outer and inner for loop

[Anon]

Hi,

i have some problem with the code below:

<pre>
for ($j=1; $j<=2; $j++) {
$j=1;
$no_bar.$j .= "<table cellpadding=1 cellspacing=1 border=0 width=100%>\n";
for ($a=1;$a<=4;$a++) {

	$no_bar.$j .= "<tr>
					<td><input type=text name=ratio[no1_$a] value=".$ratio['no1_$a']."></td>
				</tr>\n";
}
$no_bar.$j .= "</table>\n";	

}
</pre>

I am wonder whether i can run another inner for loop? because if I remove the first for loop, everything is ok. With the script above, it will become infinitive looping.

Thanks
Louis

Not sure why you are setting $j=1 on the first line of the loop. That will probably be a problem by itself.

But I don't think this is doing what you expect:

$no_bar.$j .= ...

I believe that will assign something to $j, then concatenate the value of $no_bar with the value of $j and do nothing with the result. Probably cause an infinite loop. Maybe you intended:

$no_bar[$j] = ...

Hi,

I forgot the remove teh $j=1 on the top. I found the solution for my problem.

I think PHP doesn't accept $no_bar$j . THe purpose I put in this format because I want the new variable name is $no_bar1 .

So what I do is:

<pre>
$name = "no_bar".$j;
echo $$name;

</pre>

This will show the new variable name as '$no_bar1' and '$no_bar2'.

THanks
