Random float number between 0 and 1.0 php [duplicate]

Answer 1

$v = mt_rand() / mt_getrandmax();

will do that.

In case you want only one decimal place (as in the examples from the question) just round() the value you get...

$v = round( $v, 1 );

...or calculate a number between 0 and 10 and divide by 10:

$v = mt_rand( 0, 10 ) / 10;
