Question

I’m trying to match the numbers inside (”)

$linkvar ="<a onclick="javascript:open('597967');" class="links">more</a>"


preg_match("^[0-9]$",$linkvar,$result); 

Answer 1

Your regex will only match if the string is exactly one digit. To match only the digits inside the quotes, use:

preg_match("/'(\d+)'/", $linkvar, $result);
var_dump($result[1]);
