px_retrieve_record
(PECL paradox >= 1.4.0)
px_retrieve_record — Returns record of paradox database
설명
$pxdoc
, int $num
[, int $mode = 0
] )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.
