Question

I need to add a <p> tag to the beginning of each array value and a closing </p> tag at the end of each array value.

If there is a [ or ] delimiter then they need to be replaced with <p class="myclass">

Array
(
    [0] => [This is a line of text
    [1] => and another
    [2] => and yet another.] [This is another line of text
    [3] => and another
    [4] => and another] [OK, so you get the idea.
)

The above array should become:

Array
(
    [0] => <p class="myclass">This is a line of text</p>
    [1] => <p>and another</p>
    [2] => <p>and yet another.</p> <p class="myclass">This is another line of text</p>
    [3] => <p>and another</p>
    [4] => <p>and another</p> <p class="myclass">OK, so you get the idea.</p>
)

The question is: Using a foreach loop, how do I get from the first array to the second array?

Answer 1

for($i = 0; $i < count($array); $i++) {
  $array[$i] = '<p>'.$array[$i].'</p>';
  $array[$i] = preg_replace('/\]/', '</p>', $array[$i]);
  $array[$i] = preg_replace('/\[/', '<p class="myclass">', $array[$i]);
  $array[$i] = preg_replace('/<p><p/', '<p', $array[$i]);
}
