String eval is bad mojo. What you really need is either a template
module* (if your needs are very complex) or a simple substitution (if
you needs are simple).
#!/usr/bin/perl
use strict;
use warnings;
my $project_path_template = "/foo/bar/{PROJECT}/here";
for my $project (qw/project1 project2 project3/) {
(my $project_path = $project_path_template) =~ s/\{PROJECT\}/$project/;
print "the project path is $project_path\n";
}
* Search CPAN for template modules until you find one with the
features you want, this one looks fairly close to what you want:
