+----+--------+------+
Din cate se vede val1 spre ex. este o categorie iar val3_1 este o subcategorie a lui val1

interogarea este asa

Cod: Selectaţi tot

$sql = "SELECT c.name, c.parinte, c.id FROM categorii c ORDER BY id ASC";
$result = mysqli_query($conn, $sql) or trigger_error("Query: $sql\n<br />MySQL Error: " . mysqli_error($conn));
Ca sa se vada array-ul rezultat am sa dau un var_dump()

Cod: Selectaţi tot

while ($row = mysqli_fetch_assoc($result)) {
          $categorii[] = $row;
          var_dump($categorii);
         }
rezultatul arata ceva de genul

Cod: Selectaţi tot

Daca as face var_dump($row);

Cod: Selectaţi tot

array(3) { ["name"]=> string(4) "val1" ["parinte"]=> string(1) "0" ["id"]=> string(1) "1" }
array(3) { ["name"]=> string(4) "val2" ["parinte"]=> string(1) "0" ["id"]=> string(1) "2" }

array(3) { ["name"]=> string(6) "val3_1" ["parinte"]=> string(1) "1" ["id"]=> string(2) "23" } 

array(3) { ["name"]=> string(6) "val1_2" ["parinte"]=> string(1) "2" ["id"]=> string(2) "30" } 
array(3) { ["name"]=> string(6) "val2_2" ["parinte"]=> string(1) "2" ["id"]=> string(2) "31" }
 
array(3) { ["name"]=> string(6) "val1_3" ["parinte"]=> string(1) "3" ["id"]=> string(2) "40" } 
array(3) { ["name"]=> string(6) "val2_3" ["parinte"]=> string(1) "3" ["id"]=> string(2) "41" } 
array(3) { ["name"]=> string(6) "val3_3" ["parinte"]=> string(1) "3" ["id"]=> string(2) "42" } 
array(3) { ["name"]=> string(6) "val4_3" ["parinte"]=> string(1) "3" ["id"]=> string(2) "43" }
ok din datele astea vroiam sa am un tabel su douo coloane ceva de genul
<table>
<tr>
<td>val1
val1_1
val2_1
val3_1</td> <td>val2
val1_2
val2_2</td>
</tr>
<tr>
<td>val3
val1_3
val2_3
val3_3</td> <td>val4
val1_4
val2_4
val3_4</td>
</tr>
</table>
Sper ca m-am facut inteles..
Problema este ca mie imi construieste tabelul dar in unele locuri am cate 3 coloane in altele doar una poate nu este buna metoda mea si poate stia cineva alta

Multumesc

Am inteles, dar daca ai numar diferit de coloane, nu stiu vreo solutie, adica de unde sa cunosti cand sunt 3 coloane si cand doar una.
