Dave,
Foreach is an iterator over an array. Your $row is a pointer to a db result
set. If you were to pass the $row result set to the foreach as an array, you'd
get what you think you should
Www.php.net/foreach

product_id product price
1 Milk 2.59
2 bread 1.05
And when $row is equal to 0 the output I get is
1 1 Milk Milk 2.59 2.59 Which is printed to the screen according to how many
rows are in the db I belive.
So my question is why this behavior? I was expecting something like a while
loop.
Code please.

Thanks Bastien.
Heres what I started with:
$result = mysql_query("SELECT * FROM items");
$row = mysql_fetch_array($result);
foreach($row as $rows){
$row = 0;
if($row == 0){
echo $rows;
} else{
echo "Too expensive I'm going home LOL";
}
}
Here's what I ended up with after you gave me the advise:
$result = mysql_query("SELECT * FROM items");
$rows = array();
while($row = mysql_fetch_array($result))
$rows[] = $row;
foreach($rows as $row){
$product = $row['product'];
$price = $row['price'];
echo "$product ";
echo "$price ";
$justright = 0;
$toohigh = 5; //I was going to use this to check if the price was too high
just so I could use an elseif in the exercise,
but I realized that
it would only work if the if() evaluated to
false, which would be
impossible. Ahhh pizz on it, it was fun anyway!
:-)
if($justright <= $price){
echo "Not bad. I'll buy it.<br />";
} else
echo "Too expensive I'm going home LOL ";
}
It's a dumb script that makes no sense but I had a blast doing this. When
things start coming together like this, it gets so gratifying. :-)

Once you know the answer, then the question is easy ...
In order to use your link one has to know how SNMP works and understand things
like 'object_id' ...
http://www.jffnms.org/ turned up and is just what I was looking for and can see
the devices and report what each is providing. I still need to get cacti to see
those devices, but once one has SOMETHING working then things get a lot easier
:) The question I should have been asking was "php network monitoring system"
I still need to add monitoring of the domain list and that each domain is being
correctly returned, but now I have something I can pull apart and play with and
push my own parts back into.

Many receiving e-mail clients will not show external images. External
images are used by spammers to trach if a message is read.

true;
you could embed images in email..
http://www.campaignmonitor.com/blog/post/1761/embedding-images-in-email/
so you could use this (or similar) to write the email:
echo '<img
src="data:image/png;base64,'.base64_encode(file_get_contents('test.png'));.">';
(i don't know if it works :D )

Actually this is bad practice ... it blows up your code.
Use attachments for that.
