Question

I’m pushing my values into the array…

while ( ... ) {
  push @array, { label => "label", value => "value" };
}

This appears to be working.

Then…

use JSON::PP ;
print JSON::PP->new->utf8->encode(@array) ; 

only generates…

{"value":"value","label":"label"}

but I need…

[{"value":"value","label":"label"}{"value":"value","label":"label"} etc.. ]

(each item in array outputted, not just the first one…)

Any ideas?

Try passing a reference to the array:

print JSON::PP->new->utf8->encode(\@array) ; 

Encode is documented to take a scalar, not an array (so you need the reference, which is a scalar).
