我有一個具有以下結構的數組： Array ( [DigitalAssets] => Array ( [0] => Array ( [PartNumber] => 0276S-4 [Link] => https://1ddf4b1b856a39e33863-d785dc0e3b62b5e0ef07f55db00b0659.ssl.cf2.rackcdn.com/Holley/0576s-4.jpg [AssetTypeCode] => P04 [FileName] => 0576s-4.jpg [RecordModifiedDate] => 2020-05-13T18:59:10.28 ) [1] => Array ( [PartNumber] => 0437S-4 [Link] => https://1ddf4b1b856a39e33863-d785dc0e3b62b5e0ef07f55db00b0659.ssl.cf2.rackcdn.com/Holley/0437s-4.jpg [AssetTypeCode] => P04 [FileName] => 0437s-4.jpg [RecordModifiedDate] => 2020-05-13T18:59:11.687 ) [2] => Array ( [PartNumber] => 0574S-4 [Link] => https://1ddf4b1b856a39e33863-d785dc0e3b62b5e0ef07f55db00b0659.ssl.cf2.rackcdn.com/Holley/0574s-4.jpg [AssetTypeCode] => P04 [FileName] => 0574s-4.jpg [RecordModifiedDate] => 2020-05-13T18:59:12.593 )我想計算數組的總索引，以便相應地運行循環。我使用了 Count($array) 和 Count ($array,RECURSIVE) 但它無法返回正確的索引總數。只能引導那個怎么辦？

如果你想計算DigitalAssets直接孩子你可以這樣做 count($array['DigitalAssets'])
這里有一些測試count應該如何工作。
代碼是：
$test = array
(
'DigitalAssets' => array
(
0 => array(
'PartNumber' => '0276S-4',
'Link' => 'https://1ddf4b1b856a39e33863-d785dc0e3b62b5e0ef07f55db00b0659.ssl.cf2.rackcdn.com/Holley/0576s-4.jpg',
'AssetTypeCode' => 'P04',
'FileName' => '0576s-4.jpg',
'RecordModifiedDate' => '2020-05-13T18:59:10.28'
),
1 => array(
'PartNumber' => '0437S-4',
'Link' => 'https://1ddf4b1b856a39e33863-d785dc0e3b62b5e0ef07f55db00b0659.ssl.cf2.rackcdn.com/Holley/0437s-4.jpg',
'AssetTypeCode' => 'P04',
'FileName' => '0437s-4.jpg',
'RecordModifiedDate' => '2020-05-13T18:59:11.687'
),
2 => array
(
'PartNumber' => '0574S-4',
'Link' => 'https://1ddf4b1b856a39e33863-d785dc0e3b62b5e0ef07f55db00b0659.ssl.cf2.rackcdn.com/Holley/0574s-4.jpg',
'AssetTypeCode' => 'P04',
'FileName' => '0574s-4.jpg',
'RecordModifiedDate' => '2020-05-13T18:59:12.593'
)
)
);
echo count($test['DigitalAssets'])." ".count($test['DigitalAssets'], 0)." ".count($test['DigitalAssets'], 1);
exit();
結果在我的情況下： 3 3 18
這意味著在我的例子中，mode默認情況下計數設置為 0，所以我將只計算第一級。如果我將模式設置為 1，我也會計算所有嵌套項目。這應該為您解決問題。
