Benchmark: strtotime() vs DateTime vs getTimestamp in PHP
Recently I wrote about how one can implement date comparison in PHP. In the article I presented two approaches. Firstly, using the strtotime() method and another with the DateTime class.

How did I test the performance?
Since the question aims on strtotime() vs. DateTime, the DateTime class is contrary to the strtotime() function. So because DateTime class offers more functionality, I had first to create the DateTime object and then get the timestamp of it, because the strtotime function gives a timestamp as return value and I wanted to compare the time needed to generate the identical output.
