array_count_values
計算一維數組中所有值出現的個數
<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>
輸出：
<code><span>Array</span>
(
[<span>1</span>] => <span>2</span>
[hello] => <span>2</span>
