my $array_ref = {}; push(@$array_ref, {});
The code above, which is part of your second example, gives an error because $array_ref = {} initializes your $array_ref to a hash ref which is not compatible as the first argument of push. It may be sort of symptomatic of your programming difficulties in that initializing $array_ref to a hash ref is confusing and just looks like code that is headed off in the wrong direction. I think your examples add more complication than needed and, for me, trying to simplify gives a result like:
use strict; use warnings; sub foo { my %hash = (); .... %hash = .... # key/values populated by some API bar(\%hash); } sub bar { my $hash_ref = shift; my @arr_of_href = $hash_ref; foreach my $i (.....) { .... %some_hash initialized here for each iteration of the for + loop push (@arr_of_href, \%some_hash); } zzz(\@arr_of_href); # zzz() will do something with this array }

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
