Hi, I have an array containing some user entries which we'd like to load into a database. But the database require us to escape each '\' first. Here is the condition. The number of '\' can vary in each element and the position can be anywhere in the element. I come up with the following piece of code which works if I replace '\' with a random character like '0'. It "duplicates" each 0 with another 0 correctly regardless of how many and where it is. However if I replace it with '\', it failed to make a copy of each backslash. I am not sure what went wrong. Can someone shed some light please?

@row=('aa','bb','\\c\c\','d\d');
$separator=',';
foreach (@row) {
  s/(\\+)/$1$1/g;
}
print join($separator, @row);
print "\n";

Result:
aa,bb,\\\\c\\c\\,d\\d
