Cyklus + pole – PHP – Fórum – Programujte.com

Prosim vie mi nieto poradit preco mi to nefunguje.
Na zaciatku suboru mam premene $tpid[0] az $tpid[19] a chcem ich dostat do pola $tpid.

$i=0;
while ($i<20)
{
$tpid[$i] = $tpid_[$i];
$i++;
}

vopred diky

To JannyM : tak ted ti nerozumim...
Na zaciatku suboru mam premene $tpid[0] az $tpid[19]
nejsou promenne, ale pole
a chcem ich dostat do pola $tpid.
uz je tam mas

To Akacko : nemam ked dam print_r ($tpid) vypise mi
Array ( [0] => [1] => [2] => [3] => [4] => [5] => [6] => [7] => [8] => [9] => [10] => [11] => [12] => [13] => [14] => [15] => [16] => [17] => [18] => [19] => )
a pritom mam v kazdej premenej hodnotu

aby som to upresnil bo som si vsimol ze som to tam napisal zle premene su $tpid_[0] az $tpid_[19] a tie chcem dostat do pola $tpid

To JannyM :
tak potom do tech promennych asi nic neukladas. Jeste mi do hlavy nejde tento radek kodu

$tpid[$i] = $tpid_[$i]; 

$tpid_0 = $_REQUEST["tpid_0"]; $tpid_1 = $_REQUEST["tpid_1"]; $tpid_2 = $_REQUEST["tpid_2"]; $tpid_3 = $_REQUEST["tpid_3"]; $tpid_4 = $_REQUEST["tpid_4"];
$tpid_5 = $_REQUEST["tpid_5"]; $tpid_6 = $_REQUEST["tpid_6"]; $tpid_7 = $_REQUEST["tpid_7"]; $tpid_8 = $_REQUEST["tpid_8"]; $tpid_9 = $_REQUEST["tpid_9"];
$tpid_10 = $_REQUEST["tpid_10"]; $tpid_11 = $_REQUEST["tpid_11"]; $tpid_12 = $_REQUEST["tpid_12"]; $tpid_13 = $_REQUEST["tpid_13"]; $tpid_14 = $_REQUEST["tpid_14"];
$tpid_15 = $_REQUEST["tpid_15"]; $tpid_16 = $_REQUEST["tpid_16"]; $tpid_17 = $_REQUEST["tpid_17"]; $tpid_18 = $_REQUEST["tpid_18"]; $tpid_19 = $_REQUEST["tpid_19"];

$i=0;
while ($i<20)
{
$tpid[$i] = $tpid_[$i];
$i++;
}

print_r ($tpid);

ten riadok by mal vlozit do pola $tpid s klucom 1 premenu tpid_['1']

Tak mezi $tpid_0 a $tpid_[0] je obrovsky rozdil. Zkus toto:

$i=0;

while ($i<20)

{

	$var = "tpid_" . $i;

	$tpid[$i] = $$var;

	$i++;

} 

To Akacko : super diky moc facha

To Akacko : a este taka otazocka $$var preco su tam dva $$

To JannyM :
Protoze nad tim jsem vytvoril nazev promenne

$var = "tpid_" . $i;

$tpid[$i] = $$var;
