Php loop with json coming back empty - php

Question

what am i doing wrong here?
when i have only One result coming back this code works perfectly
$someObject = json_decode($data);
$id=$someObject->clips[0]->id;
but when i want to do a loop because i may get back 10 results this code is not working, i am sure i am missing something very simple here
$someObject = json_decode($data);
//var_dump($someObject);
foreach($someObject as $json){
echo $json->clips[0]->id;
}
EDIT:
this solution worked for anyone else who comes looking
foreach ($someObject->clips as $clip){
echo $clip->id. "<br>";
}
not sure how the other one answers the for loop issue i was having however.

Answer 1

You need to change this index [0] to dynamic index.
foreach($someObject as $k => $json){
echo $json->clips[$k]->id; // Insert $k here
}

Answer 2

change this
foreach($someObject as $json){
echo $json->clips[0]->id;
}
to
$i=0;
foreach($someObject as $json){
echo $json->clips[$i]->id;
$i++;
}
or as miken32 stated in the comment
foreach ($someObject->clips as $clip){
echo $clip->id;
}

Answer 3

read this reference: control-structures.foreach.php
in php array if you want to get all of items iterate you can use foreach
imaging you have this sample json:
{
"clips": [{
"id": 1,
"name": "test",
"tags": [
"tag1",
"tag2",
"tag3"
]
},
{
"id": 2,
"name": "test2",
"tags": [
"tag4",
"tag5",
"tag6"
]
}
]
}
if you want to get clips and tag list you can use this code:
<?php
$jsonText = '{"clips": [{"id": 1,"name": "test","tags": ["tag1","tag2","tag3"]},{"id": 2,"name": "test2","tags": ["tag4","tag5","tag6"]}]}';
$jsonObj = json_decode($jsonText);
// in this loop you can get clipObject
foreach($jsonObj->clips as $clipObj){
echo "clip id:" . $clipObj->id . "<br>\n";
echo "clip name:" . $clipObj->name. "<br>\n";
// in this loop you can get tags
foreach($clipObj->tags as $tag){
echo "clip tag:" . $tag. "<br>\n";
}
}
