array_count_values

Count the number of occurrences of all values in a one-dimensional array

<code><span>$array</span> = <span>array</span>(<span>1</span>, <span>"hello"</span>, <span>1</span>, <span>"world"</span>, <span>"hello"</span>);
print_r(array_count_values(<span>$array</span>));</code>

Copy after login

Output:

<code><span>Array</span>
(
    [<span>1</span>] => <span>2</span>
    [hello] => <span>2</span>
    [world] => <span>1</span>
