485740 php4 to php5 issue

We have just recompiled our server from php4 to php5 and getting an error: Fatal error: Cannot use string offset as an array in /home/xxx/[login to view URL] on line 146 That file has the following code at that line: return strtoupper($fMemb[ login ][ 0 ]).str_repeat("0", 6 - strlen($fMemb[ id ])).$fMemb[ id ]; } The code above this line is below: -------------------------------------------------------- function sysGetProfileCode($fMemb = 1) { global $fMember; if($fMemb == 1) { $fMemb = $fMember; } return strtoupper($fMemb[ login ][ 0 ]).str_repeat("0", 6 - strlen($fMemb[ id ])).$fMemb[ id ]; } // sysGetProfileCode ----------------------------------------------------------------- We need a fix to get this code working on the new PHP5.
