Array question

Anon

so i am generating a bunch of arrays, lets say called something like

disaster1[1]
disaster2[1]
disaster3[1]
diaster4[1]
diaster4[2]

so on and so on....maybe i have 25 disasters.

now i am reading this variable in from a page, i don't want to hardcode it...so what if i have a while statement maybe like

in theory, this is what i want to work in sort of pseudo code...this doesn't work, how can i fix it?

while ($x < 26)
{
echo "$disaster$x[1]";
}

use variable variables:

http://www.php.net/manual/en/language.variables.variable.php

$disaster4[1]="dsfsf";
$disaster8[1]="dsfsf";
$x=0;
while ($x < 26)
{
if (isset(${"disaster".$x}[1]))
{
echo "set<BR>\n";
};
echo $x++."<BR>";
}

and remember, NEVER EVER quote variables, only strings.

thanks, that's exactly what I was looking for!

Why not multi-dimensional arrays:

$disaster[0][0]="Chicago Fire";
$disaster[0][1]="Georgia, lights out";
$disaster[1][0]="San Francisco Earth Quake";
$disaster[1][1]="Nepal Earth Quake";
$disaster[1][2]="Great Quake of 2004";
$disaster[2][0]="Dog ate my homework";

foreach($disaster)foreach($disaster as $key => $tmp){
print $key.":::";
foreach($tmp as $key2 => $tmp2){
print $key."::".$tmp2.":";
}
print "<BR>";
}

Much cleaner than variable variables, which still have their uses, i.e. when you can't control the input data format and such.
