    dBase数据库

    dBase数据库是在个人电脑上使用的单机版数据库系统,dBase的系统包括核心数据库引擎、查询系统、表单引擎、与一个脚本编程语言。

    Unfortunately the dbase functions are not compiled into my commercial server's php and I needed to read some geo data in shape files, which include data in dbfs.
    So maybe this will help some others:
    <?php
    function echo_dbf($dbfname) {
        $fdbf = fopen($dbfname,'r');
        $fields = array();
        $buf = fread($fdbf,32);
        $header=unpack( "VRecordCount/vFirstRecord/vRecordLength", substr($buf,4,8));
        echo 'Header: '.json_encode($header).'
    '; $goon = true; $unpackString=''; while ($goon && !feof($fdbf)) { // read fields: $buf = fread($fdbf,32); if (substr($buf,0,1)==chr(13)) {$goon=false;} // end of field list else { $field=unpack( "a11fieldname/A1fieldtype/Voffset/Cfieldlen/Cfielddec", substr($buf,0,18)); echo 'Field: '.json_encode($field).'
    '; $unpackString.="A$field[fieldlen]$field[fieldname]/"; array_push($fields, $field);}} fseek($fdbf, $header['FirstRecord']+1); // move back to the start of the first record (after the field definitions) for ($i=1; $i
