php - 简化数组并保存为 CSV

Question

我有一个非常复杂的数组：

我只想返回 Array ( [display_number] => 00001-Balter and Son [display_number] => 00002-Seamless Solutions )

然后将其保存为 CSV 00001,Balter and Son, 00002,Seamless Solutions

任何帮助都是极好的。我知道必须有一个简单的方法来做到这一点。

有人问PHP。有点难放在这里，但我会尝试。它是 CLIO 法律软件 API 的一部分。

//Get Matters
$matterarry = matter_numbers ($token);

//get array to just matter numbers
$matternumbers = array(); // initialize the array to be used for the export
foreach($matterarry->matters as $key => $matter) { // loop through all the top level element
    // isolate the display number '00001' from '00001-Balter and Son'
    $displayNumber = explode('-', $matter->display_number);
    $displayNumber = $displayNumber[0];

    // push the element the export array using the display_number as the key
        $matternumbers[$key] = array(
            $displayNumber,  // '00001'
            $matter->client->name   // 'Balter and Son'
        );
    }
Print_r ($matternumbers);

//export to CSV
    $f = fopen('/tmp/matternumbers.csv', 'a');  // open the destination file handler
    fputcsv($f, array('display_number', 'name')); // start by adding the column headers
    // this can also be done by using named keys in your array, 
    // or having the first element be the value of the headers
    // I'm appending manually here for the sake of simplicity
    foreach($matternumbers as $key => $element) {
        fputcsv($f, $element); // append each element to the file
    }
    fclose($f); // don't forget to close the file ;)
function matter_numbers ( $token ) {
//$header = array('Authorization: bearer '.$token);
//print_r ($header);
$header = 'Authorization: bearer '.$token;
echo $header."\r\n";
$ch = curl_init();
//curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_URL, 'https://app.goclio.com/api/v2/matters');
curl_setopt($ch, CURLOPT_HTTPHEADER, array($header));
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$resp = curl_exec($ch);

if( !$resp ) {
    die('Error: "' . curl_error( $ch ) . '" - Code: ' . curl_errno( $ch ) );
}

else if ( 200 != curl_getinfo( $ch, CURLINFO_HTTP_CODE ) ) {
    echo "Bad Response Code!";
    echo "\n";
    echo "Response HTTP Status Code : " . curl_getinfo( $ch, CURLINFO_HTTP_CODE );
    echo "\n";
    echo "Response HTTP Body : " . $resp;
}
//print "curl response is:" . $resp;
$resp = json_decode($resp);

//print_r ($resp);
curl_close($ch);

    return $resp;
}

我将尝试解决您问题的两个部分（1）简化数组以隔离特定元素和（2）将其导出到.csv文件

简化数组

为此，您需要遍历matters原始对象的所有元素，并将您希望导出的任何值推送到具有适当格式的新数组中

$exportArray = array(); // initialize the array to be used for the export
foreach($initialObject->matters as $key => $matter) { // loop through all the top level element
    // isolate the display number '00001' from '00001-Balter and Son'
    $displayNumber = explode('-', $matter->display_number);
    $displayNumber = $displayNumber[0];

    // push the element the export array using the display_number as the key
    $exportArray[$key] = array(
        $displayNumber,  // '00001'
        $matter->client->name   // 'Balter and Son'
    );
}

然后你会得到一个看起来有点像这样的数组：

Array [
    0 => Array [
        0 => '00001'
        1 => 'Balter and Son'
    ]
    1 => Array [
        0 => '00002'
        1 => 'Seamless solutions'
    ]
]

array_map()或者，您可以使用并获得类似的结果，而不是遍历数组。如果你不熟悉，你可以在这里array_map()找到官方文档

$exportArray = array_map(function($matter) {
    // isolate the display number '00001' from '00001-Balter and Son'
    $displayNumber = explode('-', $matter->display_number);
    $displayNumber = $displayNumber[0];

    return array(
        $displayNumber,
        $matter->client->name
    );
}, $initialObject->matters)

导出为 CSV

这部分实际上很简单，因为 PHP 有一个专门用于此的功能（官方文档）

$f = fopen('/tmp/myFile.csv', 'a')  // open the destination file handler

fputcsv($f, array('display_number', 'name')) // start by adding the column headers
// this can also be done by using named keys in your array, 
// or having the first element be the value of the headers
// I'm appending manually here for the sake of simplicity
foreach($exportArray as $key => $element) {
    fputcsv($f, $element); // append each element to the file
}
fclose($f) // don't forget to close the file ;)

将两者混合在一起

循环遍历要导出两次的元素很乏味，并且会影响可读性和可维护性。这就是为什么您应该在一个循环中将这些示例混合在一起的原因。

$file = fopen('/tmp/myFile.csv', 'a'); // open the destination file handler
fputcsv($file, array('display_number', 'name')); // add the column headers

foreach($initialObject->matters as $key => $matter) { // loop through all the top level element
    // isolate the display number '00001' from '00001-Balter and Son'
    $displayNumber = explode('-', $matter->display_number);
    $displayNumber = $displayNumber[0];

    // Add the information you need directly in the file
    fputcsv($file, array($displayNumber, $matter->client->name));
}
fclose($file);

为了简单起见，我假设您的目标文件是空的。如果您在开始使用之前不知道如何确保文件为空，我建议您看看这个总结得很好的问题。
