What is the proper way to check if a string is empty in Perl?
comparison, perl, string
Solution
For string comparisons in Perl, use `eq` or `ne`:
if ($str eq "")
{
// ...
}
The `==` and `!=` operators are numeric comparison operators. They will attempt to convert both operands to integers before comparing them.
See the perlop man page for more information.
Problem
I have been using this code to check if a string is empty: ``` if ($str == "") { // ... } ``` And also the opposite with the not equals operator... ``` if ($str != "") { // ... } ``` This seems to work (I think), but I'm not sure it's the correct way, or if there are any unforeseen drawbacks. Something just doesn't feel right about it.
