Question

here is the code first

$sql = 'SELECT DATETIME, CURRVALUE FROM DATEVALUE';
$stid = oci_parse($conn, $sql);
oci_define_by_name($stid,'DATETIME', $agev);
oci_define_by_name($stid,  'CURRVALUE', $snv);
oci_execute($stid);
$resultXML = new SimpleXMLElement(stripslashes('<data></data>'));
while (oci_fetch($stid)) {  
      $agev = oci_result($stid, 'DATETIME');
    $snv = oci_result($stid, 'CURRVALUE');
     //settype($agev, "string"); 
    $date_2 = strtotime($agev);
    settype($date_2, "integer"); 
     //settype($snv, "float");  
    $temp = $resultXML->addChild('node'); 
    $temp->addChild('agev',$date_2);
    $temp->addChild('snv',$snv); 
} 

<node>
<agev>0</agev>
<snv>1</snv>
</node>

result for currvalue is good but for datetime value it output zero only,
if i do addtimevalue without using strtotime it will output datetime in string but its not what i need….
please helppppp ~.~

Answer 1

Here are two ways that could help fix the problem.

First (possibly better) way: Change your SQL query.

Have Oracle output the date using a different format, one that strtotime will recognize. If DATETIME is a normal date-type column in your database, consider using the TO_CHAR Oracle function to change its output format. Something like:

$sql = "SELECT TO_CHAR(DATETIME, 'YYYY-MM-DD HH24:MI:SS') AS DATETIME, CURRVALUE FROM DATEVALUE";

Second way: use strptime.

Instead of using strtotime, consider using strptime. The date format you show in your comments appears to be close to:

%d-%b-%y %H.%I.%S %p

I’m not sure if there’s a date format option for the milliseconds part. Assuming it will parse it correctly without that, changing the line:

$date_2 = strtotime($agev);

to:

$date_2 = strptime($agev, '%d-%b-%y %H.%I.%S %p');

should do it. You’ll still get an error, though, if my assumption is wrong.
