px_retrieve_record -- Returns record of paradox database
Description
array px_retrieve_record ( resource pxdoc, int num [, int mode] )
Parameters
pxdoc
Resource identifier of the paradox database
as returned by px_new().
num
The record number is an artificial number counting records in the order
as they are stored in the database. The first record has number 0.
mode
The optional mode can be
PX_KEYTOLOWER or PX_KEYTOUPPER
in order to convert the keys into lower or upper case. If
mode is not passed or is 0, then the key will be
exactly like the field name. The element values will contain the field
values. NULL values will be retained and are different from 0.0, 0 or
the empty string. Fields of type PX_FIELD_TIME
will be returned as an integer counting the number of milliseconds
starting at midnight. A timestamp is a floating point value also
counting milliseconds starting at the beginning of julian calendar.
This function is very similar to px_get_record()
but uses internally a different approach to retrieve the data. It
relies on pxlib for reading each single field value, which usually
results in support for more field types.
Note:
This function is only available if pxlib >= 0.6.0 is used.
Return Values
Returns the num'th record from the paradox
database. The record is returned as an associated array with its keys
being the field names.
