Question

我想迭代以下数组（这是print_r时的输出）：

Array ( 
    [GetRecentCasesResult] => Array ( 
        [CaseHistory] => Array ( 
            [0] => Array ( 
                [caseNumber] => CAS-00305-Q0S7Y5 
                [dateCreated] => 2016-01-17 11:00:09 AM 
                [faultType] => Repair Blocked Sewer - Small Pipes 
                [status] => Open 
            ) 
            [1] => Array ( 
                [caseNumber] => CAS-00308-W4F8F0 
                [dateCreated] => 2016-01-17 01:17:04 PM 
                [faultType] => Repair Pothole in Major Road 
                [status] => Open 
            ) 
            [2] => Array ( 
                [caseNumber] => CAS-00309-T8B2J6 
                [dateCreated] => 2016-01-17 01:44:38 PM 
                [faultType] => Repair Pothole in Major Road 
                [status] => Open 
            ) 
            [3] => Array ( 
                [caseNumber] => CAS-00311-K7H8D9 
                [dateCreated] => 2016-01-17 02:18:29 PM 
                [faultType] => Electricity outage - Business 
                [status] => Open 
            ) 
            [4] => Array ( 
                [caseNumber] => CAS-00303-C8M0K8 
                [dateCreated] => 2016-01-17 10:14:45 AM 
                [faultType] => Electricity outage - Business 
                [status] => Open 
            ) 
            [5] => Array ( 
                [caseNumber] => CAS-00306-R7W8S7 
                [dateCreated] => 2016-01-17 11:14:40 AM 
                [faultType] => Animal Carcass Removal 
                [status] => Open 
            ) 
            [6] => Array ( 
                [caseNumber] => CAS-00307-B5Q6C0 
                [dateCreated] => 2016-01-17 11:17:22 AM 
                [faultType] => Water Leak 
                [status] => Open
            ) 
        ) 
    )
)

我尝试了以下代码：

foreach ($result as $firtsone) {
foreach ($firtsone as $key => $value) {
    echo $key.": ".$value;
}
}

这是我得到的错误：

注意：第30行的C：\ xampp \ htdocs \ emgtsz \ faulth.php中的数组到字符串转换 CaseHistory：数组

请协助。

<强>问题：

这是我得到的结果：注意：第30行的C：\ xampp \ htdocs \ emgtsz \ faulth.php中的数组转换为字符串CaseHistory：Array

那是因为$value并不总是一个字符串，它可能是一个数组。

解决方案：

递归迭代数组并打印（键，值）对，如下所示：

function process_array($array){
    foreach($array as $key => $value){
        if(is_array($value)){
            process_array($value);
        }else{
            echo $key . ": " . $value . "<br />";
        }
    }
}

process_array($result);

我如何将这些显示为表而不是一个接一个？

使用迭代方法，如下所示：

echo "<table border='1'>";
echo "<tr>";
echo "<th>Case Number</th>";
echo "<th>Date Created</th>";
echo "<th>Fault Type</th>";
echo "<th>status</th>";
echo "</tr>";

$arrayLength = count($result['GetRecentCasesResult']['CaseHistory']);
for($i = 0; $i < $arrayLength; ++$i){
    echo "<tr>";
    echo "<td>" . $result['GetRecentCasesResult']['CaseHistory'][$i]['caseNumber'] . "</td>";
    echo "<td>" . $result['GetRecentCasesResult']['CaseHistory'][$i]['dateCreated'] . "</td>";
    echo "<td>" . $result['GetRecentCasesResult']['CaseHistory'][$i]['faultType'] . "</td>";
    echo "<td>" . $result['GetRecentCasesResult']['CaseHistory'][$i]['status'] . "</td>";
    echo "</tr>";
}

echo "</table>";

迭代通过多维关联数组
