Question

I would need to get the text between certain strings with preg_match_all. I’ve tried using alternation, but I’m not getting the right info out. What I need is to get the randomtext between weekday-strings. From Friday it should go to the end of the text.

My data is as follows:

Monday 1.1.
randomtext
randomtext
Tuesday 2.1.
randomtext
randomtext
Wednesday 3.1
randomtext
randomtext
Thusday 4.1.
randomtext
randomtext
randomtext
Friday 5.1
randomtext
randomtext

What I have now is this, but it only captures the stuff after Monday, when it should stop to Tuesday and then do it again:

/(Monday|Tuesday|Wednesday|Thursday|Friday)([\s\S]+)/

Any ideas?

You can use preg_split().

$day_pattern = '/([a-z]+?day [\d\.]+\n)/i';
$bits = preg_split(
    $day_pattern,
    $str,
    null,
    PREG_SPLIT_NO_EMPTY | PREG_SPLIT_DELIM_CAPTURE
);
if ($bits)
    foreach($bits as $bit)
        echo preg_match($day_pattern, $bit)
            ?
            '<h3>'.$bit.'</h3>'
            :
            '<p>'.$bit.'</p>';

Outputs

<h3>Monday 1.1.</h3>
<p>randomtext
randomtext</p>
<h3>Tuesday 2.1.</h3>
<p>randomtext
randomtext</p>
<h3>Wednesday 3.1</h3>
<p>randomtext
randomtext</p>
<h3>Thusday 4.1.</h3>
<p>randomtext
randomtext
randomtext</p>
<h3>Friday 5.1</h3>
<p>randomtext
randomtext</p>
