如何檢索php stdClass對象的值

Question

這可能很簡單，但是我不知所措。

我正在使用API​​。 我聲明$ checkLead並獲得一個stdClassObject，它將在下面顯示。 我正在嘗試檢索數組的值。 在這種情況下，有一個記錄，但是將來可能會包含更多。

這是我print_r時打印的內容。

stdClass Object ( 
    [result] => stdClass Object ( 
        [count] => 1 
        [leadRecordList] => stdClass Object ( 
            [leadRecord] => stdClass Object ( 
                [Id] => 26 
                [Email] => test3@test.com 
                [ForeignSysPersonId] => 
                [ForeignSysType] => 
                [leadAttributeList] => stdClass Object ( 
                    [attribute] => Array ( 
                        [0] => stdClass Object ( 
                            [attrName] => FirstName 
                            [attrType] => string 
                            [attrValue] => JJ 
                        )
                        [1] => stdClass Object ( 
                            [attrName] => LastName 
                            [attrType] => string 
                            [attrValue] => JJ 
                        ) 
                        [2] => stdClass Object ( 
                            [attrName] => Website 
                            [attrType] => url 
                            [attrValue] => test.com 
                        )
                    )
                )
            )
        )
    )
)

這是一個多結果返回的示例。

stdClass Object (
[result] => stdClass Object (
    [count] => 2
    [leadRecordList] => stdClass Object (
        [leadRecord] => Array (
            [0] => stdClass Object (
                [Id] => 33
                [Email] => test3@test.com
                [ForeignSysPersonId] =>
                [ForeignSysType] =>
                [leadAttributeList] => stdClass Object (
                    [attribute] => Array (
                        [0] => stdClass Object (
                            [attrName] => FirstName
                            [attrType] => string
                            [attrValue] => jj )
                        [1] => stdClass Object (
                            [attrName] => LastName
                            [attrType] => string
                            [attrValue] => amonit )
                        [2] => stdClass Object (
                            [attrName] => Website
                            [attrType] => url
                            [attrValue] => test.com )
                        )
                    )
                )
            [1] => stdClass Object (
                [Id] => 26
                [Email] => test3@test.com
                [ForeignSysPersonId] =>
                [ForeignSysType] =>
                [leadAttributeList] => stdClass Object (
                    [attribute] => Array (
                        [0] => stdClass Object (
                            [attrName] => FirstName
                            [attrType] => string
                            [attrValue] => bob )
                        [1] => stdClass Object (
                            [attrName] => LastName
                            [attrType] => string
                            [attrValue] => smith )
                        [2] => stdClass Object (
                            [attrName] => Phone
                            [attrType] => phone
                            [attrValue] => 123-123-1234 )
                        [3] => stdClass Object (
                            [attrName] => Website
                            [attrType] => url
                            [attrValue] => test.com )
                        )
                    )
                )
            )
        )
    )
)

因此，我想知道是否有人可以幫助我檢索FirstName的值。 我還希望能夠通過說出“ FirstName等於"JJ"的LastName的值是什么”來檢索該值。

Answer 1

您將需要使用foreach來循環查找正確的值

$lastname = '';
foreach($checkLead->result->leadRecordList->leadRecord as $record) {
    $attributes = $record->leadAttributeList->attribute;
    $found = false;
    $temp_lastname = '';
    foreach($attributes as $attr) {
        if($attr->attrName == 'LastName') {
            $temp_lastname = $attr->attrValue;
        }
        if($attr->attrName == 'FirstName' && $attr->attrValue == 'JJ') {
            $found = true;
        }
    }
    if($found) {
        $lastname = $temp_lastname;
        break;
    }
}

Answer 2

為了獲得名聲，您有機會從Marketo獲得多條線索，或者最好是一條線索。 這是獲取該信息的代碼。 希望這可以幫助。

if (is_object($checkLead)) {
    $leadRecord = $checkLead->result->leadRecordList->leadRecord;
    if (is_array($leadRecord)) {
        //multiple leads returned
        //run another foreach within a forloop to get the same values
        for($x=0; $x<sizeof($leadRecord); $x++) {
            $LeadAttribute = $leadRecord[$x]->leadAttributeList->attribute;
            foreach($LeadAttribute as $attribute) {
                if($attribute->attrName == 'FirstName') {
                    echo "\nFirst Name: ".$attribute->attrValue;
                }
            }
        }
    } else {
        //single lead returned
        $LeadAttribute = $leadRecord->leadAttributeList->attribute;
        foreach($LeadAttribute as $attribute) {
            if($attribute->attrName == 'FirstName') {
                echo "\nFirst Name: ".$attribute->attrValue;
            }
        }
    }

