PHP JSON解码到数组以获取特定键值（所有字段同名）答案

【问题标题】：PHP JSON Decoding To Array To Grab Specific Key Values (All fields same name)PHP JSON解码到数组以获取特定键值（所有字段同名）
【发布时间】：2019-08-26 11:20:17
【问题描述】：

我正在从 API URL 中提取 JSON 数据。问题：在 FL 下有重复的 KEYS：“val”和“content”。我只需要提取特定的 KEYS。

如果我的格式不符合 SO 标准，请见谅。*

我的问题贴在json和代码下面。

来自 URL 的 JSON

    }
}

PHP 代码

$url = 'URL';
$data = file_get_contents($url);
$parsed = json_decode($data, true);

$eachEntry = $parsed['response']['result']['Leads']['row'];

foreach ($eachEntry as $entry) {

    $FL = $entry['no'];

    //printf('%s'.PHP_EOL, $FL);
    printf("\n");

    $entries = $entry['FL'];

    foreach ($entries as $value) {

        $val = $value['val'];

        $content = $value['content'];

        $out = $val." ".$content;

        printf('%s'.PHP_EOL, $out);
        printf("\n");
    } 

}

结果

问题

如何仅提取示例中下面列出的字段？并且不要拉所有领域。

示例

"val": "First Name",
"content": "Bobby"

,

"val": "Last Name",
"content": "Something"

,

"val": "Street",
"content": "123 Fake Rd"

,

"val": "City",
"content": "Fakecity"

,

"val": "State",
"content": "FK"

,

"val": "Zip Code",
"content": "11111"

预期输出

First Name Bobby

Last Name Bobby

Street 123 Fake Rd

City Fakecity

State FK

Zip Code 11111

【解决方案1】：

只需编写代码来执行您描述的操作。如果它们不在您想要的字段列表中，请不要打印它们。

$valuesIWant = ["First Name", "Last Name", "Street", "City", "State", "Zip Code"];

foreach ($eachEntry as $entry) {

    $FL = $entry['no'];

    //printf('%s'.PHP_EOL, $FL);
    printf("\n");

    $entries = $entry['FL'];

    foreach ($entries as $value) {

        $val = $value['val'];

        $content = $value['content'];

        if (in_array($val, $valuesIWant)) {
            $out = $val." ".$content;

            printf('%s'.PHP_EOL, $out);
            printf("\n");
        }

    } 
}

真的就是这么简单:) - 标记为答案。非常感谢！

【解决方案2】：

您只需要维护一个数组，您可以在其中提供您想要获取的所有选项并在循环中检查这些选项，如下例所示。

$url = 'URL';
$data = file_get_contents($url);
$parsed = json_decode($data, true);

$eachEntry = $parsed['response']['result']['Leads']['row'];

$required = ['First Name','Last Name','Street','City','State','Zip Code'];

foreach ($eachEntry as $entry) {

    $FL = $entry['no'];

    //printf('%s'.PHP_EOL, $FL);
    printf("\n");

    $entries = $entry['FL'];

    foreach ($entries as $value) {

        if(!in_array($value['val'],$required))
            continue;

        $val = $value['val'];

        $content = $value['content'];

        $out = $val." ".$content;

        printf('%s'.PHP_EOL, $out);
        printf("\n");
   } 

}
