nested loop

foreach($test as $var1){

foreach($test2 as $var2)
{

echo '"var1: " . $var1[1] . "<br>"var2: " . $var2[1] . "<br>
\n"';
}
}

--------------------

The $tests have values just that this nested loop doesnt work i keep
getting this error message

Warning: Invalid argument supplied for foreach()

What this is saying is that $test2 is not an array.

Also, $var1[1] will not work unless $test is a two dimensional array.
The same is true for $var2[1] and $test2.

There isn't anything special about nesting foreach() loops. Something like:

foreach ($array1 as $element1) {
foreach $array2 as $element2)

works just fine. It's just important to remember that array2 will be
processed in its entirety for each element of array1.
