如何在PHP中过滤key的值？

<?php
$array = array(
    'key1' => 'value1',
    'key2' => 'value2',
    'key3' => 'value3',
);

// 过滤掉以"key"开头的键
$filteredArray = array_filter($array, function($key) {
    return strpos($key, 'key') !== 0;
}, ARRAY_FILTER_USE_KEY);

print_r($filteredArray);
?>

Array
(
    [key3] => value3
)

<?php
$array = array(
    'key1' => 'value1',
    'key2' => 'value2',
    'key3' => 'value3',
);

$filteredArray = array();
foreach ($array as $key => $value) {
    if (strpos($key, 'key') !== 0) {
        $filteredArray[$key] = $value;
    }
}

print_r($filteredArray);
?>
