Im pulling a date from a database which is formatted like dd-mm-YYYY.
What I want to do is check the current date;
This question is related to
php
I have used this one and it served the purpose:
if($date < date("Y-m-d") ) {
echo "Date is in the past";}
BR
Use strtotime to convert any date to unix timestamp and compare.
I wanted to set a specific date so have used this to do stuff before 2nd December 2013
if(mktime(0,0,0,12,2,2013) > strtotime('now')) {
// do stuff
}
The 0,0,0
is midnight, the 12
is the month, the 2
is the day and the 2013
is the year.
a MySQL-only solution would be something like this:
SELECT IF (UNIX_TIMESTAMP(`field`) > UNIX_TIMESTAMP(), `field`,'GO AHEAD') as `yourdate`
FROM `table`
if(strtotime($db_date) > time()) {
echo $db_date;
} else {
echo 'go ahead';
}
if (strtotime($date) > mktime(0,0,0))
should do the job.
if(strtotime($row['database_date']) > strtotime('now')) echo $row['database_date'];
else echo date("d-m-Y");
No need to check the hours because if they are on the same day it will show the same date either way...
If you are looking for a generic way of doing this via MySQL, you could simply use a SELECT
statement, and add the WHERE
clause to it.
This will grab all fields for all rows, where the date stored in field "date" is before "now".
SELECT * FROM table WHERE UNIX_TIMESTAMP(`date`) < UNIX_TIMESTAMP()
Personally, I found this method to be more gentle on newbies in MySQL, since it uses the standard SELECT statement with WHERE to fetch the results. Obviously, you could grab only the fields relevant if you wanted to, by listing them instead of using a wildcard (*).
Here's a list of all possible checks for …
"Did a date pass?"
$date = strtotime( $date );
$date > date( "U" )
$date > mktime( 0, 0, 0 )
$date > strtotime( 'now' )
$date > time()
$date > abs( intval( $_SERVER['REQUEST_TIME'] ) )
I did some performance test on 1.000.000 iterations and calculated the average – Ordered fastest to slowest.
+---------------------+---------------+
| method | time |
+---------------------+---------------+
| time() | 0.0000006732 |
| $_SERVER | 0.0000009131 |
| date("U") | 0.0000028951 |
| mktime(0,0,0) | 0.000003906 |
| strtotime("now") | 0.0000045032 |
| new DateTime("now") | 0.0000053365 |

ProTip: You can easily remember what's fastest by simply looking at the length of the function. The longer, the slower the function is.
The following loop was run for each of the above mentioned possibilities. I converted the values to non-scientific notation for easier readability.
$loops = 1000000;
$start = microtime( true );
for ( $i = 0; $i < $loops; $i++ )
date( "U" );
printf(
'| date("U") | %s |'."\n",
rtrim( sprintf( '%.10F', ( microtime( true ) - $start ) / $loops ), '0' )
);
time()
still seems to be the fastest.
