I've got 2 integers. I need to know which one has minimum value and get this value. Is there any pretty way (one function?) to do it? Now i'm doing it this way:

$foo = 5;
$bar = 7;
$min = min($foo, $bar);
if($min == $foo) {
...
}
else {
...
}

回答1:

Use min() if you need to work with the lower value.

$min = min($foo, $bar);
print "min: $min";

And use a regular if if you simply want to do the comparison

if ($foo <= $bar)
{
    // $foo is smaller/equal
}
else
{
    // $bar is smaller
}
