字符串中替换指定部分字符的问题
如果字符串中含有连续数字(14位到19位数字),将连续数字中的倒数第三位至倒数第八位,每一位都替换为一个星号(*)。请问,这个怎么实现?谢了先!


例如:
$str1 = 'test123426789127测试';
//只有12位连续数字,不替换,输出 test123426789127测试

$str2 = '中文736484627347493736';
//替换后输出 中文7364846273******36

$str3 = '号码不是73940128493840571X而是83640148493541398X谢谢!';
//替换后输出 号码不是739401284******71X而是836401484******98X谢谢!
