Does PHP have an equivalent to Python's list comprehension syntax?

Maybe something like this?

$out=array_map(function($x) {return $x*$x;}, range(0, 9))

This will work in PHP 5.3+, in an older version you'd have to define the callback for array_map separately

function sq($x) {return $x*$x;}$out=array_map('sq', range(0, 9));

PHP 5.5 may support list comprehensions - see the mailing list announcement:
