Re^4: How to get array elements from reference ?

I want to print content of the array. I have used following code for that

use TeamSite::WFsystem ;

$system = new TeamSite::WFsystem() ;

@jobs = $system->GetActiveWorkflows();

foreach $job (@jobs){

print "$job \n" ;

}

why am I still getting reference to array printed out ?

Because it seems that `->GetActiveWorkflows` returns an array reference and not an array. Simply assigning to an array does not make the function return an array.	[reply] [d/l]

Since numerous people have told you already that `->GetActiveWorkflows()` returns an arrayref instead of an array, here's the code that does something useful with that: `use TeamSite::WFsystem ; $system = new TeamSite::WFsystem() ; my $ar_jobs = $system->GetActiveWorkflows(); foreach my $job (@{$ar_jobs}){ print "$job \n" ; }` [download] Assuming that `$job` will contain something printable, of course. `@{$ar_jobs}` dereferences the arrayreference, which gives you the array that `$ar_jobs` references to. I usually prefix my arrayref and hashref variables with ar_ and hr_ respectively, so I can easily see what kind of reference I'm dealing with. This is not required, but imo easier to spot.
