remove an element of an array

[j0nxuser]

Need some assistance with an array. For example, I have an array of unique email addresses (thanks to Getopt::Long) and need to send emails to every address in that array via a for loop. That said, before I enter the for loop to send the emails I need to check to see if the email address joe.q.public@anywhere.com exists. If this email address exists I'll need to delete it from the array and then send the email to everyone else in the array.

Is there a remove function? Exists will just tell if something exists, correct? (I want to remove it entirely)

Very simplied version of my array:
@email_addresses = ('joe@schmoe.com','jane@schmoe.com','joe.q.public@anywhere.com');

Use a hash instead of an array: the keys will be the email addresses, the values anything you like.
Then it will be just a matter of [tt]delete $email_addresses{'joe.q.public@anywhere.com'}[/tt] (you even don't need to check for existence before).
Then you send to [tt]keys%email_addresses[/tt] .

In case you ever get into a scenario where all you have is an array - check out the 'splice' function.
