Count number of iterations in a foreach loop

Question

How to calculate how many items in a foreach?

I want to count total rows.

foreach ($Contents as $item) {
    $item[number];// if there are 15 $item[n         


        

Answer 1

$Contents = array(
    array('number'=>1), 
    array('number'=>2), 
    array('number'=>4), 
    array('number'=>4), 
    array('number'=>4), 
    array('number'=>5)
);

$counts = array();

foreach ($Contents as $item) {
    if (!isset($counts[$item['number']])) {
        $counts[$item['number']] = 0;
    }
    $counts[$item['number']]++;
}

echo $counts[4]; // output 3
