How to get array value by key

Question

I am having an strange issue while transversing array, created by html input. Here is my html:

<input type="hidden" name="new_date['rule'][]" value="hfgfgfgfg">
<input type="date" name="new_date['date'][]" />

if I submit form then I get array like this:

$var=$_POST['new_date'];
echo"<pre>";
print_r($var);
echo"</pre>";
//output
Array
(
    ['rule'] => Array
        (
            [0] => rule_5a6c50ff02fff
        )

    ['date'] => Array
        (
            [0] => 2018-05-24
        )

)

if I am trying the array with key rule then I am getting nothing or empty.

print_r($var['rule']);
//output
.....empty......

Please help. TIA

In HTML you have used new_date['rule'][] which have key as 'rule' so while retriving through POST you need to use same key i.e. with single quote

USE below:

var_dump($var["'rule'"])

To use : $var['rule'] you may need to use new_date[rule][] in your html

You can try this

<input type="hidden" name="new_date[rule][]" value="hfgfgfgfg">
<input type="date" name="new_date[date][]" />

This will work

echo $var["'rule'"][0];

This is because you are using

name="new_date['rule'][]"

in HTML. Instead you should use

name="new_date[rule][]"

Hopefully, this will solve your problem

If you var_dump() $var, this will be the output:

array(2) {
  ["'rule'"]=>
  array(1) {
    [0]=>
    string(9) "hfgfgfgfg"
  }
  ["'date'"]=>
  array(1) {
    [0]=>
    string(10) "2018-05-11"
  }
}
