[SOLVED] time() function help please

[elmas156]

I'm trying to get a unix timestamp of a previous date and the current date so that I can compare them in a script that I'm writing.  I've tried the following code in several variations but the output for the $now and $then variables are always the same, which is the current unix timestamp.  What am I doing wrong?

 

Here's my code:

<?php
$apptdate="2008-09-20";

$now = time();
$then = time("$apptdate");

echo "$now<br>";
echo "$then";
?>

[jonsjava]

try this:

<?php
$apptdate="2008-09-20";

$now = time();
$then = time() - 86400; //current time minus 1 day

echo "$now<br>";
echo "$then";
?>

...jonsjava, that doesn't use $apptdate though. =/

 

Try:

 

<?php
$apptdate="2008-09-20";

$now = time();
$then = strtotime($apptdate);

echo "$now<br>";
echo "$then";
?>

doh! didn't read his post correctly.

that works for $then but now how do I get the timestamp for the current date at exactly midnight?  I need this so I can  do something like this:

 

<?php

if ($then == $now - 7776000) { // if $then is 90 days ago

send a reminder email

}

$midnight = strtotime('midnight');

 

I love strtotime().

GREAT! Thanks.

Slightly faster

 

mktime(23,59,59)

 

Technically, 24:00:00 is 00:00:00 of the next day. if you want that just use

 

mktime(24,0,0)

strtotime() makes the world go 'round though... =(

[elmas156]

One more question... how do I take the timestamp and convert it back to a normal date?

 

convert

 

1222326000

 

to

 

2008-09-24

[DarkWater]

$date = date('Y-m-d', $timestamp);
