php5.6 dbase,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:
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
