PHP有像matlab的linspace这样的函数吗？

I want this to execute the following code in PHP

linspace(1,7,4);

I want to have linear array list as an output.

function linspace($i,$f,$n){
    $step = ($f-$i)/($n-1);
    return range ($i,$f,$step);
}

$test = linspace(0,3.14159,8);

print_r($test);

I have written my own in some minutes. Please test it out.

function range is your friend: http://php.net/manual/en/function.range.php

range(0, 12); //array(0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12)
