Get string between - Find all occurrences PHP

Question

I found this function which finds data between two strings of text, html or whatever.

How can it be changed so it will find all occurrences? Every data between every

I also needed the text outside the pattern. So I changed the answer from raina77ow above a little:

function get_delimited_strings($str, $startDelimiter, $endDelimiter) {
    $contents = array();
    $startDelimiterLength = strlen($startDelimiter);
    $endDelimiterLength = strlen($endDelimiter);
    $startFrom = $contentStart = $contentEnd = $outStart = $outEnd = 0;
    while (false !== ($contentStart = strpos($str, $startDelimiter, $startFrom))) {
        $contentStart += $startDelimiterLength;
        $contentEnd = strpos($str, $endDelimiter, $contentStart);
        $outEnd = $contentStart - 1;
        if (false === $contentEnd) {
            break;
        }
        $contents['in'][] = substr($str, $contentStart, $contentEnd - $contentStart);
        $contents['out'][] = substr($str, $outStart, $outEnd - $outStart);
        $startFrom = $contentEnd + $endDelimiterLength;
        $outStart = $startFrom;
    }
    $contents['out'][] = substr($str, $outStart, $contentEnd - $outStart);
    return $contents;
}

Usage:

    $str = "Bore layer thickness [2 mm] instead of [1,25 mm] with [0,1 mm] deviation.";
    $cas = get_delimited_strings($str, "[", "]");

gives:

array(2) { 
    ["in"]=> array(3) { 
        [0]=> string(4) "2 mm" 
        [1]=> string(7) "1,25 mm" 
        [2]=> string(6) "0,1 mm" 
    } 
    ["out"]=> array(4) { 
        [0]=> string(21) "Bore layer thickness " 
        [1]=> string(12) " instead of " 
        [2]=> string(6) " with " 
        [3]=> string(10) " deviation" 
    } 
}
