Count and display occurrences of unique values in an array

I am working with a one dimensional array in PHP. I would like to detect the presence of duplicate values, then count the number of duplicate values and output the results. For example, given the following array:

$array = [
    'apple',
    'orange',
    'pear',
    'banana',
    'apple',
    'pear',
    'kiwi',
    'kiwi',
    'kiwi'
];

I would like to print:

apple (2)
orange
pear (2)
banana
kiwi (3)

Any advice on how to approach this problem?

Perhaps something like this (untested code but should give you an idea)?

$new = array();

foreach ($array as $value)
{
    if (isset($new[$value]))
        $new[$value]++;
    else
        $new[$value] = 1;
}

Then you'll get a new array with the values as keys and their value is the number of times they existed in the original array.
