RE: [PHP-DB] substr() problems

[James Meers]

Apologies, the script was right - but the data was wrong - I had lots of white space 
at the end of each string, i have used rtrim to solve this:
 
$DB_ref = rtrim($DB_ref," ");

$DB_temp_ref = $DB_ref;

        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?

        Many thanks in advance,
