<?php
$con = odbc_connect('ggl_SQL_SERVER','sa','GlobalGuideLine');

$submit_time = "2007-05-29 04:09:49";
$sql = "SELECT 'Posted '"
. " + CONVERT(VARCHAR(40),"
. " DATEDIFF(minute, '$submit_time',"
. " GETDATE())/(24*60))"
. " + ' days, '"
. " + CONVERT(VARCHAR(40),"
. " DATEDIFF(minute, '$submit_time',"
. " GETDATE())%(24*60)/60)"
. " + ' hours, and '"
. " + CONVERT(VARCHAR(40),"
. " DATEDIFF(minute, '$submit_time',"
. " GETDATE())%60)"
. " + ' minutes ago.'";
print(" $sql ");

$res = odbc_exec($con, $sql);
if (!$res) {
print("SQL statement failed with error: ");
print(odbc_error($con).": ".odbc_errormsg($con)." ");
} else {
odbc_fetch_row($res);

If today is you run this script, you will get something like this:

SELECT 'Posted ' + CONVERT(VARCHAR(40),
DATEDIFF(minute, '2007-05-29 04:09:49',
GETDATE())/(24*60))
+ ' days, ' + CONVERT(VARCHAR(40),
DATEDIFF(minute, '2007-05-29 04:09:49',
GETDATE())%(24*60)/60)
+ ' hours, and ' + CONVERT(VARCHAR(40),
DATEDIFF(minute, '2007-05-29 04:09:49',
GETDATE())%60)
