[RESOLVED] Arrays, How Do I Increment an Array?

wscreate

I have been working on this for the past 4 hours non-stop. I have searched the forums, other forums, the manual, and I just do not get the arrays yet.

I have found an open source email program that displays attachments. What I want to do is make "$ATTACH" in the code below to be an array so that the code will iterate and provide the results of the iteration connected to 3 variables.

$ATTACH1 // Would be a link to download.php?pid=1
$ATTACH2 // Would be a link to download.php?pid=2
$ATTACH3 // Would be a link to download.php?pid=3

-------------------- BEGIN CODE ----------------------------

if (is_array($attachments))
{
// display as list
for($x=0; $x<sizeof($attachments); $x++)
{

$ATTACH = "<li><a href=download.php?pid=" . $attachments[$x]["pid"] . ">" . $attachments[$x]["name"] . " (" . ceil($attachments[$x]["size"]/1024) . " KB)</a>";


}

}

---------- END CODE --------------------

If someone could give me a jump start, an example using my code, I will be very grateful. I am not an excellent coder, I am self taught, and arrays are giving me a lot of trouble.

Thanks in advance.

Hi, arrays can be tricky. I'm not sure I understand exactly what you're asking, but here's how you would declare that array.

$attach = array();

// Populate array w/ fake data
$attach[0]['PID'] = "1";
$attach[0]['Name'] = "Download #1";
$attach[0]['Size'] = "1024";

$attach[1]['PID'] = "2";
$attach[1]['Name'] = "Download #2";
$attach[1]['Size'] = "2048";

// This next one would be the same as using $attach[2], because
// blank brackets simply add an item to the end of the array
$attach[]['PID'] = "3";
$attach[]['Name'] = "Download #3";
$attach[]['Size'] = "3192";

You can use your "for" code to loop through, or use foreach, which I prefer. (see the manual). Did that help?

Yes, this helps. The blank bracket part, that is what I was thinking about but not getting. Thanks!
