Visual Presentation:

$PHP Math Exercises: Convert a date from yyyy-mm-dd to dd-mm-yyyy$

Sample Solution:

PHP Code:

<?php
$odate = "2012-09-12"; // Assign a date string "2012-09-12" to the variable $odate
$newDate = date("d-m-Y", strtotime($odate)); // Convert the date string $odate to a new date format "d-m-Y" using strtotime() and store it in $newDate
echo $newDate."\n"; // Output the new date stored in $newDate followed by a newline character ("\n")
?>

Output:

12-09-2012

Explanation:

In the exercise above,

$odate = "2012-09-12";: This line assigns the date string "2012-09-12" to the variable '$odate'. This string represents September 12, 2012.
$newDate = date("d-m-Y", strtotime($odate));: This line converts the date string $odate to a new date format "d-m-Y" using the "strtotime()" function. The "strtotime()" function parses the date string and returns a Unix timestamp representing the same date and time. The "date()" function formats this timestamp into the specified format "d-m-Y" and stores the result in the variable "$newDate".
echo $newDate."\n";: This line outputs the new date stored in '$newDate', followed by a newline character "\n".
