Answer 1

<?php
$ps    = array();
$count = preg_match_all('/<p[^>]*>(.*?)<\/p>/is', $a, $matches);
for ($i = 0; $i < $count; ++$i) {
    $ps[] = $matches[0][$i];
}

That could be one way. Or you could use a loop with strpos

Answer 2

Using DOMDocument and DOMXPath (a bit overkill if only a simple solution is needed):

$dom = new DOMDocument();
$dom->loadHTML($a);
$domx = new DOMXPath($dom);
$entries = $domx->evaluate("//p");
$arr = array();
foreach ($entries as $entry) {
    $arr[] = '<' . $entry->tagName . '>' . $entry->nodeValue .  '</' . $entry->tagName . '>';
}
print_r($arr);
