How to determine if an element exists in a Perl array

#!/usr/bin/perl

my @testArray = qw(apple apple1 apple2 banana);

my $testElement1 = "apple1";

my $testElement2 = "banana";

my $Counter = 0; my %testHash = {};

%testHash = map { $_ => $Counter++} @testArray;

print "Test element 1 exists!\n" if (exists $testHash{$testElement1});

print "Test element 2 exists!\n" if (exists $testHash{$testElement2});

Mysql Issue

Yesterday I installed Mysql on my laptop. After running mysqld_safe it always gave me the same error information:

wipa-43-181:~ ZHENGFU$ mysqladmin version
/usr/local/mysql/bin/mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)'
Check that mysqld is running and that the socket: '/tmp/mysql.sock' exists!

Seems like the mysql server did not start so the socket file was not created. Does anyone know how to figure it out?
