Getting out the value of a key in multidimentional array in php - php

Question

In my php query I got this output:
{"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}}]}]}
after using 'json_decode' method on it, I get this:
"(

In my PHP, how can I release the "name" object value (the result should be 'myprojectname') from this array? I've tried many foreach loops that got me nowhere.
Thank you,

Answer 1

It looks like you have one object, that when decoded actually only has one array item. So, in your case, ‘myprojectname’ may simply be “$projects[0][‘name’]”
If many array items, you could
foreach ($projects as $project) {
echo $project[‘name’];
}
EDIT: I took object provided and json_decoded it myself, it doesn't match the json_decoded item presented by OP -- the first image shows the code to var_dump 'name' OP desired, part of the code also below:
$decoded = json_decode($obj);
$projects = $decoded->projects;
$name = $projects[0]->name;

Answer 2

Your 'projects' contains an array ("projects":[{"id":127, ... }]). I assume that the 'projects'-array might contain multiple 'project'-objects like this?
{
"projects":
[
{
"id":127,
"name":"my-project"
},
{
"id":128,
"name":"my-other-project"
}
]
}
In that case you need the arrow notation to access the name property, for example:
foreach ($projects as $project_object) {
foreach ($project_object as $project) {
echo $project->name . '<br/>';
}
}
EDIT:
I took a minimal code example of the OP and got the expected result:
Can you add more details in your code snippets in your original question or provide us with a working example of your code?
There are some online PHP sandboxes that can help you with this. For example: I stripped out all code that does not seem related to your question and got the result you are looking for in two different ways:

It is also a good idea to sum up all the foreach loops that you already tried, so we can see if you were nearly there with your own solution. This way we can understand your question better and it prevents us from offering solutions that you already used.
