Interesting it wouldn't run.. perhaps that's a place to investigate?
And just what is wrong with the old cr/lf sequence? How would you
have done
it?
If it is being sent to a browser, which i suspect given the html
entities encoding, i would have used "".
If it is being sent to a terminal or file, I would have used "\n".
What do you mean 'this alone .'?
Merely that the construction I see shouldn't matter whether you use $j
or $i+1.

Am i reading this correctly: the first variable is j (jay) the second

This alone doesn't explain anything...

Since this is the only place $j is used, try subbing in $i+1 and
see what
you get.
if ($row['user_priv']<> "")
echo ' ('.$row['user_priv'].')

This is really rather a strange way of getting a line break.
else
echo '

The output I get is:
1-smith5
f-ginerjm (M)
g-smith8
While the alpha parts are valid, the index is only correct for
the first
one
(0) obviously.

[PHP] Re: echo?
As Richard proved my problem was caused by my use of the archaic cr/lf character pair. Once I found the correct syntax for using \n my output of the loop counter worked. thanks for all the suggestions. My first experience on a PHP newsgroup and it was a postiive one. I've spent the last 12+ years using newsgroups for Paradox development and this group is *just* as supportive and knowledgeable. (no jokes about using paradox for so long. If your users can manage on a desktop solution, pdox can't be beaten for what it could/can do.) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Why not try some basic debugging strategies and see what you get?
Try:
for ($i=0; $i<$rows; $i++)
{
var_dump($i);
$j = $i+1;
$row = mysql_fetch_array($qrslt);
echo $j.'-'.$row['userid'];
var_dump($j);
if ($row['user_priv']<> "")
echo ' ('.$row['user_priv'].')
';
else
echo '
';
}
The output you've posted, that's rendered output, right? What's the raw
output?
By the way, the code snippet you gave us is not complete. Is there anything
else? As Dan noticed earlier, judging from that code snippet only, there
must be something else funky going on.

just so that if I have a query with 1 cell which is 0, or '', I don't
abort the loop.

with the \n, it does work in a textarea. you must put the \n inside
the "", so:
$q = 'select * from director_records ';
$qrslt = mysql_query($q);
$rows = mysql_num_rows($qrslt);
for ($i = 0; $i < $rows; $i++)
{
$row = mysql_fetch_array($qrslt);
echo ($i + 1) .'-'. $row['userid'];
if ($row['user_priv'] != "")
echo ' ('. $row['user_priv'] .')';
echo "\n";
}
give that a try

I am outputting to a on an html page. A doesn't work, nor does \n, hence the .

while(False !== ($row = mysql_fetch_array($qrslt)){
}
just so that if I have a query with 1 cell which is 0, or '', I don't
abort the loop.

Re: [PHP] Re: echo?
Hi after of the for, u can use it shoulds back the class of variable, by example "its is string" "its is int" etc for ($i=0;$i<$rows;$i++) echo $i.' '.$row['itemname']; echo gettype($i); Can be that you must define before the class of this variable, because, the system is thinking this is a string class data or hexa etc. grettings and sorry for my written english ;) -- Ricardo ___ IT Architect website: http://www.pulsarinara.com

Why not try some basic debugging strategies and see what you get?
Try:
for ($i=0; $i<$rows; $i++)
{
var_dump($i);
$j = $i+1;
$row = mysql_fetch_array($qrslt);
echo $j.'-'.$row['userid'];
var_dump($j);
if ($row['user_priv']<> "")
echo ' ('.$row['user_priv'].')
';
else
echo '
';
}
The output you've posted, that's rendered output, right? What's the raw output?
By the way, the code snippet you gave us is not complete. Is there anything
else? As Dan noticed earlier, judging from that code snippet only, there must
be something else funky going on.

I couldn't understand why you're getting characters, so I thought I'd
have a go myself. First, some DDL and DML to recreate your data:
create table director_records (userid char(16), user_priv char(8));
insert into director_records (userid, user_priv) values ('smith5',
''),('ginerjm','M'),('smith8','');
Now when I ran your code I got:
1-smith5
f-ginerjm (M)
g-smith8
That is, all but the first result has
x in front of it. These are
HTML entities that display as characters and it so happens that f
is 'j' and g is 'g'. Strictly, these entities should be terminated
with a semi-colon (i.e. f and g), but your browser is
'obligingly' making sense of the 'bad formatting' and this is why
you're getting characters.
BTW, an alternative to your for construct would be to use a while loop
to iterate through a data table. e.g. in your case, I'd have used:
$q = 'select * from director_records ';
$qrslt = mysql_query($q);
$i = 1;
while ($row = mysql_fetch_array($qrslt)){
echo $i++ . '-' . $row['userid'];
if ($row['user_priv']<>""){
echo " (" . $row['user_priv'] . ")";
}
echo "\n";
}

You're using HTML-encoded entities for 0x0d and 0x0a. You can simply use 0x0d and 0x0a instead. If you're running this in a web context, you should use "" instead of CRLF. At the command line, I'm not familiar with running PHP on Windows. In *nix environments, it's enough to use "\n", just as they do in C. It might even work in Windows; I don't know.

it?

Kinda new to this, but I've been puttering/writing for about 3 weeks now and

Tried to echo the $i value within a for loop as part of the list of items I
was building
Something like
for ($i=0;$i<$rows;$i++)
echo $i.' '.$row['itemname'];
I expected to see :
1 item1
2 item2
...
...
but instead I got
1 item1
f item2
Yes - an 'f' and not a 2.
Tried it some more with this:
for ($i=1;$i<10;$i++)
echo $i." item".'';
and got
c item
d item
e item
f item
g item
and so on.
It seems that I can only output the value of $i if I output a string in
front of it
echo ' '.$i;
works fine but
echo $i;
does not.
Any ideas?
If off your subject a bit; but, I suggest using
$i=0;
foreach($row as $value)
{
echo "$i $value\n";
$i++;

Once that painful step is taken, you can modify the output methodology to your heart's content. This sounds like an excellent object lesson in the separation of logic from markup. If you design your applications to first figure out what to output and then to output it as one or more solid lumps, you can more easily tweak the logic or the markup or the output method without messing with the others.

Thanks all!

I'm not sure I understand the question.
You could do foreach($arr as $key => $value) { print($key); }.
There are also a number of functions that get the current key on the
array's pointer:

OK, I get it now. I had forgotten that PHP output is text, as opposed to the result produced by HTML. When the documentation states that the newlines will be output as well it means that literally -- not that the browser will output the newlines. Thanks for jumping onto this.

They do the same but why?
The question that drives us (nice quote!) is if we gain any speed to use

RE: [PHP] Re: echo vs printf
print, echo, and printf are all available to help different coders code in their own style. So if you're used to just using echo in "shell", or print in perl/basic or perhaps printf, in c/c++/java/asp, there you go. Make a language easy to get stuff out of, and you can have a really quick user base. -- Austin Gonyou Systems Architect, CCNA Coremetrics, Inc.

[PHP] Re: echo vs printf
don't echo and printf do different jobs ? as i understand it echo will dump anything to screen, fprint will accept formatted text args like "you owe me %d dollars",$owed_amount) or something like that. i kind of use print by itself (harking back to the old days of basic etc) but use echo quite a lot. only use printf when i have to put cash amounts in and stuff like that.
