逗号分隔的列表到 PHP 中的非关联数组

Question

I have a string of emails:

$emails = 'email1@example.com, email2@example.com,email3@example.com';

and I need a basic array like [one,two,three] and not [0 => 'one', 1 => 'two', 2 => 'three'] . I guess is a non-associative array?

How to do that? I have tried the inbuild 'explode()' PHP function but it creates 0 => one, ... instad of aa simple array email1,email2,..

Besides, explode has problem when there is a space after the comma, so I have to use ', ' or ',' but can't use both.

What PHP function is the best to convert a list of email addresses into a simple non-associative array? Thanks in advance.

Answer 1

First you can remove spaces by str_replace

$emails = str_replace(' ', '', $emails);

and I need a basic array like [one,two,three] and not [0 => 'one', 1 => 'two', 2 => 'three']. I guess is a non-associative arr

In php simple arrays has numeric keys, so it's correct
