How to Convert 'yyyy-mm-dd' to 'dd-mm-yyyy' Date Format in PHP Without Using SQL?

Convert a Date Format in PHP

You may encounter a scenario where you need to reformat a date from yyyy-mm-dd to dd-mm-yyyy without using SQL. However, the date function in PHP typically requires a timestamp, and extracting a timestamp from a string can be challenging.

To overcome this hurdle, you can utilize the following approach:

use DateTime;
use DateTimeZone;

$originalDate = "2010-03-21";
$timestamp = strtotime($originalDate); // Convert to a timestamp

// Option 1: Using DateTime
$dt = new DateTime();
$dt->setTimestamp($timestamp);
$newDate = $dt->format('d-m-Y'); // Reformat the date

// Option 2: Using date() with strtotime()
$newDate = date("d-m-Y", $timestamp);

The strtotime() function converts the string representation of the date into a timestamp. Subsequently, you can use either DateTime or date() to reformat the date according to your desired format.

Note:

While this approach provides a simple solution, it might not be suitable for all conversion scenarios. For more complex date conversions, consider using the DateTime class for parsing and formatting.
