Answer 1

Make use of explode and array_combine functions
akshay#ideapad:~$ cat test.php
<?php
$input = array(
array( "lvid" => "01-3234", "status" => 0, "totals" => 500, "tgls" => "2020-05-24" ),
array( "lvid" => "01-3234", "status" => 1, "totals" => "100,100", "tgls" => "2020-05-24,2020-05-25" )
);
// your given input samples
print_r($input);
// process and create new array
$out=array();
foreach($input as $item)
{
$toadd = array_combine(
explode(",",$item["tgls"]),
explode(",", $item["totals"])
);
if(isset($out[$item['lvid']]))
{
$out[$item['lvid']][] = $toadd;
}else
{
$out[$item['lvid']] = array($toadd);
}
}
// finally expected output
print_r(array($out));
Tested on:
akshay#ideapad:~$ php --version
PHP 7.4.6 (cli) (built: May 14 2020 10:02:44) ( NTS )
Output:
akshay#ideapad:~$ php test.php
