How to split time value in PHP? - php

Question

I have these time value from HTML form using timepicker js.
I want to split the value into three (3) variables which is $hour, $minute and $period.
The problem is I can't split 'AM' or 'PM' value into another variable.
$minute hold the value "00 PM". I want AM or PM store into another variable call $period
What I have done so far as code below.
Time.php
<?php
// $btArray = explode(':', $_POST['app_time']);
$btArray = explode(':', '11:00 PM');
$hour = strlen(trim($btArray[0])) > 1 ? trim($btArray[0]) : '0' . trim($btArray[0]);
$minute = trim($btArray[1]);
$period = trim($btArray[2]);
$query = "UPDATE TABLE
SET
BOOK_TIME = '" . $hour . ":" . $minute . "',
TIME_PERIOD = '" . $period ."'
WHERE
TRACK_NUM = ''
";
?>
My goal is to split the value so I can store it into database.
Appreciate if someone can help me to solve this problem.
Thanks.

Answer 1

$btArray= "7:00 am";
preg_match("/([0-9]{1,2}):([0-9]{1,2}) ([a-zA-Z]+)/", $btArray, $match);
$hour = $match[1];
$min = $match[2];
$period = $match[3];
$query = "UPDATE TABLE
SET
BOOK_TIME = '" . $hour . ":" . $minute . "',
TIME_PERIOD = '" . $period ."'
WHERE
TRACK_NUM = ''
";

Answer 2

Try this,
$time = '11:00 PM';
//first remove right two char
$period = substr($time, -2, 2);
//remove that string from main string
$newTime = str_replace($period, "", $time);
//convert remaining string to array
$btArray = explode(':', $newTime);
//check hour string length and concate 0
$hour = (strlen($btArray[0]) > 1) ? $btArray[0] : '0'.$btArray[0];
$mint = $btArray[1];
echo $hour.'<pre>';
echo $mint.'<pre>';
echo $period.'<pre>';
die;
Output:
11
00
PM

Answer 3

I would rather suggest to use substr() function as the parameters like: hour, minute, seconds are fixed.
First need to check whether the string length of 8.
Then, get parameters depending upon their positions.
If your date format is constant.
<?php
$str = '11:00 PM';
if (strlen($str) == 8) {
$hour = substr($str, 0, 2);
$minute = substr($str, 3, 2);
$period = substr($str, 6, 2);
}
echo '<pre>';print_r('Hour: '. $hour);echo '</pre>';
echo '<pre>';print_r('Minute: '. $minute);echo '</pre>';
echo '<pre>';print_r('AM/PM: '. $period);echo '</pre>';
Output:
Hour: 11
Minute: 00
AM/PM: PM

You can try below code for your desire output.
$btArray = explode(':', '11:00 PM');
$hour = strlen(trim($btArray[0])) > 1 ? trim($btArray[0]) : '0' . trim($btArray[0]);
$minute_period_array = explode(' ', $btArray[1]);
$minute = trim($minute_period_array[0]);
$period = trim($minute_period_array[1]);
echo 'Hour - ' . $hour . '<br/>';
echo 'Minute - ' . $minute . '<br/>';
echo 'Period - ' . $period . '<br/>';
Output :
Hour - 11
Minute - 00
Period - PM

Answer 5

If you will get the input value always in the same format, you can go this way:
$input = '8:05 PM';
list($hour, $minute, $period) = explode(' ', str_replace(':', ' ', $input), 3);
// And then clean the variables
$hour = str_pad($hour, 2, '0', STR_PAD_LEFT);
$minute = str_pad($minute, 2, '0', STR_PAD_LEFT);
$period = strtoupper(trim($period));
// $hour -> 08, $minute -> 05, $period -> PM
