PX_GET_INFO(3)															    PX_GET_INFO(3)

px_get_info - Return lots of information about a paradox file

SYNOPSIS

       array px_get_info (resource  $pxdoc)

DESCRIPTION

PARAMETERS

	      o $pxdoc
		- Resource identifier of the paradox database as returned by px_new(3).

RETURN VALUES

	Returns an associated array with lots of information about a paradox file. This array is likely to be extended in the future.

	      o fileversion
		-Version of file multiplied by 10, e.g. 70.

	      o tablename
		-Name  of  table  as  stored in the file. If the database was created by pxlib, then this will be the name of the file without the
		extension.

	      o numrecords
		-Number of records in this table.

	      o numfields
		-Number of fields in this table.

	      o headersize
		-Number of bytes used for the header. This is usually 0x800.

	      o recordsize
		-Number of bytes used for each record. This is the sum of all field sizes (available since version 1.4.2).

	      o maxtablesize
		- This value multiplied by 0x400 is the size of a data block in bytes. The maximum number of records in a datablock is the integer
		part of (maxtablesize * 0x400 - 8) / recordsize.

	      o numdatablocks
		- The number of data blocks in the file. Each data block contains a certain number of records which depends on the record size and
		the data block size (maxtablesize). Data blocks may not necessarily be completely filled.

	      o numindexfields
		- Number of fields used for the primary index. The fields do always start with field number 1.

	      o codepage
		- The DOS codepage which was used for encoding fields with character data. If the target encoding is not set with px_set_targeten-
		coding(3)   this  will	be  the  encoding  for	character  fields  when  records  are  being  accessed	with  px_get_record(3)	or
		px_retrieve_record(3).

px_insert_record - Inserts record into paradox database

SYNOPSIS

       int px_insert_record (resource  $pxdoc, array  $data)

DESCRIPTION

	Inserts  a  new  record  into  the database. The record is not necessarily inserted at the end of the database, but may be inserted at any
       position depending on where the first free slot is found.

	The record data is passed as an array of field values. The elements in the array must correspond to the fields in  the	database.  If  the
       array has less elements than fields in the database, the remaining fields will be set to null.

	Most  field values can be passed as its equivalent php type e.g. a long value is used for fields of type PX_FIELD_LONG, PX_FIELD_SHORT and
       PX_FIELD_AUTOINC, a double values is used for fields of type PX_FIELD_CURRENCY and PX_FIELD_NUMBER. Field values for blob and alpha  fields
       are passed as strings.

	Fields	of type PX_FIELD_TIME and PX_FIELD_DATE both require a long value. In the first case this is the number of milliseconds since mid-
       night. In the second case this is the number of days since 1.1.0000. Below there are two examples to convert the current date or  timestamp
       into a value suitable for one of paradox's date/time fields.

       Note

	       This function is only available if pxlib >= 0.6.0 is used.

PARAMETERS

	      o $pxdoc
		- Resource identifier of the paradox database as returned by px_new(3).

	      o $data
		- Associated or indexed array containing the field values as e.g. returned by px_retrieve_record(3).

RETURN VALUES

	Returns FALSE on failure or the record number in case of success.

EXAMPLES

       Example #1

	      Set the date/time fields in a paradox database to the current date/time

	      <?php
	      $px = px_new();
	      $fp = fopen("test.db", "w+");
	      px_create_fp($px, $fp, array(array("timestamp", "@"), array("time", "T"), array("date", "D")));

	      $curdate = getdate();
	      $jd = gregoriantojd($curdate["mon"], $curdate["mday"], $curdate["year"]);
	      $days = $jd - 1721425; /* Number of days between 1.1.4714 b.c. and 1.1.0000 */
	      $secs = $curdate["hours"]*3600 + $curdate["minutes"]*60 + $curdate["seconds"];
	      px_insert_record($px, array($days*86400000.0 + $secs*1000.0, $secs*1000.0, $days));

	      $curtimestamp = microtime(true);
	      $days = (int) ($curtimestamp/86400);
	      $secs = $curtimestamp - ($days * 86400.0);
	      $days += 2440588; /* Number of days between 1.1.4714 b.c. and 1.1.1970 */
	      $days -= 1721425; /* Number of days between 1.1.4714 b.c. and 1.1.0000 */
	      px_insert_record($px, array($days*86400000.0 + $secs*1000.0, $secs*1000.0, $days));
	      for($i=0; $i<2; $i++) {
		  $rec = px_retrieve_record($px, $i);
		  echo px_timestamp2string($px, $rec["timestamp"], "n/d/Y H:i:s")."
";
		  echo px_date2string($px, $rec["date"], "n/d/Y")."
";
	      }
	      px_close($px);
	      px_delete($px);
	      ?>

	      The above example will output:

	      2/21/2006 21:42:30
	      2/21/2006
	      2/21/2006 20:42:30
	      2/21/2006

	The  Julian  day  count  as  passed  to  jdtogregorian(3) has a different base of 1.1.4714 b.c. and must therefore be calculated by adding
       1721425 to the day count used in the paradox file. Turning the day count into a timestamp is easily done by multiplying with 86400000.0	to
       obtain milli seconds.
