在PHP中解析时无格式化钱

Question

有没有办法得到像这样的字符串的浮点值:75,25 €除了parsefloat(str_replace(',', '.', $var))？

我希望这依赖于当前的网站语言,有时逗号可以用点替换.

Answer 1

这是一个更复杂/更慢的解决方案,但适用于所有语言环境.因为@ rlenom的解决方案仅使用点作为小数分隔符,并且某些语言环境(如西班牙语)使用逗号作为小数分隔符.

<?php

public function getAmount($money)
{
    $cleanString = preg_replace('/([^0-9\.,])/i', '', $money);
    $onlyNumbersString = preg_replace('/([^0-9])/i', '', $money);

    $separatorsCountToBeErased = strlen($cleanString) - strlen($onlyNumbersString) - 1;

    $stringWithCommaOrDot = preg_replace('/([,\.])/', '', $cleanString, $separatorsCountToBeErased);
    $removedThousandSeparator = preg_replace('/(\.|,)(?=[0-9]{3,}$)/', '',  $stringWithCommaOrDot);

    return (float) str_replace(',', '.', $removedThousandSeparator);
}

测试:

['1,10 USD', 1.10],
['1 000 000.00', 1000000.0],
['$1 000 000.21', 1000000.21],
['£1.10', 1.10],
['$123 456 789', 123456789.0],
['$123,456,789.12', 123456789.12],
['$123 456 789,12', 123456789.12],
['1.10', 1.1],
[',,,,.10', .1],
['1.000', 1000.0],
['1,000', 1000.0]

注意事项:如果小数部分超过两位数,则会失败.

您可以使用

• NumberFormatter::parseCurrency - 解析货币编号

手册示例:

$formatter = new NumberFormatter('de_DE', NumberFormatter::CURRENCY);
var_dump($formatter->parseCurrency("75,25 €", $curr));

得到: float(75.25)

请注意,默认情况下不启用intl扩展.请参阅安装说明.

使用ereg_replace

$string = "$100,000";
$int = ereg_replace("[^0-9]", "", $string); 
echo $int;

输出

百万

function toInt($str)
{
    return (int)preg_replace("/\..+$/i", "", preg_replace("/[^0-9\.]/i", "", $str));
}

更新

<?php
$string = array("$1,000,000.00","$1 000 000.00","1,000 000.00","$123","$123 456 789","0.15¢");
foreach($string as $s) {
    echo $s . " = " . toInt($s) . "\n"; 
}
function toInt($str)
{
    return preg_replace("/([^0-9\\.])/i", "", $str);
}
?>

输出

$1,000,000.00 = 1000000.00
$1 000 000.00 = 1000000.00
1,000 000.00 = 1000000.00
$123 = 123
$123 456 789 = 123456789
0.15¢ = 0.15

如果你把它作为一个整数

<?php
$string = array("$1,000,000.00","$1 000 000.00","1,000 000.00","$123","$123 456 789","0.15¢");
foreach($string as $s) {
    echo $s . " = " . _toInt($s) . "\n";    
}
function _toInt($str)
{
    return (int)preg_replace("/([^0-9\\.])/i", "", $str);
}
?>

输出

$1,000,000.00 = 1000000
$1 000 000.00 = 1000000
1,000 000.00 = 1000000
$123 = 123
$123 456 789 = 123456789
0.15¢ = 0

所以你有它.单行,一个替换.你很高兴.

您需要从字符串中删除货币符号.PHP intval在它找到的第一个非数字字符处停止.

$int = intval(preg_replace('/[^\d\.]/', '', '$100')); // 100

虽然如果你有类似的价值$100.25,你可能想要使用floatval.

$float = floatval(preg_replace('/[^\d\.]/', '', '$100.25')); // 100.25
