How can I display the SubTotal on OpenCart on any page?

Currently the only global PHP command I know is:

<?=$text_items?>

This spits:

1 item(s) - £318.75

I want to get the 318.75 value so at the moment I am trying a replace but it is not working all smoothly:

$short = $text_items;
$short = str_replace("£", "", $short);
$short = str_replace("&pound;", "", $short);
$short = str_replace("-", "", $short);
$short = str_replace("&ndash;", "", $short);
$short = str_replace(" ", "", $short);
$short = str_replace("-", "", $short);
$short = str_replace("ITEMS", "", $short);
$short = str_replace("(", "", $short);
$short = str_replace(")", "", $short);
$short = str_replace("item(s)", "", $short);
$short = str_replace("ITEM", "", $short);

$total = @floatval(end(explode('£', html_entity_decode($text_items))));
  • html_entity_decode changes &pound; to £
  • end(explode('£' is giving you string after '£' character
  • finally floatval is valuating string to float.
  • @ is bypassing E_STRICT error which occurs to passing constant in end() function.

Working example

Second solution is Regexp:

preg_match_all('!\d+(?:\.\d+)?!', $text_items, $result);
echo $result[1];
