Sorting array by values PHP

Question

I am sorting through an array using the usort function. The loop is working correctly as is the sorting (to some degree) however I seem to have missed something with regards to decimal places etc. My function is below

usort($this->view->blogs, 'comparison');

And here is the function. The function call works correctly and I can see I am returned sorted data

function comparison($a, $b)
{
    return strcmp($a->cost_per_blog, $b->cost_per_blog);
}

The issue is with the actual sorting logic for instance I am returned a list like below

the pattern continues... It appears that I am not taking into account the sorting of 3 digit numbers. I cant seem to think of what I am missing. Any help would be greatly appreciated.

Don't compare strings then, compare numbers:

return $a->cost_per_blog - $b->cost_per_blog;

You compare them as strings not as doubles.
