I use the following procedure to recode records that are read in from a dbase file. If I run this script for all the 3500 records in the dbase file the apache server process uses 150MB of memory.



function recodeDBF($dbfin) {

$dbfout=array();

while( list($key, $inval) = each($dbfin) ) {
    $dbfout[$key]=recode_string("pc..l1",trim($inval)); // A LOT OF MEMORY
    // $dbfout[$key]=trim($inval); // NORMAL MEMORY USAGE
    }
    return $dbfout;
}
