php xml

https://stackoverflow.com/questions/35223926/class-simplexmlelement-not-found-on-puphpet-php-5-6


The problem was that I was using Cent OS and in this Linux Distribution, the php-libxml package does not come as default.

I ended up generating a new machine through PuPHPet GUI and added to the System Package the following packages to be installed:

php-xml, php-simplexml
Problem solved.

For those using PHP 7 and Ubuntu, @MPS solved it by running apt-get install php7.0-xml and service apache2 restart.


Or  running apt-get install php7.1-xml 
On Centos, we need to install the XML php package. You can try yum install php56w-xml or yum install php70w-xml if you're using php70w repository for PHP 7.0

$arr=array();
$ini=1;
while($ini<=$end) {
$date = new DateTime("2018-04-$ini 03:00");

$timestamp= $date->getTimestamp();
$dayname=getdate($timestamp);
if($dayname['weekday']=='Saturday' or $dayname['weekday']=='Sunday' ){
$date = new DateTime("2018-03-$ini 00:00");

}
$arr[]=$date->format('Y-m-d H:i:s');

//echo $date->format('Y-m-d H:i:s') . "<br><br>";
$ini++;
}


foreach($arr as $key=>$value){
echo "$key=>$value<br>";

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
