如何解析wordpress post_meta表值

Question

我必须解析wordpress post_meta 表,特别是 "_wp_attachment_metadata"字段

例如:

它的值是post id = 99

> a:6:{s:5:"width";s:3:"238";s:6:"height";s:3:"179";s:14:"hwstring_small";s:23:"height='96'
> width='128'";s:4:"file";s:21:"2010/11/matt-lane.jpg";s:5:"sizes";a:1:{s:9:"thumbnail";a:3:{s:4:"file";s:21:"matt-lane-150x150.jpg";s:5:"width";s:3:"150";s:6:"height";s:3:"150";}}s:10:"image_meta";a:10:{s:8:"aperture";s:1:"0";s:6:"credit";s:0:"";s:6:"camera";s:0:"";s:7:"caption";s:0:"";s:17:"created_timestamp";s:1:"0";s:9:"copyright";s:0:"";s:12:"focal_length";s:1:"0";s:3:"iso";s:1:"0";s:13:"shutter_speed";s:1:"0";s:5:"title";s:0:"";}}

我不明白它是如何编译或如何在wordpress之外解析它.我必须从wordpress加载magento平台上发布的所有数据集的最新文章.

请帮我解析这些数据以获得图像src.

提前致谢

Answer 1

尝试:

$a = unserialize("");
print_r($a);

Answer 2

我的理解是:

有两种类型的变量,例如:

1. a:6:
2. s:3:

a= array并且6是array
s= string 的维度,并且3是字符串的长度
