使用递归替换数组中的内容

<?php
    $arr = array("<小刚>","<小晓>","<小飞>","<小李>","<小红>");
    function arrContentReplact($array)
    {
        if(is_array($array))
        {
            foreach($array as $k => $v)
            {
                $array[$k] = arrContentReplact($array[$k]);
            }
        }else
        {
            $array = str_replace(array('<', '>'), array('{', '}'), $array);
        }
        return $array;
    }
    
    $arr3 = arrContentReplact($arr);
    
    echo "<pre>";
    print_r($arr3);
    echo "</pre>";
?>
