PHP - Count the values of an array not the keys?

Question

In an array like this:

$array = array(
    'value1'=>'',
    'value2'=>'',
    'value3'=>'',
);

We can:

echo count($array);
// Outputs 3

But if we have an array like:

$array = array(
    'value1'=>'',
    'value2'=>'some value',
    'value3'=>'',
);

What is the best way to do the following?

echo someFunction($array);
// Outputs 1

What result do you expect for [0, 'foo', '', null, false]? — georg

Use array_filter in order to remove the empty values:

$array = array(
    'value1'=>'',
    'value2'=>'some value',
    'value3'=>'',
);
echo count(array_filter($array)); // prints 1

loop over the array and test each element for truthy

Same as array_filter, but faster (and does not allocate another array, so less memory used)
