<?php
#let's say we got following string:
$some_string = '<br />blah blah<br />blah blah<br />';
var_dump(explode('<br />', $some_string));
/* OUTPUT:
array(4) {
[0]=>
string(0) ""
[1]=>
string(9) "blah blah"
[2]=>
string(9) "blah blah"
[3]=>
string(0) ""
}
*/
#So as you see index 0 and index 3 are empty strings. Keep that in mind
