Question

嗨我希望在与另一个数组比较时过滤掉一些键和值。 “内容”对应该显示在最后......任何帮助都非常感谢THX很多！

<?php
$test = array(
            ['slideid'] => 597,
            ['token'] =>'4e23fdd176372984870a9c65db7133b5',
            ['content'] =>'<p>sdg</p>',
        )
$test2 = array(
            ['slideid'] => "",
            ['token'] =>""
            )

foreach ($test not in $test2){
    print $test2
} //not working of course   

?>

Answer 1

这有效：

$test = array(
    'slideid' => 597,
    'token' =>'4e23fdd176372984870a9c65db7133b5',
    'content' =>'<p>sdg</p>'
);
$test2 = array(
    'slideid' => "",
    'token' =>""
);

foreach ($test as $key => $value){
    if (!array_key_exists($key, $test2)) {
        echo $value;
    }
}

Answer 2

$arr包含test但不是test2

中的元素

$arr = array_diff(array_keys($test), array_keys($test2));
print_r($arr);

从数组中获取密钥及其值的最佳方法，仅在其他数组中与其密钥进行比较
