Array

[scialom]

Hi,

I am getting 2 type of vars from my db:
$job_id
$po_id

I want to create an array with both of them.

So I have this loop:
$i=0;
while ($db->next_record()) {
$arr[$i] = $job_id

$i++
}

How can I add the $po_id to this array and create a multi-dimensional array?

Thanks,
Assaf

This is one way:

while ($db->next_record()) {
	$arr[] = array($job_id, $po_id);
}

Basically it assigns arrays as elements of an array.

Of course, how to do it depends on what exactly do you want to do.

Thanks,

But how can I recall the values? when I write
echo $arr[0] I get:
Array

What I try to do is to have an array with these 2 vars and then sort them.

for example:

id job_id po_id
0 133 10001
1 142 10000
2 143 10001

And then sort the array by po_id

Thanks,

Use $arr[0][1]

If you're trying to sort data retrieved from a database, then it is usually better to sort using the database.
