将数组值中的数组存储到 PHP 变量中

Question

>我正在使用XML解析器将xml源数据存储到mysql表中，如果我得到一个XML文件结果作为数组，结果如下所示。如何将每个值存储到变量中。

不仅仅是这种类型的数组，如果我们使用不同的XML文件或URL，它的结果可能不是多维数组。

如何将数组值存储在 php 变量中

   <?php
function objectsIntoArray($arrObjData, $arrSkipIndices = array())
{
    $arrData = array();
    // if input is object, convert into array
    if (is_object($arrObjData)) {
        $arrObjData = get_object_vars($arrObjData);
    }
    if (is_array($arrObjData)) {
        foreach ($arrObjData as $index => $value) {
            if (is_object($value) || is_array($value)) {
                $value = objectsIntoArray($value, $arrSkipIndices); // recursive call
            }
            if (in_array($index, $arrSkipIndices)) {
                continue;
            }
            $arrData[$index] = $value;
        }
    }
    return $arrData;
}

$xmlUrl = "testxmel.xml"; // XML feed file/URL
$xmlStr = file_get_contents($xmlUrl);
$xmlObj = simplexml_load_string($xmlStr);
$arrXml = objectsIntoArray($xmlObj);

泰斯特梅尔.xml

<?xml version="1.0" encoding="utf-8"?>
<everyone>
  <guest>
    <name>Joseph Needham</name>
    <age>53</age>
  </guest>
  <guest>
    <name>Lu Gwei-djen</name>
    <age>31</age>
  </guest>
</everyone>

任何人都可以帮助我解决这个XML解析器结果问题。提前致谢

Answer 1

// let's assume $myArray is your array
$guest = count( $myArray ); // no. of guests
foreach( $myArray as $guests ) {
   $name = $guests[ 'name' ];
   $age = $guests[ 'age' ];
   // work with this data here...
}

希望这有帮助。

使用 pdo 的独立示例

<?php
$pdo = new PDO('mysql:host=localhost;dbname=test;charset=utf8', 'localonly', 'localonly');
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
setup($pdo);
$stmt = $pdo->prepare('INSERT INTO soFoo (name, age) VALUES (:name, :age)');
$stmt->bindParam('name', $name);
$stmt->bindParam('age', $age);

$data = data();
// number of elements in $data['guest']
echo count($data['guest']), " new entries<br />n";
// add data to mysql database
// iterate over elements in  $data['guest']
foreach( $data['guest'] as $row ) {
    // assign "values" to the previously bound parameters
    $name = $row['name'];
    $age = $row['age'];
    // execute preapred statement
    $stmt->execute();
}
$stmt = null;
// retrieve data: only count
// if you only want count the records do not transfer the data from the mysql server to your php process - use Count(*) instead
$row = $pdo->query('SELECT Count(*) from soFoo')->fetch();
echo $row[0], " entries in database<br />n";
// retrieve data: actual data
$stmt = $pdo->query('SELECT name, age from soFoo', PDO::FETCH_ASSOC);
foreach( $stmt as $row ) {
    echo $row['name'], ' ', $row['age'], "<br />n";
}
// stmt->rowCount() after a SELECT statement doesn't work with all pdo drivers, but for PDO_MySQL it does
echo $stmt->rowCount(), ' records fetched';
// boilerplate: create temporary database structure ...
function setup($pdo) {
    $pdo->exec('
        CREATE TEMPORARY TABLE soFoo (
            id int auto_increment,
            name varchar(32),
            age int,
            primary key(id)
        )
    ');
}
// boilerplate: a function returning example data to work on...
function data() {
    return array (
        'guest' => array (
            array (
                'name' => 'Joseph Needham',
                'age' => 53
            ),
            array (
                'name' => 'Lu Gwei-djen',
                'age' => 31
            )
        )
    );
}

编辑：给定您的XML，您可以执行以下操作

<?php
$pdo = new PDO('mysql:host=localhost;dbname=test;charset=utf8', 'localonly', 'localonly');
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
setup($pdo);
$stmt = $pdo->prepare('INSERT INTO soFoo (name, age) VALUES (:name, :age)');
$stmt->bindParam('name', $name);
$stmt->bindParam('age', $age);
// insert data
$data = data();
echo count($data->guest), " new entries<br />n";
foreach( $data->guest as $guest ) {
    $name = (string)$guest->name;
    $age = (string)$guest->age;
    $stmt->execute();
}
$stmt = null;
// retrieve data: only count
$row = $pdo->query('SELECT Count(*) from soFoo')->fetch();
echo $row[0], " entries in database<br />n";
// retrieve data: actual data
$stmt = $pdo->query('SELECT name, age from soFoo', PDO::FETCH_ASSOC);
foreach( $stmt as $row ) {
    echo $row['name'], ' ', $row['age'], "<br />n";
}
echo $stmt->rowCount(), ' records fetched';

function setup($pdo) {
    $pdo->exec('
        CREATE TEMPORARY TABLE soFoo (
            id int auto_increment,
            name varchar(32),
            age int,
            primary key(id)
        )
    ');
}
function data() {
    // return simplexml_load_file('...');
    return new SimpleXMLElement( <<< eox
<?xml version="1.0" encoding="utf-8"?>
<everyone>
  <guest>
    <name>Joseph Needham</name>
    <age>53</age>
  </guest>
  <guest>
    <name>Lu Gwei-djen</name>
    <age>31</age>
  </guest>
</everyone>
eox
    );
}

输出是相同的。
但请记住，simplxml_load_file（） 将整个 DOM 保存在内存中。如果您的数据源变大，这可能会成为一个问题，您最好切换到 XMLReadery，
