HOW TO USE THE microtime() FUNCTION IN PHP

The microtime() function returns the current Unix Timestamp in microseconds as a string.

In it's simple form:

echo microtime();

This will output:

0.45526900 1231206212

The string outputted is in the form: microseconds seconds. Both these are outputted in seconds format.

The microtime() function could also take an optional argument: get_as_float. If this is set to true, then the output is a float and not a string as follows:

echo microtime(true);

This will output:

1231206212.4553
