I've got a problem.
I have got this array:
Array (
[0] => Array (
[id] => 1
[opt] => reg_limit
[value] => 0
)
[1] => Array (
[id] => 3
[opt] => pages_offline
[value] => []
)
[2] => Array (
[id] => 4
[opt] => devolp
[value] => TRUE
)
)
I want to check if the [opt] devolp has the [value] TRUE in the third array. How can I do?

Answer 1

$aArray = Array (
[0] => Array (
[id] => 1
[opt] => reg_limit
[value] => 0
)
[1] => Array (
[id] => 3
[opt] => pages_offline
[value] => []
)
[2] => Array (
[id] => 4
[opt] => devolp
[value] => TRUE
)
)
foreach($aArray AS $aInnerArray){
if($aInnerArray['opt'] == 'devolp' && $aInnerArray['value'] == TRUE){
//YOUR USE CASE
}
}

Answer 2

if ($array[2]['value']) echo 'true';

Answer 3

Since the OP's question is quite vague on the details wether or not he knows which array key he needs to check,
Here is a simple example that you can use if you know the array key that you need to check in.
$bool = $yourMultiDeminsionalArray[2]['value'];
if ($bool) {
//Do some awesome PHP shizzle here
}

Answer 4

Provided you will work with a big array in the future and need some flexibility, this foreach will work for you:
foreach($array as $a) {
if(array_key_exists("opt", $a) && $a['opt'] == "devolp") {
if(array_key_exists("value", $a) && $a['value'] == TRUE) {
echo "Found it!";
//Do whatever you need to do here....
}
}
}