}

Answer 3

我相信您可以使用下面的代碼，它將按您期望的方式工作：

$lastname = '';

$leadRecord = $checkLead->result->leadRecordList->leadRecord;
if (  $checkLead->result->count > 1 ) {
    foreach ( $leadRecord as $leadRecordItem ) {
        foreach ( $leadRecordItem->leadAttributeList as $attributes ) {
            $found = false;
            $temp_lastname = '';
            foreach( $attributes as $attr ) {
                if($attr->attrName == 'LastName') {
                    $temp_lastname = $attr->attrValue;
                }
                if($attr->attrName == 'FirstName' && $attr->attrValue == 'JJ') {
                    $found = true;
                }
            }
            if($found) {
                $lastname = $temp_lastname;
                break;
            }
        }
    }
}
else {
    foreach ( $leadRecord->leadAttributeList as $attributes ) {
        $found = false;
        $temp_lastname = '';
        foreach( $attributes as $attr ) {
            if($attr->attrName == 'LastName') {
                $temp_lastname = $attr->attrValue;
            }
            if($attr->attrName == 'FirstName' && $attr->attrValue == 'JJ') {
                $found = true;
            }
        }
        if($found) {
            $lastname = $temp_lastname;
            break;
        }
    }
}

echo $lastname;

我從頭開始構建了兩個對象，並嘗試了此代碼，最后，它回顯了“ JJ”-我想這就是您想要的，至少是要緊抓它並修改您的特定需求。

萬一您想按我的方式嘗試，以下是構建單次和多次結果返回的方法：

function to_object( $arr ) {
    return is_array( $arr ) ? (object) array_map(__FUNCTION__, $arr) : $arr;
}

$checkLeadArr2 = array(
    'result' => array(
        'count' => 2,
        'leadRecordList' => array(
            'leadRecord' => array(
                array(
                    'Id' => 33,
                    'Email' => 'test3@test.com',
                    'ForeignSysPersonId' => null,
                    'ForeignSysType' => null,
                    'leadAttributeList' => array(
                        'attribute' => array( 
                            array(
                                'attrName' => 'FirstName',
                                'attrType' => 'string',
                                'attrValue' => 'JJ',
                            ),
                            array(
                                'attrName' => 'LastName',
                                'attrType' => 'string',
                                'attrValue' => 'amonit',
                            ),
                            array(
                                'attrName' => 'Website',
                                'attrType' => 'url',
                                'attrValue' => 'test.com',
                            ),
                        )
                    )
                ),
                array(
                    'Id' => 26,
                    'Email' => 'test3@test.com',
                    'ForeignSysPersonId' => null,
                    'ForeignSysType' => null,
                    'leadAttributeList' => array(
                        'attribute' => array( 
                            array(
                                'attrName' => 'FirstName',
                                'attrType' => 'string',
                                'attrValue' => 'JJ',
                            ),
                            array(
                                'attrName' => 'LastName',
                                'attrType' => 'string',
                                'attrValue' => 'JJ',
                            ),
                            array(
                                'attrName' => 'Website',
                                'attrType' => 'url',
                                'attrValue' => 'test.com',
                            ),
                        )
                    )
                ),
            )
        )
    )
);

$checkLeadArr1 = array(
    'result' => array(
        'count' => 1,
        'leadRecordList' => array(
            'leadRecord' => array(
                'Id' => 26,
                'Email' => 'test3@test.com',
                'ForeignSysPersonId' => null,
                'ForeignSysType' => null,
                'leadAttributeList' => array(
                    'attribute' => array( 
                        array(
                            'attrName' => 'FirstName',
                            'attrType' => 'string',
                            'attrValue' => 'JJ',
                        ),
                        array(
                            'attrName' => 'LastName',
                            'attrType' => 'string',
                            'attrValue' => 'JJ',
                        ),
                        array(
                            'attrName' => 'Website',
                            'attrType' => 'url',
                            'attrValue' => 'test.com',
                        ),
                    )
                )
            )
        )
    )
);


$checkLead = to_object( $checkLeadArr1 );

您只需要將最后一個代碼放在我之前給您的foreach循環之上，就可以嘗試通過從$checkLead = to_object( $checkLeadArr1 );切換來返回多結果$checkLead = to_object( $checkLeadArr1 ); 和$checkLead = to_object( $checkLeadArr2 );

讓我知道這是否對您有幫助。

Answer 4

簡單地轉換為Array應該可以立即訪問stdClassObject：

$myArray = (array)$myUnusableObject;

echo 'What have we here? '.var_export($myArray, true);
