如何在php变量中检查货币代码？

Question

I want to know what currency code lies in my variable value.

For example:

$var = "$200";
$check = array("$", "AU$", "CA$", "£", "€", "¥");

If $var has "$"
$currency = USD

else if $var has "£"
$currency = GBP

and so on..

What I was trying is:

$result = strpos($var, $check);
if ($result === '$') {
$currency = 'USD';
} else if ($result === '£') {
$currency = 'GBP';
| else ...

Answer 1

you can do like this

$var = "$200";
$check = array("$"=>'USD', "AU$"=>'aus', "CA$"=>'cas', "£"=>'GBP', "€"=>'ee', "¥"=>'yy');

$symbol = str_replace(range(0,9),'',$var);

$currency = $check[$symbol]?$check[$symbol]:'';
