This is what I have so far:
for ($m=0; $m$num_rows2; $m++)
{
$row2 = mysql_fetch_array($result2);
echo $row2[devlanguage];
if ($m $num_rows2)
{
echo , ;
}
else
{
echo .;
}
}
My approach to this is like this:
for ($m=0; $m$num_rows2; $m++)
{
$row2 = mysql_fetch_array($result2);
if ($m0) echo ', ';
echo $row2[devlanguage];
}
echo '.';
Cheers!
Mike

RE: [PHP] IF inside LOOP?
try using this if statement instead
if ($m $num_rows2 - 1)
or even use the ?: operator
echo ($m $num_rows2 - 1 ? , : .);

Subject: [PHP] IF inside LOOP?
Hi all.
I've been fooling around with a LOOP which should show one or more text
string stored in separate rows in a DB. The trick would we to separate
them with commas (,) when there's another string to show or end it with
a period (.) if no other row is found according to the SELECT criteria.
This is what I have so far:
for ($m=0; $m$num_rows2; $m++)
{
$row2 = mysql_fetch_array($result2);
echo $row2[devlanguage];
if ($m $num_rows2)
{
echo , ;
}
else
{
echo .;
}
}
The problem is that the LOOP stops as it's told to do, keeping the ELSE
statement from doing it's work, resulting in comma separated string as
it should, but also add an extra comma at the end of it instead of a
period. What approach should I use?
Thanks in advance,

RE: [PHP] IF inside LOOP? -- SOLVED
Thanks for two things Martin: First for teaching me about the -1
operation (which seems logic now) and second, for getting me into the
?: operator. I've read something about it in the books, but didn't
tough it was really useful 'till now.
It worked perfectly. C.
