converting a string to date in php - php

Question

I have a string that contains date and time. Format of my string is yyyymmddtime.
For example. 20171125123000209. this is my complete string in which first comes the month, then month and then day after that time. How can i retrieve date from it by converting to readable date format. I tried with php's date function. But the output was not as expected. Please help.

Answer 1

Try this
<?php
$str_date= "20171125123000209";
$exiting_date_format='Ymd';
//first 8 characters from given date string in second parameter below
$date = DateTime::createFromFormat($exiting_date_format, substr($str_date,0,8));
echo $date->format('Y-m-d');//specify desired date format
?>
Output :
2017-11-25
DateTime::createFromFormat - Parses a time string according to a specified format

Answer 2

You can use date() function of php
<?php
$full_date= "20171125123000209";
echo date('dS F h:i:s A', $full_date);
//Output = 31st May 12:30:09 AM
?>
Or,
To get date from timestamp like now,
$timestamp= time(); //Or your timestamp here
$date = date('d-m-Y', $timestamp); //Inside first parameter, give your date format
echo $date; //17-12-2017
Or,
To get anything from string you can also use substr() function of php.
<?php
$full_date= "20171125123000209";
$year = substr($full_date, 0, 4);
$month = substr($full_date, 4, 2);
$date = substr($full_date, 6, 2);
echo 'Year = '.$year.' ';
echo 'Month = '.$month.' ';
echo 'Date = '. $date.' ';
?>
Output:
Year = 2017 Month = 11 Date = 25

Answer 3

It's not necessary to manipulate the string at all. PHP's DateTime class supports parsing a string containing miliseconds natively, using the u format modifier:
$str = '20171125123000209';
$date = DateTime::createFromFormat('YmdHisu', $str);
Using your new $date object, you can convert to whatever format you're looking for, e.g.
echo $date->format("F j Y, g:i a");

$your_strtotime_val = ""; //20171125123000209
$convert_to_date = date("m-d-Y h:i:s",$your_strtotime); // [m-d-Y h:i:s] this depending on how you convert date in first time so be careful
