Regex replace between two words

I want to replace set of string between two characters say & and [] with some other value. For example, my string is like &yyyyyyy[]=&gggggg[]=&bbbbb[]=. Now I want to replace the string between & and [] with "name" so that it looks like &name[]=&name[]=&name[]=. Now how to do it?

This should do what you want and should match anything between & and [] that is not &, [], or = 

$subject = '&yyyyyyy[]=&gggggg[]=&bbbbb[]=';    
$pattern = '/&([^\[\]\&=]+)\[\]/';
$replacement = '&name[]';
echo preg_replace($pattern, $replacement, $subject, -1);

Something like this should do it..

using preg_replaceor preg_replace_callback

\&(.*?)\[]

this should match the strings between character & and character []

preg_match_all('#\&(.*?)\[]#','&yyyyyyy[]=&gggggg[]=&bbbbb[]=',$matches);
array(2) { [0]=> array(3) { [0]=> string(10) "&yyyyyyy[]" [1]=> string(9) "&gggggg[]" [2]=> string(8) "&bbbbb[]" } 
           [1]=> array(3) { [0]=> string(7) "yyyyyyy" [1]=> string(6) "gggggg" [2]=> string(5) "bbbbb" } }

this regex is the closest i can get. Hope it helps.

preg_replace('/&([a-zA-Z0-9]+)\[\]/', '&name[]', "&yyyyyyy[]=&gggggg[]=&bbbbb[]=");

$string = '&yyyyyyy[]=&gggggg[]=&bbbbb[]=';
$result = preg_replace('/&([a-zA-Z0-9]+)\[\]/', '&name[]', $string);

// Outputs: &name[]=&name[]=&name[]=
