匹配特定字符之间的字符串

Question

I'm pretty bad with regex and need some help with the scenario below: How do I extract all the strings between # and / in the string below using PHP:

$text = '<a href=\"http://example.com/what-is-row#row\"><a href=\"http://example.com/what-is-code#code\">';

Here's what I tried but it pretty much returns only one match along with the # and / but I don't want the results with the characters

$pattern = "/#(.*?)\//i";
preg_match_all($pattern, $input, $matches);

Result:

array(2) { [0]=> array(1) { [0]=> string(23) "#row\"> array(1) { [0]=> string(21) "row\">

Thanks in advance

try this pattern - "/(#). ?\w /"

$text = '<a href=\"http://example.com/what-is-row#row\"><a href=\"http://example.com/what-is-code#code\">';
$pattern = "/(#).*?\w*/";

preg_match_all($pattern, $text, $matches);

/* 
$matches[0] will have 
#row
#code
now we just need to replace # with "" blank char
the below logic will do it
*/
foreach ($matches[0] as $match) {
  echo str_replace("#","",$match)."<br />";
}

Done.
