Question

我正在尝试从表woocommerce中读取wp_options中已弃用的购物车详情。字符串格式低于

a:19:{s:4:"cart";s:308:"a:1:{s:32:"d3d9446802a44259755d38e6d163e820";a:9:{s:10:"product_id";i:10;s:12:"variation_id";s:0:"";s:9:"variation";a:0:{}s:8:"quantity";i:1;s:10:"line_total";d:189;s:8:"line_tax";i:0;s:13:"line_subtotal";i:189;s:17:"line_subtotal_tax";i:0;s:13:"line_tax_data";a:2:{s:5:"total";a:0:{}s:8:"subtotal";a:0:{}}}}";s:15:"applied_coupons";s:6:"a:0:{}";s:23:"coupon_discount_amounts";s:6:"a:0:{}";s:27:"coupon_discount_tax_amounts";s:6:"a:0:{}";s:21:"removed_cart_contents";s:6:"a:0:{}";s:19:"cart_contents_total";d:189;s:20:"cart_contents_weight";i:2;s:19:"cart_contents_count";i:1;s:5:"total";i:0;s:8:"subtotal";i:189;s:15:"subtotal_ex_tax";i:189;s:9:"tax_total";i:0;s:5:"taxes";s:6:"a:0:{}";s:14:"shipping_taxes";s:6:"a:0:{}";s:13:"discount_cart";i:0;s:14:"shipping_total";i:0;s:18:"shipping_tax_total";i:0;s:9:"fee_total";i:0;s:4:"fees";s:6:"a:0:{}";}

如何拆分此值以阅读购物车和产品详情。

Answer 1

您的字符串已序列化。你必须反序列化它。您可以使用在线工具。

http://www.unserialize.com/

或者，您可以运行PHP代码;

<?php

   $serialized = 'a:19:{s:4:"cart";s:308:"a:1:{s:32:"d3d9446802a44259755d38e6d163e820";a:9:{s:10:"product_id";i:10;s:12:"variation_id";s:0:"";s:9:"variation";a:0:{}s:8:"quantity";i:1;s:10:"line_total";d:189;s:8:"line_tax";i:0;s:13:"line_subtotal";i:189;s:17:"line_subtotal_tax";i:0;s:13:"line_tax_data";a:2:{s:5:"total";a:0:{}s:8:"subtotal";a:0:{}}}}";s:15:"applied_coupons";s:6:"a:0:{}";s:23:"coupon_discount_amounts";s:6:"a:0:{}";s:27:"coupon_discount_tax_amounts";s:6:"a:0:{}";s:21:"removed_cart_contents";s:6:"a:0:{}";s:19:"cart_contents_total";d:189;s:20:"cart_contents_weight";i:2;s:19:"cart_contents_count";i:1;s:5:"total";i:0;s:8:"subtotal";i:189;s:15:"subtotal_ex_tax";i:189;s:9:"tax_total";i:0;s:5:"taxes";s:6:"a:0:{}";s:14:"shipping_taxes";s:6:"a:0:{}";s:13:"discount_cart";i:0;s:14:"shipping_total";i:0;s:18:"shipping_tax_total";i:0;s:9:"fee_total";i:0;s:4:"fees";s:6:"a:0:{}";}';

   $unserialized = unserialize( $serialized );

   var_dump( $unserialized );

?>

Answer 2

您正在显示的字符串已序列化。 Serializing是一种将PHP值（在本例中为数组）及其类型和结构存储为字符串的方法。

您可以使用PHP的unserialize函数将字符串转换回PHP值：

$value = unserialize($value);

这将返回一个包含cart键的数组，由于某种原因，该数组也被序列化，因此您必须再次使用unserialize：

$cart = unserialize($value['cart']);

现在您将能够访问购物车数据。

echo $cart['d3d9446802a44259755d38e6d163e820']['product_id']; // 10
