Probably easy to do but I can't seem to generate the correct regex.
Say I have this string
$string = '<h2>Header 1</h2><p>ahs da sdka dshk asd haks</p><img src="http://dummyimage.com/100x100/" width="100" height="100" alt="Alt" /><h2>Header 2</h2><p>asdkhas daksdha kd ahs</p><em>Lame</em><p>trhkbasd akhsd ka dkhas</p><h2>Header 3</h2><p>ajdas ahkds hakd</p>';
And I need it like this
$array[0] = '<h2>Header 1</h2><p>ahs da sdka dshk asd haks</p><img src="http://dummyimage.com/100x100/" width="100" height="100" alt="Alt" />';
$array[1] = '<h2>Header 2</h2><p>asdkhas daksdha kd ahs</p><em>Lame</em><p>trhkbasd akhsd ka dkhas</p>';
$array[2] = '<h2>Header 3</h2><p>ajdas ahkds hakd</p>';
...and so on if my string contains more of those H2 blocks.
So, the split-point is at H2 and it needs to keep the HTML-tags. Any pointers?
