More Arrays

[Anon]

I have four arrays

x, y, z, and p

each array has four elements x1, x2,...

how can I build a multidimensional array that looks like

x1 y1 z1 p1
x2 y2 z2 p2
x3 y3 z3 p3
x4 y4 z4 p4

HI
From your question I understand that you need to construct a 2D array. Your array should have the syntax:
$array2D[<rows>][<columns>]

here is a sample code to loop through the array

for($i=0;$i<4;$i++) {
   for($j=0;$j<4;$j++)
      $array2D[$i][$j] = $i+$j; // some data to be stored every column.
}

Hi OOzy,

<?php

$x = array (x1,x2,x3,x4);
$y = array (y1,y2,y3,y4);
$z = array (z1,z2,z3,z4);
$p = array (p1,p2,p3,p4);

$arrays = array ($x, $y, $z, $p);

// This will print all of array x, all of array y, ..... .. .
print ('<PRE>');
while (list ($key, $value) = each ($arrays)) {
while (list ($key2, $value2) = each ($value)) {
print ($value2." ");
}
print ("<BR>");
}
print ('</PRE>');

// Or maybe you mean FLIPMODE:
// This will print all of x1, y1, z1, p1 then x2, y2, ..... .. .
// You can of course replace the print statement with an assignment to create a flipped array.

print ('<PRE>');
for ($i = 0; ($i < sizeof ($arrays)) ; $i++) {
for ($c = 0; ($c < sizeof ($arrays[0])) ; $c++) {
print ($arrays[$c][$i]." ");
}
print ("<BR>");
}
print ('</PRE>');

?>

Kind regards,

Tuurlijk!
