Hi all,
I am trying to use substr() negative start, but I get nothing returned - if i do a positive start
then i do get something back, below is my code and a line of what i get returned:
$DB_ref = "210020007";
$DB_temp_ref = $DB_ref;
$DB_sub_ref = substr($DB_temp_ref , 0, 1);
$DB_sub_ref .= substr($DB_temp_ref , 1, 1);
$DB_sub_ref .= substr($DB_temp_ref , -1, 1);
echo "$DB_sub_ref - $DB_ref";
RESULT:
"21 - 210020007"
note: 210020007 is an example this is actually within a while statement using mysql_fetch_array from
a SQL query - all results are not returning the negative string.
Can anyone help?
PHP Version 4.3.3
Apache/2.0.47 (Fedora)
Many thanks in advance,
James.
