【问题描述】：

我想获取我的图像值，例如 images/thispicture.png。

我有一个带有一些值的数组或 Json，但问题是我只想要数组中的图像。

这是我现在从数组中得到的：

{"image_intro":"images\/16748007940_1cc8f06622_small.jpg","float_intro":"","image_intro_alt":"","image_intro_caption":"","image_fulltext":"","float_fulltext":"","image_fulltext_alt":"","image_fulltext_caption":""}"><img src="/{"image_intro":"","float_intro":"","image_intro_alt":"","image_intro_caption":"","image_fulltext":"","float_fulltext":"","image_fulltext_alt":"","image_fulltext_caption":""}"><img src="/{"image_intro":"","float_intro":"","image_intro_alt":"","image_intro_caption":"","image_fulltext":"","float_fulltext":"","image_fulltext_alt":"","image_fulltext_caption":""}

我只想要“image_intro”我该怎么做？

当我 json_decode 我得到这个输出：

["image_intro"]=>
  string(39) "images/16748007940_1cc8f06622_small.jpg"
  ["float_intro"]=>
  string(0) ""
  ["image_intro_alt"]=>
  string(0) ""
  ["image_intro_caption"]=>
  string(0) ""
  ["image_fulltext"]=>
  string(0) ""
  ["float_fulltext"]=>
  string(0) ""
  ["image_fulltext_alt"]=>
  string(0) ""
  ["image_fulltext_caption"]=>
  string(0) ""

怎么办？我怎样才能让它成为一个我可以回显的字符串？

提前致谢！

$array["image_intro"] ?
echo $yourArrayName["image_intro"];就够了。
