PHP Array of arrays of arrays - php

Question

I am trying to search this array by the value of ['field'] and then return the value of ['value'] associated with that field in the array.
For example, I want to say "Tell me the value associated with theThirdField".
I've tried many, many permutations of something like the following:
$myVariable = $Array['result']['totalrows'][0]['rownum'][0]['field'];
To further clarify, I will never know which order / sub-array my search field is located in, I only know the string value associated with ['field'].
How would I accomplish this?
Array
(
[result] => Array
(
[totalrows] => 1
[rows] => Array
(
[0] => Array
(
[rownum] => 1
[values] => Array
(
[0] => Array
(
[field] => testMeOnce
[value] => 436586498
)
[1] => Array
(
[field] => testMeTwice
[value] => 327698034
)
[2] => Array
(
[field] => theThirdField
[value] => 108760374
)
[3] => Array
(
[field] => theFourthField
[value] => 2458505
)
[4] => Array
(
[field] => fifthField
[value] => -0.0201
)
)
)
)
)
)

Answer 1

Did you expect something like that?
$needle = 'theThirdField'; // searched field name
$valuesArray = $Array['result']['rows'][0]['values']; //now you have clearer array
array_walk($valuesArray, function($element, $key) use ($needle) {
if ($element['field'] == $needle) {
echo $element['value'];
}
});

Answer 2

I would do something like this, assuming you want to search only in the $myVariable dimension :
$myVariable = $Array['result']['rows'][0]['values'];
foreach ($myVariable as $key => $value) {
if( $value['field'] === 'theThirdField' ) {
echo $value['value'];
break;
}
}

Answer 3

when I ran your code, I got some syntax errors. I have changed your Array to this (changed syntax only):
$a = Array
(
'result' =>
[
'totalrows' => 1,
'rows' =>
[
0 =>
[
'rownum' => 1,
'values' =>
[
0 =>
[
'field' => 'testMeOnce',
'value' => 436586498
],
1 =>
[
'field' => 'testMeTwice',
'value' => 327698034
],
2 =>
[
'field' => 'theThirdField',
'value' => 108760374
],
3 =>
[
'field' => 'theFourthField',
'value' => 2458505
],
4 =>
[
'field' => 'fifthField',
'value' => -0.0201
]
]
]
]
]
);
now you can get the value like this:
print($a['result']['rows'][0]['values'][2]['value']); // --> 108760374
I hope that this is what you are looking for!

Answer 4

Thanks everyone. I used a mix of your suggestions and ended up doing the following:
$valuesArray = $Array['result']['rows'][0]['values'];
foreach ($valuesArray as $value) {
$fieldName = $value['field'];
$$fieldName = $value['value'];
}
Since I know the names of all the fields I want, but not the order, this allowed me to capture all of the values of each field with the name of the field becoming the variable name.
