php extract multiple sections of text from string

Question

I'm trying to extract the text in the following way:

$subname = "subarray({value=subarray({0.5, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48}, EXCEL*48, 1)";            
preg_match('#\{(.*?)\}#',$subname, $match,  PREG_OFFSET_CAPTURE);
print_r($match[1][1]);
$matchs = substr( $subname, 0, $match[1][1]);
print_r($matchs);

I would like to obtain the following text from $subname

1. 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48
2. EXCEL
3. *48

I'm struggling with the 2nd bit (getting the EXCEL word). I wonder whether it is possible to get preg_match to give me the rest of the string?

Answer 1

You may use

'#\{([\s\d.,]*)},\s*(\p{L}+)(\*\d+)#'

See the regex demo.

Details:

• \{ - a {
• ([\s\d.,]*) - Group 1 capturing 0+ whitespaces, digits, commas and dots
• } - a literal }
• , - a comma
• \s* - 0+ whitespaces
• (\p{L}+) - Group 2: one or more letters
• (\*\d+) - Group 3: a * and 1+ digits.

See a PHP demo below.

$subname = "subarray({value=subarray({0.5, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48}, EXCEL*48, 1)";            
$res = array();
if (preg_match('#\{([\s\d.,]*)},\s*(\p{L}+)(\*\d+)#',$subname, $match)) {
    $res = explode(", ", $match[1]);
    array_push($res, $match[2]);
    array_push($res, $match[3]);
}
print_r($res);
