Php 如何检查键相同的多个数组中是否存在值

我得到了一个如下所示的数组：

[0] => Array (
    [status] => success
    [field] => voornaam
    )
[1] => Array (
    [status] => success
    [field] => achternaam
    )
[2] => Array (
    [status] => success
    [field] => telefoon
    )
[3] => Array (
    [status] => error
    [field] => email
    [message] => Vul een email in
    )
[4] => Array (
    [status] => success
    [field] => huisnummer
    )
[5] => Array (
    [status] => success
    [field] => postcode
    )
[6] => Array (
    [status] => success
    [field] => straat
    )
[7] => Array (
    [status] => success
    [field] => woonplaats
    )

我想检查这些数组中是否存在

错误

。我该怎么做

以下是阵列的构建方式：

if (empty($accountform['voornaam'])) {
    $return[] = array('status' => 'error', 'field' => 'voornaam', 'message' => 'Vul een voornaam in');
} else {
    $return[] = array('status' => 'success', 'field' => 'voornaam');
}

if (empty($accountform['achternaam'])) {
    $return[] = array('status' => 'error', 'field' => 'achternaam', 'message' => 'Vul een achternaam in');
} else {
    $return[] = array('status' => 'success', 'field' => 'achternaam');
}

if (empty($accountform['telefoon'])) {
    $return[] = array('status' => 'error', 'field' => 'telefoon', 'message' => 'Vul een telefoonnummer in');
} else {
    $return[] = array('status' => 'success', 'field' => 'telefoon');
}

if (empty($accountform['email'])) {
    $return[] = array('status' => 'error', 'field' => 'email', 'message' => 'Vul een email in');
}else if(!filter_var($accountform['email'], FILTER_VALIDATE_EMAIL)){
    $return[] = array('status' => 'error', 'field' => 'email', 'message' => 'Vul een geldig emailadres in');
} else {
    $return[] = array('status' => 'success', 'field' => 'email');
}

if (empty($accountform['huisnummer'])) {
    $return[] = array('status' => 'error', 'field' => 'huisnummer', 'message' => 'Vul een huisnummer in');
} else {
    $return[] = array('status' => 'success', 'field' => 'huisnummer');
}

if (empty($accountform['postcode'])) {
    $return[] = array('status' => 'error', 'field' => 'postcode', 'message' => 'Vul een postcode in');
} else {
    $return[] = array('status' => 'success', 'field' => 'postcode');
}

if (empty($accountform['straat'])) {
    $return[] = array('status' => 'error', 'field' => 'straat', 'message' => 'Vul een straat in');
} else {
    $return[] = array('status' => 'success', 'field' => 'straat');
}

if (empty($accountform['woonplaats'])) {
    $return[] = array('status' => 'error', 'field' => 'woonplaats', 'message' => 'Vul een woonplaats in');
} else {
    $return[] = array('status' => 'success', 'field' => 'woonplaats');
}

我试过：

if (in_array('error', $return)) {
    echo "There is an error";
}

但if语句从未触发

$status_rows = array_column($your_array,'status');
var_dump(in_array('error',$status_rows));

您可以使用来获取所有状态，并使用来检查它是否存在。

您可以使用数组搜索并检查它是否存在

$key = array_search('error', array_column($return, 'status'));
if($key){
   echo 'found';
}else{
   echo 'not found';
}

代码不起作用的原因是$result在另一个数组（如[0]和[1]等）中有值

Array
(
    [0] => Array
        (
            [status] => error
            [field] => telefoon
            [message] => Vul een telefoonnummer in
        )

    [1] => Array
        (
            [status] => success
            [field] => achternaam
        )

)

因此，如果希望代码正常工作，则需要$result[0]、$result[1]等等。。因此，您的代码应该在foreach循环中

foreach ($return as $key => $value) {
    if (in_array('error', $value)) {
        echo "There is an error";
    }
}

$value现在有$result数据，没有[0][1]，现在可以与数组中的fn进行比较。

如果使用数组搜索，请确保进行严格比较，因为在第0个索引中也可以找到特定的键。
