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

Question

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);

Isn't there a way to get the variable directly instead of having to parse it through the text like this? — Pacerier, Oct 04 '14 at 22:28

$total = @floatval(end(explode('£', html_entity_decode($text_items))));

html_entity_decode changes £ 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];

I only want the value `318.75` no pound signs, no dashes. Just that value. Basically the value after the £ GBP sign. – TheBlackBenzKid Aug 23 '12 at 22:40
yeah so i gave you two solutions. Did you even check on my examples? – Peter Aug 23 '12 at 23:34
Thanks. What is fast and better to use? Could you also explain the Regex. – TheBlackBenzKid Aug 24 '12 at 12:22
I recommend you 1st solution. Regex is simply looking for two decimals and dot `.` in string – Peter Aug 24 '12 at 13:28
