I want to get 344747585151010c745359555d581a575b59
from the string.
[a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="344747585151010c745359555d581a575b59"]
I'm tried the following PHP to capture it:
preg_match_all("/<a [^>]*data-cfemail=\"?([^\">]+)\"?>/", $input_lines, $output_array);
