php - How to parse column separated key-value text with possible multiline strings -


i need parse following text:

first: 1 second: 2 multiline: blablablabla bla2bla2bla2 bla3b , key: value in middle if strting fourth: value

value string or multiline string, @ same time value contain "key: blablabla" substring. such subsctring should ignored (not parsed separate key-value pair).

please me regex or other algorithm.

ideal result be:

$regex = "/some regex/"; $matches = []; preg_match_all($regex, $html, $matches); // $mathes has key , value parsed pairs, including multilines values

thank you.

i tried simple regexes result incorrect, because don't know how handle multilines:

$regex = "/(.+?): (.+?)/"; $regex = "/(.+?):(.+?)\n/"; ...

you can pattern:

$pattern = '~(?<key>[^:\s]+): (?<value>(?>[^\n]*\r)*?[^\n]*)(?=\r\s+:|$)~';  preg_match_all($pattern, $txt, $matches, preg_set_order);  print_r($matches);
