convert time format

meshi · 12-10-2007, 09:46 AM

hi guyz i need ur help!!

how could i convert the time format for example i have a time 4:56 pm and i want to convert it in 16:56 so that the if i query it from the database it displays the result.?

on more thing how would i iterate in this format

00
01
02
03
04
05
06
07
08
09
if i use this:
for (i=0;i>10;i++)

the result would be
123456789

how would i put 0's in my iteration so that it would be 2 numbers?

Copied from Kohana's date helper:

PHP Code:


			
    /**

     * Adjusts a non-24-hour number into a 24-hour number.

     *

     * @param   integer  hour to adjust

     * @param   string   AM or PM

     * @return  string

     */

    public static function adjust($hour, $ampm)

    {

        $hour = (int) $hour;

        $ampm = strtolower($ampm);



        switch($ampm)

        {

            case 'am':

                if ($hour == 12)

                    $hour = 0;

            break;

            case 'pm':

                if ($hour < 12)

                    $hour += 12;

            break;

        }



        return sprintf('%02s', $hour);

    }

As you can see, you can use sprintf to autofill a number with zeroes.

foreach(range(1, 200) as $iInteger)
{
    sprintf("%02d", $iInteger);

Haris is on fire today I see

! Very nice Haris, kudos for that!

meshi · 12-10-2007, 11:01 AM

thanks guyz..

Is there any reason you take the longer approach, Geert?

Regarding echo sprintf, what's that all about? Also, there is no need in this case for double quotes around the formatting string. I'm sure this isn't the first time I've seen echo sprintf posted up here, so every time I see it, I'll keep nagging!

php Code:

foreach (range(1, 200) as $iInteger)
{
    printf('%02d', $iInteger);
}

I've never found a reason to use double quotes yet.. have you?

Some people like to do

PHP Code:


			
$foo = "Welcome, {$bar}.";

However if you have ever bench-marked the concatenation speed of that, and compare it to the speed of

PHP Code:


			
$foo = 'Welcome, ' . $bar;

You will find that the single-quote concatenation is faster

Why don't you just use a unix timestamp? You can output that in any formate with the date() function.

The PHP document inspired me to use the echo.

I was bitten by the overlong function snake.

Lol! I can see those monsters playing a big part in this community

I'm sure we all have a few of those monsters in our code.

I've never had a need for double quotes except when using \r and \n.

Good point. I've only been using it in javascript (for popups and ofcourse alerts/confirms). Next to that, can't recall where I used it. Oh, I used it for

PHP Code:


			
$rSql = 'SELECT * FROM prefix_table WHERE username LIKE "%$user%"'

That's allowed since it is the sprintf documentation page.
