PHP caveats – int/float type conversion

The following code checks various scenarios in which inbuilt functions like intval, floatval, is_numeric, is_float and filter_var would result for several different types of values. Feel free to run in your local, leave comments if I can make the results more interesting with some more functions.

Jenkins auto deploying flask in test env with last build process kill and pipenv

This unique date 02 02 2020 will come after 1010 years – WRONG MATH

In dd/mm/yyyy format, 2nd February 2020 (02 02 2020) is a palindrome

In really common beliefs, whatsapp forwards were filled with this number being so rare and unique. However it would be stupid to say that such a rare date will occur only after 1010 years.

Here is how:

In whole millennium (1000 years), first few years of first few centuries have many of such dates. Even if you consider MM/DD/YYYY format, you can find a lot of such numbers in first few centuries.

Here are all of such dates in this century (2000 – 2099) in DD/MM/YYYY format
