Here are two ways:
<?php
$timeraw = '221216085802';
$datetime = DateTime::createFromFormat('ymdHis', $timeraw);
print $datetime->format('y-m-d H:i:s');
print "\n";
print $timeraw[0] . $timeraw[1] . '-' . $timeraw[2] . $timeraw[3] . '-' .
$timeraw[4] . $timeraw[5] . ' ' . $timeraw[6] . $timeraw[7] . ':' . $timeraw[8]
. $timeraw[9] . ':' . $timeraw[10] . $timeraw[11];

Tēma: How to insert : and - into timestamp string from IoT device?
I have an Arduino IoT device which reads data from an electricity meter and
posts to a website database through a web call to a php script on my webserver.
THis works fine and the timestamp gets into the database as expected.
However it is hard to read so I want to add separators before storing onto the
database.
The timestamp retrieved from the meter looks like this example:
221216085802
It is sent by adding parameter ×tamp=221216085802 to a get call to the php
script.
In php on the webserver before I store it into the database I want to convert it
to a more readable format so it looks like this:
22-12-16 08:58:02
How can I do this in php code?
I.e insert two - one space and two : into the string at given positions
