标签： regex

我有以下正则表达式：

^((R|AED|AFN|ALL|AMD|ANG|AOA|ARS|AUD|AWG|AZN|BAM|BBD|BDT|BGN|BHD|BIF|BMD|BND|BOB|BRL|BSD|BTN|BWP|BYR|BZD|CAD|CDF|CHF|CLP|CNY|COP|CRC|CUC|CUP|CVE|CZK|DJF|DKK|DOP|DZD|EGP|ERN|ETB|EUR|FJD|FKP|GBP|GEL|GHS|GIP|GMD|GNF|GTQ|GYD|HKD|HNL|HRK|HTG|HUF|IDR|ILS|INR|IQD|IRR|ISK|JMD|JOD|JPY|KES|KGS|KHR|KMF|KPW|KRW|KWD|KYD|KZT|LAK|LBP|LKR|LRD|LSL|LYD|MAD|MDL|MGA|MKD|MMK|MNT|MOP|MRO|MUR|MVR|MWK|MXN|MYR|MZN|NAD|NGN|NIO|NOK|NPR|NZD|OMR|PAB|PEN|PGK|PHP|PKR|PLN|PYG|QAR|RON|RSD|RUB|RWF|SAR|SBD|SCR|SDG|SEK|SGD|SHP|SLL|SOS|SRD|SSP|STD|SYP|SZL|THB|TJS|TMT|TND|TOP|TRY|TTD|TWD|TZS|UAH|UGX|USD|UYU|UZS|VEF|VND|VUV|WST|XAF|XCD|XOF|XPF|YER|ZAR|ZMW) ?([1-9][0-9]{0,2}((,| )?[0-9]{3}){2,}|0)\.[0-9][0-9])?$

它将匹配任何货币值1,000,000或更高。我需要它匹配5,000,000或更高。这似乎应该是一个简单的改变，但我正在与它斗争。

感谢您的帮助。

使用量词的替换

需要解决的正则表达式的片段是匹配范围从1到999的字符类：

[1-9][0-9]{0,2}

将替换标记|与量词{}的第一个参数的增加结合使用，以达到5到999的范围：

([5-9]|[1-9][0-9]{1,2})

enter image description here

可选增强功能：

为简洁起见，您可能还想修改设置为字符类的主要货币标识符：

(R|[A-Z]{3})

同样，您可以使用量词最小化与尾随两位十进制匹配的段：

\.[0-9]{2}

全部放在一起：

((R|[A-Z]{3}) ?([5-9]|[1-9][0-9]{1,2})((,| )?[0-9]{3}){2,})\.[0-9]{2}

保持你的正则表达式。 

preg_match($patter, $string, $out);
$amount = str_replace(",","", $out[2]);

If ($amount>=5000000){
    // code here
}
