PX_TIMESTAMP2STRING(3)													    PX_TIMESTAMP2STRING(3)

px_timestamp2string - Converts the timestamp into a string.

SYNOPSIS

       string px_timestamp2string (resource  $pxdoc, float  $value, string  $format)

DESCRIPTION

	Turns  a  timestamp  as  it  stored in the paradox file into human readable format. Paradox timestamps are the number of miliseconds since
       0001-01-02. This function is just for convenience. It can be easily replaced by some math and the calendar functions as demonstrated in the
       following example.

PARAMETERS

	      o $pxdoc
		- Resource identifier of the paradox database.

	      o $value
		- Value as stored in paradox database field of type PX_FIELD_TIME, or PX_FIELD_TIMESTAMP.

	      o $format
		- String format similar to the format used by date(3). The placeholders support by this function is a subset of those supported by
		date(3) (Y, y, m, n, d, j, H, h, G, g, i, s, A, a, L).

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      Turn a paradox timestamp into a human readable form

	      <?php
	      $px = px_new();

	      /* make up a date as it could be stored in */
	      /* a date field of a paradox db. */
	      /* 700000 days since 1.1.0000. */
	      $days = 700000;

	      /* Use the calendar functions to print a */
	      /* human readable format of the date */
	      echo jdtogregorian($days+1721425)."
";

	      /* Turn it into a timestamp as it stored in a paradox database */
	      /* Timestamps are stored in miliseconds since 0001-01-02 */
	      $stamp = $days * 86400.0 * 1000.0;
	      /* Add one hour */
	      $stamp += 3600000.0;
	      /* The following will output '7/15/1917 01:00:00'. */
	      echo px_timestamp2string($px, $stamp, "n/d/Y H:i:s")."
";

	      px_delete($px);
	      ?>

	      The above example will output:

	      7/15/1917
	      7/15/1917 01:00:00

	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 miliseconds.

PX_INSERT_RECORD(3)													       PX_INSERT_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.
