Undefined offset problem

Hi,

My script is supposed to step through my data sets and
create new data groups.

The data is in this style:

Set 1: {A_one|A_two|A_three|A_four|A_five}
Set 2: {B_one|B_two}
…
etc.

What I my script needs to do is select the [B]first data element[/B] from all the sets of data, then select the [B]second data element[/B] from all the sets and then the third and so on. If there is no third element then the script needs to select the first element of that set again and then continue with the second in that set ( but continuing as normal with all other sets ).

So each set continues outputting sequentially and on ending returns to beginning until the desired number of groups are created..

In this case I have set the number of groups to [B]10[/B].

My output is:

Notice: Undefined offset: 5 in /home/com567b/public_html/auto_change.php on line 35 Notice: Undefined offset: 6 in /home/com567b/public_html/auto_change.php on line 35
Created New Group: 1
A_one B-two C-three D-four E-five H-eight

Notice: Undefined offset: 5 in /home/com567b/public_html/auto_change.php on line 35 Notice: Undefined offset: 6 in /home/com567b/public_html/auto_change.php on line 35
Created New Group: 2
A_one B-two C-three D-four E-five H-eight

etc … up to New Group: 10

The new groups are all the same.

I am having problems incrementing the counter
and taking it back to the beginning. ?

Any help much appreciated. 😮

[B]This is my script: [/B]
( It includes test data )

[code=php]<?php
ini_set (“display_errors”, “1”);
error_reporting(E_ALL);

set_time_limit(10);
function inStr($needle, $haystack){
return @strpos($haystack, $needle) !== false;
}

function str_replaceFirst($s,$r,$str){
$l = strlen($str);
$a = strpos($str,$s);
$b = $a + strlen($s);
$temp = substr($str,0,$a) . $r . substr($str,$b,($l-$b));
return $temp;
}

function sqn_select($pass){
$mytext = $pass;
$idx = 0;
while(inStr(“}”,$mytext)){
$rbracket = strpos($mytext,”}”,0);
$tString = substr($mytext,0,$rbracket);
$tStringToken = explode(“{“,$tString);
$tStringCount = count($tStringToken) – 1;
$tString = $tStringToken[$tStringCount];
$tStringToken = explode(“|”,$tString);
$tStringCount = count($tStringToken) – 1;
$replace = $tStringToken[$idx++];
$tString = “{“.$tString.”}”;
$mytext = str_replaceFirst($tString,$replace,$mytext);
}
return $mytext;
}

$groups = 10;
$Db_data =”
{A_one|A_two|A_three|A_four|A_five}
{B-one|B-two|B-three|B-four|B-five|B-six|B-seven|B-eight|B-nine|B-ten|B-eleven|B-twelve}
{C-one|C-two|C-three}
{D-one|D-two|D-three|D-four|D-five|D-six|D-seven}
{E-one|E-two|E-three|E-four|E-five|E-six|E-seven|E-eight|E-nine|E-ten}
{F-one|F-two|F-three|F-four}
{G-one|G-two}
{H-one|H-two|H-three|H-four|H-five|H-six|H-seven|H-eight|H-nine}
“;

for ($grp= 1; $grp<= $groups ; $grp++) {

$Db_data = str_replace(“‘”,”`”,$Db_data);

$new_group = sqn_select($Db_data);
$new_group = str_replace(chr(13).chr(10),”<br />”.chr(13).chr(10),$new_group);

$wordCount = explode(” “,$new_group);
$wordCount = count($wordCount);

echo “<br>Created New Group: $grp<br>$new_group<br><br>”;

} // end for

echo “<br><b>Total $grp New Groups created</b><br>”;
?>
[/code]

My desired output from the included test data is:

A_one B-one C-one D-one E-one F-one G-one H-one
A_two B-two C-two D-two E-two F-two G-two H-two
A_three B-three C-three D-three E-three F-three G-one H-three —> notice G goes back to one because there are only 2 elements
A_four B-four C-one D-four E-four F-four G-two H-four —> notice C goes back to one because there are only 3 elements
A_five B-five C-two D-five E-five F-one G-one H-five
A_one B-six C-three D-six E-six F-two G-two H-six —> notice A goes back to one because there are only 5 elements
A_two B-seven C-one D-seven E-seven F-three G-one H-seven
A_three B-eight C-two D-one E-eight F-four G-two H-eight
A_four B-nine C-three D-two E-nine F-one G-one H-nine
A_five B-ten C-one D-three E-ten F-two G-two H-one

Thanks for any help ?
