How to echo special value from key in array/json structure - php

Question

I can easly explore json for example:
foreach($json_a['somwhere'][1]['somwhere_deeper'] as $something){
var_dump($something);
}
This code makes me print something like this:
C:\wamp64\www\dothejob.php:7:
array (size=2)
'name' => string 'John' (length=17)
'value' => string '15' (length=4)
C:\wamp64\www\dothejob.php:7:
array (size=2)
'name' => string 'Joanna' (length=6)
'value' => string '23' (length=2)
C:\wamp64\www\dothejob.php:7:
array (size=2)
'name' => string 'John' (length=17)
'value' => string '55' (length=10)
C:\wamp64\www\dothejob.php:7:
array (size=2)
'name' => string 'Joanna' (length=11)
'value' => string '55' (length=5)
So I'm sure I'm in a right place, but now the question is how to print only value which is in array, where name is Joanna?
I know it should be easy If statement, but I'm not sure how those keys/values works, Its easy question, but I'm beginner with php... :) ps. I was looking for help but didn't found solution yet.
Can't use $something[n], because they are not allways on the same "place", so only right solution is something like this:
I'm looking for something like this:
if 'name' is 'Joanna':
print value of 'value'

Answer 1

You can use $something[n] because you have an associative array :
foreach($json_a['somwhere'][1]['somwhere_deeper'] as $something){
if ($something['name'] == 'Joanna') {
var_dump($something);
}
}
Output should be :
C:\wamp64\www\dothejob.php:7:
array (size=2)
'name' => string 'Joanna' (length=6)
'value' => string '23' (length=2)
C:\wamp64\www\dothejob.php:7:
array (size=2)
'name' => string 'Joanna' (length=11)
'value' => string '55' (length=5)
Of course, if you want to var_dump the value only, use var_dump($something['value']).

Answer 2

you need to update naming convension of Variable
foreach($json_a['somwhere'][1]['somwhere_deeper'] as $key => $value){
echo $key." : ".$value
}
Output of above code will be something like
John : 15
Johnna : 23
foreach(array as key => value)
{
//key represent array key
//value represent value of that array
}
Let me know in case of any concern.
