php - 如何检查php变量中的货币代码？

Question

我想知道我的变量值中包含什么货币代码。

例如:

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

If $var has "$"
$currency = USD

else if $var has "£"
$currency = GBP

and so on..

我正在尝试的是:

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

你可以这样做

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

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

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