While converting timestamp to data, the format is required, in PHP, we have some method, or we can say functions which do this conversion for us; we just need to mention the timestamp there to get the data.
This timestamp is a long integer value representing the data and time for the data as the name suggests; it consists of data and the time, so at the time of converting the timestamp, we can also get the time from it. Here we will see the method definition and the required parameter needed while dealing with the timestamp in PHP. We will also see its implementation and usage in detail for better understating. Start Your Free Software Development Course. As you can see in the above syntax, this is the syntax given by the PHP official documentation for timestamp, which requires two parameters here to convert the timestamp to date in PHP.
As of now, we already know that how we can get the data object from the timestamp integer in PHP. For this, we have to have a format in place that will help us get the date from the timestamp, here we will first see the method signature for timestamp, and then we will see how we can implement this in our program with step by step guide. Method Signature: We have one method which is provided by the PHP only; it is an inbuilt method from the PHP library, and to use this, we do not require to add an external library; also, we do not require to have any import statement as well.
As you can see, this is an official declaration of this method which we can use to convert the timestamp object to date. But here, we have two parameters: the format and the other is timestamp. We can pass null as the value for this field; if we do so, it will calculate the data object based on the current timestamp, but if we pass any value here, it will give us the value based on it only. We may require showing value to users that they can understand so that we can convert the timestamp object to date; after that, it can be readable and under stable by others to show to the client.
This function is easy to use and handle also do not require any dependency from the other things. So we can use this to get the date from the timestamp easily. This is a guide to Timestamp to Date in PHP. Here we discuss the introduction, how to convert timestamp to date in PHP? We can easily handle epoch or Unix timestamp to convert into human readable dates or can convert human readable dates to Unix timestamp.
We can get the current epoch or timestamp using PHP time function. The function returns the current epoch in the number of seconds. We can convert the epoch or timestamp to readable date format using PHP date function.
The function formats and return epoch or timestamp to human readable date and time. we can also convert epoch or Unix timestamp to formatted date using PHP DateTime class. We can convert human readable date to timestamp using PHP strtotime function.

How is it that you have not gotten the credit for this answer yet?! A completely valid answer, but I'm surprised that Armin Ronacher's answer hasn't matched it in upvotes -- ambiguity is ALWAYS bad. Devner Well, it seems, on my server, that format isn't supported. Maybe it's different with yours. LucaFagioli It seems Prof. Falken, desperate to see that answer with so many upvotes, updated it and included his own science.

I'd recommend this over my answer nowadays. Don't forget the! My date based timestamp was changing on each refresh and driving me mad - because DateTime was helpfully adding the current time without asking or being told.
I want to add that I recommend against ambiguous date parsing, and that the date format should be given explicitly when parsing date strings. How will be parsed? Probably 09 August What about ? Some versions of PHP parse this as 20 October edited May 23, at Community Bot 1 1 1 silver badge. daremon daremon 4, 2 2 gold badges 27 27 silver badges 27 27 bronze badges.
Valid concern. I guess strtotime relies in your locale. Note: on most non-english speaking countries, the format is dd-mm-yyyy , not mm-dd-yyyy. CamiloMartin Most non-english spoken countries use the first format you stated but the DB usually store the date in YYYY-mm-dd The conversion happens only to display to the users — DJG DannyG just looked at the docs and it seems you're right if by DB you mean MySQL.

This is far better than strtotime For some reason strtotime doesn't work on certain dates, and is therefore very unreliable. answered Apr 6, at klit67 klit67 6 6 silver badges 4 4 bronze badges. To future readers - strtotime was an accident and it's use should not be encouraged.
It's ambiguous, because it tries to guess at the date format. Even if you use it correctly, it makes your code harder to understand and reason about and you run the risk of a change being made to your code base which will introduce errors, because no matter what you give to strtotime , it will make it's best to guess.
