一款实用的PHP货币换算程序代码哦，有需要的朋友可以参考一下。代码如下

复制代码

}is";

preg_match_all($pattern,$buffer,$xml_rates);

array_shift($xml_rates);

for($i=0;$i

$exchange_rate[$xml_rates[0][$i]] = $xml_rates[1][$i];

}

$conn = mysql_connect($this->mysql_host,$this->mysql_user,$this->mysql_pass);

$rs = mysql_select_db($this->mysql_db,$conn);

foreach($exchange_rate as $currency=>$rate) {

if((is_numeric($rate)) && ($rate != 0)) {

$sql = "SELECT * FROM ".$this->mysql_table." WHERE currency='".$currency."'";

$rs = mysql_query($sql,$conn) or die(mysql_error());

if(mysql_num_rows($rs) > 0) {

$sql = "UPDATE ".$this->mysql_table." SET rate=".$rate." WHERE currency='".$currency."'";

} else {

$sql = "INSERT INTO ".$this->mysql_table." VALUES('".$currency."',".$rate.")";

}

$rs = mysql_query($sql,$conn) or die(mysql_error());

}

}

}

}

/* Create the currency exchange table */

function createTable() {

$conn = mysql_connect($this->mysql_host,$this->mysql_user,$this->mysql_pass);

$rs = mysql_select_db($this->mysql_db,$conn);

$sql = "CREATE TABLE ".$this->mysql_table." ( currency char(3) NOT NULL default '', rate float NOT NULL default '0', PRIMARY KEY(currency) ) ENGINE=MyISAM";

$rs = mysql_query($sql,$conn) or die(mysql_error());

$sql = "INSERT INTO ".$this->mysql_table." VALUES('EUR',1)";

$rs = mysql_query($sql,$conn) or die(mysql_error());

$this->downloadExchangeRates();

}

}

?>

Copy the above code into a new file and save it as CurrencyConverter.php. Whenever you need to make a conversion just include the class file and call the ‘convert’ function. You will need to enter your own mysql database variables such as the login details. The example below will convert £2.50 GBP into US Dollars ($).

代码如下
