Having: an array $a, a variable $indexes = "[\"level1\"][\"level2\"][\"level3\"]";
Is there any way to access $a["level1"]["level2"]["level3"]?
The situation is that the number of indexes that this function will handle can change. So this is the reason the indexes comes in a variable.
Hope this simple solution will help you out.
<?php
ini_set('display_errors', 1);
//Here we are retrieving levels
$indexes = '["level1"]["level2"]["level3"]';
preg_match_all('/(?<=")[\w]+(?=")/', $indexes,$matches);
$levels=$matches[0];
//this is the sample array
$array=$tempArray=array(
"level1"=>array(
"level2"=>array(
"level3"=>"someValue"
)
)
);
//here we are iterating over levels to get desired output.
foreach($levels as $level)
{
$tempArray=$tempArray[$level];
}
print_r($tempArray);
