Multiple Array

[Anon]

I want to have a bidimensional array and I don't know how to do it and how to insert values in it.

An exemple;

for ($i=0;$i<3;$i++){
for ($j=0;$j<3;$j++){
$tab[$i][$j]=$i+$j;
}
}

OK I know that my example is not in php but I really don;t know how to do it. I read it it the manual but I didn't find any answear to my problem. I think this is easy but I really don't get it.

Thank's for any help.

That is exactly how you create a multidimensional array. Just assign a value to it.

Example:

<?php
$mult_array[0][0] = 'upper left';
$mult_array[0][10] = 'upper right';
$mult_array[10][0] = 'lower left';
$mult_array[10][10] = 'lower right';

print $mult_array[10][0] . "\n";
?>

The output is:
lower left

Hope this helps!

Or use arrays to create your multidim array

$multidim=array(array(1,2,3) , array(4,5,6));

Your example works fine. Note you can also use arrays in really cool ways, like so:

$arr[0]["lname"]="Marlowe";
$arr[0]["fname"]="Scott";
$arr[1]["lname"]="Smith";
$arr[1]["fname"]="John";

$fields=array("lname","fname");

print "UserNames:<BR><BR>";
$rows=count($arr);
$cols=count($fields);
for ($i=0;$i<$rows;$i++){
for ($j=0;$j<$cols;$j++){
print $arr[$i][$fields[$j]];
}
print "<BR>";
}

print "Field Names: ".implode(":",$fields)."<BR>";
print 'Array Keys of $arr[0]: '.implode(":",array_keys($arr[0]))."<BR>";
