如何修复array_count_value中的空格错误

<?php
function fix_array_count_value($array) {
    $fixed_array = array();
    
    foreach ($array as $element) {
        $trimmed_element = trim($element);
        
        if ($trimmed_element !== $element) {
            // Element contains whitespace error
            $fixed_element = str_replace(' ', '_', $trimmed_element); // Replace whitespace with underscore
            $fixed_array[] = $fixed_element;
        } else {
            $fixed_array[] = $element;
        }
    }
    
    $counted_values = array_count_values($fixed_array);
    
    return $counted_values;
}

// 示例用法
$array = array("apple", "banana", "orange ", "orange", "grape ", "grape");
$result = fix_array_count_value($array);
print_r($result);
?>

Array
(
    [apple] => 1
    [banana] => 1
    [orange] => 2
    [grape] => 2
)
