Code: 
$pattern = '/\-{58}(.*?)\-{58}|$/s';
(assuming that I have counted the number of dashes correctly.) You need to match the end of subject OR the dashes to capture the final segment.

Hi jpadie,

I used your exact pattern, but didn't work as i'm still getting the same results..

Code: 
preg_match_all('/\-{58}(.*?)\-{58}|$/s', $content, $content0);

sorry. didn't read the question carefully enough. you need to make the second assertion zero width with a lookahead (?=) otherwise the regex consumes the dashes and the start of the assertion does not get matched in the second instance.

Code: 
$pattern = '/\-{58}(.*?)(?=\-{58}|$)/s';

you have totally helped me out on this one... can't thank you enough!!!!

no worries. You can achieve the same goal without a regular expression of course.

Code: 
$separator = '';
for($i=0;$i<58;$i++) $separator .= '-';
$matches = explode($separator, trim($text,'-'));
echo '<pre>';
print_r($matches);
