I have a string of below type.

Now i want to split this string into array cell. like this one

term => 'test1', 
num => 3,
info => array{ [0]=> 275, [1]=> 435, [2]=> 900 }

can any one know a regular expression pattern for this string….thanks in advance.

You probably want to use preg_match_all.

$string = "[test1,3,(257,305,435,900)]";

preg_match_all('/\[(?P<term>\w+),(?P<num>\d+),\((?P<info>[\d,]+)\)\]/', $string, $out);

$results = array (
   'term' => $out['term'][0],
   'num'  => $out['num'][0],
   'info' => explode(',', $out['info'][0])
);

var_dump($results);
