You could:

use strict;
use warnings;

my $tempStr = <<'STR';
sdfasdfsdfsd
asdfasdfasdfasdfsdfsd
...
is_raw_sql_editor = FALSE"
STR

open my $inFile, '<', \$tempStr;
local $/ = "\n\n"; # Break input into paragraphs

while (<$inFile>) {
    chomp;
    next unless length;
    next unless /
        User\s+(\w+).*?
        phone\s*=\s*(\w*).*?
        email\s*=\s*(\w*).*?
        misc_info\s*=\s*(.*)
        /xs;
        
    print "User $1, phone $2, email $3, misc_info:\n$4\n\n";
}
[download]

Prints:

User soandso, phone , email a, misc_info:
is_superuser = TRUE
is_appbuilder = TRUE
is_packagehacker = FALSE
is_user_maint = TRUE
authentication = CQ
is_dynamic_list_admin = FALSE
is_public_folder_admin = FALSE
is_security_admin = FALSE
is_raw_sql_editor = FALSE

User soandso1, phone , email a, misc_info:
is_superuser = TRUE
is_appbuilder = TRUE
is_packagehacker = FALSE
is_user_maint = TRUE
authentication = CQ
is_dynamic_list_admin = FALSE
is_public_folder_admin = FALSE
is_security_admin = FALSE
is_raw_sql_editor = FALSE"
[download]

which scales nicely to obtaining the input from a file.
