Set printf() value in a PHP variable

Question

I have a php script that show a time like: 9.08374786377E-5 , but i need plain floating value as a time like : 0.00009083747..... Thats why i just print it with float like that: ``` <?php function microtime_float() { list($usec, $sec) = explode(" ", microtime()); return ((float)$usec + (float)$sec); } $time_start = microtime_float(); $time_end = microtime_float(); $time = $time_end - $time_start; printf('%.16f', $time); ?> ``` Its show the result nicely, but i need to set this printing value in a new variable. how can i do that ? I need to set this printing value in a new variable $var; ``` $var = printf('%.16f', $time); ``` // We all know its not working, but how to set ?

Accepted Answer

You need to use the sprintf command to get your data as a variable... printf outputs the results whereas sprintf returns the results

```
$var = sprintf('%.16f', $time); 
```
