JSON uses JavaScript syntax, learn more JSON Tutorial[^]
this

{"Rec": [{"SlNo":1,"Name": " ","DOB": " "}]}

represents a json array called "Rec" that contains one object element with these property-value pairs {"SlNo":1,"Name": " ","DOB": " "}.
One of the two ways to get the values of these property is through the object way. Learn PHP: Classes and Objects - Manual[^]

C#

<?php
$json = '{"Rec": [{"SlNo":1,"Name": " ","DOB": " "}]}';
// decode it to an object
$object = json_decode($json);
//var_dump($object);
// get its property "Rec" which is an array
$Rec = $object->Rec;
// get the first and only object element of $Rec property
$element = $Rec[0];
// get the property of "SlNo" from this object element
echo $element->SlNo;
?>

Any way is to through the associative array using

json_decode($json, true)

I will leave it to you to explore this option. Learn PHP 5 Arrays[^]
