Answer 1

Is this what you are looking for.

 $input = [ 
            "<h2>hi</h2>",
            "<p>there</p>",
            "<p>there</p>",
            "<h2>hwo ar eyou</h2>",
            "<p>Im' not bdoy</p>",
            "<h2>is is good ? </h2>",
            "<p>Not it is not</p>",
        ];
        $outputArray = [];
        $i= -1;
        foreach($input as $in){
            if (str_contains($in,'<h2>')){
                $i++;
            }
            $outputArray[$i][] = $in;
            
        }

This will be the output

[
  [
   "<h2>hi</h2>",
   "<p>there</p>",
   "<p>there</p>"
  ],
  [
    "<h2>hwo ar eyou</h2>",
    "<p>Im' not bdoy</p>"
  ],
  [
    "<h2>is is good ? </h2>",
    "<p>Not it is not</p>"
  ]
]
