PHP Date Format Conversion: dd/mm/yyyy to yyyy-mm-dd

Converting date formats between dd/mm/yyyy and yyyy-mm-dd can be challenging in PHP.

Issue:
The primary issue arises when working with dates in the dd/mm/yyyy format. Due to the ambiguity created by the slash separator (/), PHP often assumes the American m/d/y format instead of the European d-m-y.

Solution:
To overcome this issue, there are two approaches you can consider:

1. Using the Default Date Function:

   • This approach involves using the strtotime() function to convert the string date to a timestamp and then using the date() function to format the timestamp in the desired format.
   • However, it's important to note that PHP may not handle the dd/mm/yyyy format accurately.

2. Custom Formatting with Str_Replace:

   • This alternative approach involves using the str_replace() function to manually replace the slash separators with dashes before converting the string date to a timestamp.
   • This method ensures that the date is interpreted correctly as a European d-m-y format.
