如何从带有其他逗号的字符串中的数值中删除逗号？

Question

我正在使用一个包含账户报表的数组。我希望能够从数值中删除逗号，以便能够在不丢失重要值的情况下用逗号展开。

例如，我的数组包含如下索引：

26 => 20/08/2099,"ATM CASH WITHDRAWAL (ON-US) ATM CASH WITHDRAWAL (ON-US) EMPEMOM, LAGA ATM 2 LOGO NG 000360585490","",20/08/2018,"5,000","","1,316.01"

27 => 27/08/2027,BANK CHARGE 26 SMS CHARGE AND VAT FOR 27TH JUL - 23RD AUG 2018,2803064 028,27/08/2018,109.2,"","1,206.81"

我想在不删除每个字符串之间的逗号的情况下删除“5,000”和其他货币值中的逗号，以便输出如下所示：

26 => 20/08/2099,"ATM CASH WITHDRAWAL (ON-US) ATM CASH WITHDRAWAL (ON-US) EMPEMOM, LAGA ATM 2 LOGO NG 000360585490","",20/08/2018,"5000","","1316.01"

27 => 27/08/2027,BANK CHARGE 26 SMS CHARGE AND VAT FOR 27TH JUL - 23RD AUG 2018,2803064 028,27/08/2018,109.2,"","1206.81"

Answer 1

你可以使用 foreach 你的数组并用逗号展开然后替换“，”每个数组然后检查它是否是数字

foreach 数组然后用逗号分解字符串

$stringArray=explode(",",$str)

然后替换“,”每个 $stringArray

$CheckNumber= str_replace(',', '', $string);

并通过以下方式检查它是否为数字：

if (is_numeric($CheckNumber))
   $stringArray[i]=$CheckNumber;

最后加入数组

join(",",$stringArray);

Answer 2

您也可以使用 array_map with preg_replace_callback 作为模式，您可以使用：

"\d{1,3}(?:,\d{3})+\.\d{2}"

"\d{1,3} 匹配 " 后跟 1-3 位数字
(?:,\d{3})! 重复 1+ 次匹配一个逗号和 3 个数字
\.\d{2}" 匹配一个点和 2 个数字后跟 "

在 preg_replace_callback 的回调中，将逗号替换为空字符串并 return 匹配。

例如：

$atm = array(
    '26' => '20/08/2099,"ATM CASH WITHDRAWAL (ON-US) ATM CASH WITHDRAWAL (ON-US) EMPEMOM, LAGA ATM 2 LOGO NG 000360585490","",20/08/2018,"5,000","","1,316.01"',
    '27' => '27/08/2027,BANK CHARGE 26 SMS CHARGE AND VAT FOR 27TH JUL - 23RD AUG 2018,2803064 028,27/08/2018,109.2,"","1,206.81"'
);

$atm = array_map(function($x) {
    return preg_replace_callback('/"\d{1,3}(?:,\d{3})+\.\d{2}"/', function($m) {
       return  str_replace(',', '', $m[0]);
    }, $x);
}, $atm);

print_r($atm);

结果：

Array
(
    [26] => 20/08/2099,"ATM CASH WITHDRAWAL (ON-US) ATM CASH WITHDRAWAL (ON-US) EMPEMOM, LAGA ATM 2 LOGO NG 000360585490","",20/08/2018,"5,000","","1316.01"
    [27] => 27/08/2027,BANK CHARGE 26 SMS CHARGE AND VAT FOR 27TH JUL - 23RD AUG 2018,2803064 028,27/08/2018,109.2,"","1206.81"
)
