problem with Arrays, help

[Anon]

i'm the newbie in php, and i have problem
with multidimensional arrays:

there is a sample from my code:

$a=1;
while ($a <= 5) {

$this->$rights[$a][1] = 'q';
$this->$rights[$a][2] = 'w';
$this->$rights[$a][3] = 'e';
$this->$rights[$a][4] = 'r';

$a++;
}

echo ($this->$rights[1][1]);
echo ($this->$rights[1][2]);
echo ($this->$rights[1][3]);
echo ($this->$rights[1][4]);

the question is why all these 4 echos prints symbol 'r', and not 'q' 'w' 'e' 'r'??

thanks alot

Look at the first part:

$a=1;
while ($a <= 5) {

$this->$rights[$a][1] = 'q';
$this->$rights[$a][2] = 'w';
$this->$rights[$a][3] = 'e';
$this->$rights[$a][4] = 'r';

$a++;
}

this is looping 4 times updating the $a by 1 each time, so you are actually saying:

$this->$rights[1][1] = 'q';
$this->$rights[2][2] = 'w';
$this->$rights[3][3] = 'e';
$this->$rights[4][4] = 'r';

you should have writen it like this:

$this->$rights[1][$a] = 'q';
$this->$rights[1][$a] = 'w';
$this->$rights[1][$a] = 'e';
$this->$rights[1][$a] = 'r';

hope this helps.
