PHP Date Practice

Creating  a date and  adding a  time interval


<?php

$date = new DateTime();



echo $date->format('Y-m-d H:i:sP') . "<br>";

$date->add(new DateInterval('P30D'));  //adding 30  days



echo $date->format('Y-m-d H:i:sP') . "\n";

Object oriented style

<?php
$date = new DateTime('2000-01-01');$date->add(new DateInterval('P10D'));
echo $date->format('Y-m-d') . "\n";?>

Procedural style

<?php
$date = date_create('2000-01-01');date_add($date, date_interval_create_from_date_string('10 days'));
echo date_format($date, 'Y-m-d');?>

Creating  a  date   using computer time and also specifying time zone

<?php// Specified date/time in your computer's time zone.
$date = new DateTime('2000-01-01');

echo $date->format('Y-m-d H:i:sP') . "\n";

// Specified date/time in the specified time zone.

$date = new DateTime('2000-01-01', new DateTimeZone('Pacific/Nauru'));

echo $date->format('Y-m-d H:i:sP') . "\n";

// Current date/time in your computer's time zone.
$date = new DateTime();

echo $date->format('Y-m-d H:i:sP') . "\n";

// Current date/time in the specified time zone.
$date = new DateTime(null, new DateTimeZone('Pacific/Nauru'));
echo $date->format('Y-m-d H:i:sP') . "\n";

// Using a UNIX timestamp.  Notice the result is in the UTC time zone.
$date = new DateTime('@946684800');
echo $date->format('Y-m-d H:i:sP') . "\n";

printing date and unixtime

$date = date_create();  //create date object based on current date

echo date_format($date, 'Y-m-d H:i:s');  // format and print date

echo "<br>";
echo $date->getTimestamp();  // print the unix time of current date

array callback fuctions

<?php
//////////apply  this  fuction   to  all values of input array 
function cube($n)
{
    return($n * $n * $n);
}

$a = array(1, 2, 3, 4, 5);
$b = array_map("cube", $a);
print_r($b);



code 2

//////////////////////////// return an array  with all values of input array  > 2
function fuv($n)
{

if($n>2) {
return true;
}

}

$c=array_filter($a,"fuv");
