px_insert_record
(PECL paradox:1.4.0-1.4.1)
px_insert_record — Inserts record into paradox database
Description
int px_insert_record
( resource $pxdoc
, array $data
)
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
midnight. 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
-
pxdoc
-
Resource identifier of the paradox database
as returned by px_new().
-
data
-
Associated or indexed array containing the field values as e.g.
returned by px_retrieve_record().
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; $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; $days -= 1721425; px_insert_record($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, $rec["timestamp"], "n/d/Y H:i:s")."\n";
echo px_date2string($px, $rec["date"], "n/d/Y")."\n";
}
px_close($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()
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.
