在我的php查询中,我得到以下输出:
{"projects":[{"id":127,"name":"efrat","status":{"id":10,"name":"development","label":"development"},"description":"","enabled":true,"view_state":{"id":10,"name":"public","label":"public"},"access_level":{"id":90,"name":"administrator","label":"administrator"},"custom_fields":[{"id":1,"name":"Customer email","type":"email","default_value":"","possible_values":"","valid_regexp":"","length_min":0,"length_max":50,"access_level_r":{"id":10,"name":"viewer","label":"viewer"},"access_level_rw":{"id":10,"name":"viewer","label":"viewer"},"display_report":true,"display_update":true,"display_resolved":true,"display_closed":true,"require_report":false,"require_update":false,"require_resolved":false,"require_closed":false}],"versions":[],"categories":[{"id":93,"name":"Monitor","project":{"id":0,"name":null}},{"id":31,"name":"Proactive","project":{"id":0,"name":null}},{"id":30,"name":"Project","project":{"id":0,"name":null}},{"id":29,"name":"Support","project":{"id":0,"name":null}}]}]}
在使用'json_decode'方法后,我得到了: “(

在我的PHP中,如何从该数组释放“名称”对象值(结果应为“ myprojectname”)?我已经尝试了许多foreach循环,但都无济于事。
谢谢

似乎您有一个对象,解码时实际上只有一个数组项。因此,就您而言,“ myprojectname”可能只是“ $ projects [0] [‘name’]”
如果有很多数组项,您可以
foreach($ projects作为$ project){
echo $ project ['name'];
}
编辑:我将提供的对象自己进行json_decoded,它与OP所提供的json_decoded项不匹配-第一张图片显示了所需的var_dump'name'OP的代码,是OP的一部分下面的代码:
$ decoded = json_decode($ obj);
$ projects = $ decoded-> projects;
$ name = $ projects [0]-> name;

您的“项目”包含一个数组()
.call(xAxis)
.selectAll("text")
.attr("y", 0)
.attr("x", 25)
.attr("dy", ".35em")
.attr("font-family", "ibm-plex-sans")
.attr("transform", "rotate(90)");
)。我假设“项目”数组可能包含多个“项目”对象,像这样吗?
"projects":[{"id":127, ... }]
在这种情况下,您需要箭头符号来访问name属性,例如:
{
"projects":
[
{
"id":127,
"name":"my-project"
},
{
"id":128,
"name":"my-other-project"
}
]
}
编辑:
我以OP的最小代码示例为例,并得到了预期的结果:
您能否在原始问题的代码段中添加更多详细信息,或者向我们提供您的代码示例? 有一些在线PHP沙箱可以帮助您解决此问题。例如:我去除了所有与您的问题无关的代码,并以两种不同的方式获得了您正在寻找的结果: http://sandbox.onlinephpfunctions.com/code/009c53671fd9545e4fcecfe4b0328974381ee2ce
总结您已经尝试过的所有foreach循环也是一个好主意,因此我们可以查看您是否有自己的解决方案。这样,我们可以更好地理解您的问题,并且使我们无法提供您已经使用的解决方案。
