用PHP解析Wordpress JSON

对于我来说，作为一名PHP初学者，Wordpress在mySql数据库中存储的JSON结构相当复杂。但我想从复杂的JSON结构中获得某些信息。您可以帮助从人类友好的结构中使用PHP获取数据的JSON字符串吗？用PHP解析Wordpress JSON

我想要得到的文件名附近的 “文件” 元素：

a: 5: { 
s: 5: "width";i: 428;s: 6: "height";i: 324;s: 4: "file";s: 15: "Clipboard12.jpg";s: 5: "sizes";a: 9: { 
    s: 9: "thumbnail";a: 4: { 
     s: 4: "file";s: 23: "Clipboard12-150x150.jpg";s: 5: "width";i: 150;s: 6: "height";i: 150;s: 9: "mime-type";s: 10: "image/jpeg"; 
    } 
    s: 6: "medium";a: 4: { 
     s: 4: "file";s: 23: "Clipboard12-300x227.jpg";s: 5: "width";i: 300;s: 6: "height";i: 227;s: 9: "mime-type";s: 10: "image/jpeg"; 
    } 
    s: 14: "post-thumbnail";a: 4: { 
     s: 4: "file";s: 22: "Clipboard12-100x65.jpg";s: 5: "width";i: 100;s: 6: "height";i: 65;s: 9: "mime-type";s: 10: "image/jpeg"; 
    } 
    s: 9: "art-thumb";a: 4: { 
     s: 4: "file";s: 22: "Clipboard12-100x65.jpg";s: 5: "width";i: 100;s: 6: "height";i: 65;s: 9: "mime-type";s: 10: "image/jpeg"; 
    } 
    s: 8: "art-wide";a: 4: { 
     s: 4: "file";s: 23: "Clipboard12-326x159.jpg";s: 5: "width";i: 326;s: 6: "height";i: 159;s: 9: "mime-type";s: 10: "image/jpeg"; 
    } 
    s: 12: "art-big-1col";a: 4: { 
     s: 4: "file";s: 23: "Clipboard12-326x235.jpg";s: 5: "width";i: 326;s: 6: "height";i: 235;s: 9: "mime-type";s: 10: "image/jpeg"; 
    } 
    s: 15: "art-slide-small";a: 4: { 
     s: 4: "file";s: 23: "Clipboard12-326x324.jpg";s: 5: "width";i: 326;s: 6: "height";i: 324;s: 9: "mime-type";s: 10: "image/jpeg"; 
    } 
    s: 7: "art-gal";a: 4: { 
     s: 4: "file";s: 23: "Clipboard12-210x210.jpg";s: 5: "width";i: 210;s: 6: "height";i: 210;s: 9: "mime-type";s: 10: "image/jpeg"; 
    } 
    s: 10: "td_198x143";a: 4: { 
     s: 4: "file";s: 23: "Clipboard12-198x143.jpg";s: 5: "width";i: 198;s: 6: "height";i: 143;s: 9: "mime-type";s: 10: "image/jpeg"; 
    } 
} 
s: 10: "image_meta";a: 11: { 
    s: 8: "aperture";i: 0;s: 6: "credit";s: 0: "";s: 6: "camera";s: 0: "";s: 7: "caption";s: 0: "";s: 17: "created_timestamp";i: 0;s: 9: "copyright";s: 0: "";s: 12: "focal_length";i: 0;s: 3: "iso";i: 0;s: 13: "shutter_speed";i: 0;s: 5: "title";s: 0: "";s: 11: "orientation";i: 0; 
}

}

通过执行PHP文件，我想看到的结果：

Clipboard0340-100x65.jpg 
Clipboard0340-150x150.jpg 
Clipboard0340-198x143.jpg 
Clipboard0340-210x210.jpg 
Clipboard0340-300x209.jpg 
Clipboard0340-326x159.jpg 
Clipboard0340-326x235.jpg 
Clipboard0340-326x406.jpg 
Clipboard0340-513x357.jpg 
Clipboard0340-674x357.jpg

只需使用$ arr = json_decode（$ str） – 2015-03-30 19:41:08

有看看this页面。您需要使用循环（foreach或while）来遍历所有结果，然后使用echo将检索到的数据存储到数组中，然后将其打印出来。

希望有所帮助。
