在下面的数组中,提取我想要的数据['rowid']
的最佳方法是什么。我尝试了类似的东西,但似乎无法得到它。
阵列:
array(4) {
["b5cfec3e70d0d57ea848d5d8b9f14d61"]=> array(7) {
["rowid"]=> string(32) "b5cfec3e70d0d57ea848d5d8b9f14d61"
["id"]=> string(3) "232"
["qty"]=> string(1) "1"
["price"]=> string(2) "15"
["name"]=> string(13) " DVD"
["options"]=> array(4) {
["description"]=> string(43) " retail DVD for personal use only."
["image"]=> string(36) "d31e3bc3e820b7faef50a400f721125a.jpg"
["additional_info"]=> NULL
["attributes"]=> string(29) "a:1:{s:6:"Format";s:3:"PAL";}"
}
["subtotal"]=> int(15)
}
["eda80a3d5b344bc40f3bc04f65b7a357"]=> array(7) {
["rowid"]=> string(32) "eda80a3d5b344bc40f3bc04f65b7a357"
["id"]=> string(3) "267"
["qty"]=> string(1) "1"
["price"]=> string(4) "9.99"
["name"]=> string(3) "DVD"
["options"]=> array(4) {
["description"]=> string(0) ""
["image"]=> string(0) ""
["additional_info"]=> NULL
["attributes"]=> NULL
}
["subtotal"]=> float(9.99)
}
["total_items"]=> int(2)
["cart_total"]=> float(24.99)
}

由于您的数组包含您不需要迭代的值,因此创建一个包含要跳过的键的数组,然后您可以成功地每次迭代选择行ID:
<?php
// array keys to skip
$skip = array( 'total_items', 'cart_total' );
foreach($yourarray as $key => $row) {
if(in_array($key, $skip))
continue; // skip values we don't need in this array
echo $row['rowid'] . "\n";
}
// output:
// b5cfec3e70d0d57ea848d5d8b9f14d61
// eda80a3d5b344bc40f3bc04f65b7a357
?>

使用array_column选择列:
$selected_rowids = array_column($yourarrayname, 'row_id');
如果你想拥有一个id =&gt; row_id数组:
$selected_rowids = array_column($yourarrayname, 'row_id', 'id');
