The optional <code class="parameter">mode</code> can be

|
<strong><code>PX_KEYTOLOWER</code></strong> or <strong><code>PX_KEYTOUPPER</code></strong>
|
|
in order to convert the keys of the returned array into lower or
|

upper case. If
|

<code class="parameter">mode</code> 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 <strong><code>PX_FIELD_TIME</code></strong>
|
|
will be returned as an integer counting the number of milliseconds
|
|
starting at midnight. A timestamp
|
|
(<strong><code>PX_FIELD_TIMESTAMP</code></strong>) and date
|
|
(<strong><code>PX_FIELD_DATE</code></strong>) are floating point respectively
|
|
int values counting milliseconds respectively days starting
|

at the beginning of julian calendar.

<span class="function"><a href="px_date2string.html" class="function">px-date2string()</a></span> to convert them into a character
