Question

I need to generate a unique ID in php based on current date and time to keep a log of when i am running code. i.e. every time i run the code it should be able to generate a unique id based on current date and time.

Hope I am clear with my ques. How to do that?

Answer 1

Using time() to create sortable unique id's

Concatenating strings will also further randomize your desired result and still keep it sortable. manual here

$uniqueId= time().'-'.mt_rand();

Answer 2

You can use a combination of uniqid() and time() like so:

$s = uniqid(time(), true);

Example output:

1346136883503c6b3330caf5.19553126

Answer 3

Is this what you're looking for? uniqid()

From the doc:

Gets a prefixed unique identifier based on the current time in microseconds.
