How to Allocate Array Values for every iteration in while loop - php

Question

$data1 = array();
$final_ttt = "15";
$items = [];
for ($j = 1; $j <= $final_ttt; ++$j)
{
$TeamNo = "t$j";
$items[] = $TeamNo;
}
print_r($items);
In while loop im getting below values
$day = 1;
$i = 0;
while($row = $qry->fetch())
{
$name = $row['name']; //a,b,c,d
$loopvalue = $row['loopvalue']; // getting 2,3,8,3,4
$data1[]=array("name" => $name,"loopvalue" => $loopvalue);
if( $i % $final_ttt == 0 )
{
$fday = "Day ".$day;
$day++;
}
}
output
name value Team day
a 2 t1,t12 1
b 3 t3,t4,t5 1
c 8 t5,t6,t7,t8,t9,t10,t11,t12 1
d 3 t13,t14,t15 1

--- We are editing the question as the solution provided does not work in certain test cases. Like the one shown in the attached image.
Here is the updated code for above image output
$lastIndex = 0;
$day = 1;
while($row = $qry->fetch())
{
$name = $row['name']; //a,b,c,d
$loopvalue = $row['loopvalue']; // getting 2,3,8,3,4
if($i==0)
{
$fday = "Day ".$day;//Day 1 for first Itration
$day = 2;
}
$team = implode(',',array_slice($items, $lastIndex, $loopvalue));
$lastIndex = $lastIndex + $loopvalue;
if($lastIndex > count($items))
{
$lastIndex = $lastIndex - count($items);
$team .= ','.implode(',',array_slice($items, 0, $lastIndex));
$fday = "Day ".$day;
$day++;
}
$data1[]=array("name" => $name,"loopvalue" => $loopvalue, "day" => $fday, 'team' => $team);
$row ++;
}
print_r($data1);

You can try something like below
$lastIndex = 0;
while($row = $qry->fetch())
{
$name = $row['name']; //a,b,c,d
$loopvalue = $row['loopvalue']; // getting 2,3,8,3,4
$team = implode(',',array_slice($items, $lastIndex, $loopvalue));
$lastIndex = $lastIndex + $loopvalue;
if($lastIndex > count($items)) {
$lastIndex = $lastIndex - count($items);
$team .= ','.implode(',',array_slice($items, 0, $lastIndex));
}
$data1[]=array("name" => $name,"loopvalue" => $loopvalue, 'team' => $team);
$row ++;
}
print_r($data1);
Will result like
Array ( [0] => Array ( [name] => a [loopvalue] => 2 [team] => t1,t2 ) [1] => Array ( [name] => b [loopvalue] => 3 [team] => t3,t4,t5 ) [2] => Array ( [name] => c [loopvalue] => 8 [team] => t6,t7,t8,t9,t10,t11,t12,t13 ) [3] => Array ( [name] => d [loopvalue] => 3 [team] => t14,t15,t1 ) [4] => Array ( [name] => e [loopvalue] => 4 [team] => t2,t3,t4,t5 ) )
Let me know if this solve your problem.
