Python Parse Json

How to Perform Decoding JSON in PHP?

In all honesty, the procedure of performing decoding JSON in PHP is quite easy and simple. However, still, if you are not careful enough, then you can end up writing incorrect codes. This, in turn, can make the whole process go wrong. Thus, to help you out in this aspect, here, we are going to provide you with some exclusive tips and examples. So, be sure to check them out!

The Parameters of Decoding JSON in PHP

If you have been decoding for quite some time, then you probably do already know about the parameters of decoding parse JSON android. Nonetheless, we would still proffer some insights of the same if someone new is going to work on it.

  • Json_string: It is a specific UTF-8 encoded string, which consists of a broad category of encoded data.
  • Options: An integer JSON bitmask, the options component supports the code – JSON_BIGINT_AS_STRING.
  • Depth: Like options, depth, too, is an integer parameter that specifies the recursion depth of something, i.e. a code.
  • Assoc: It is, in essence, a Boolean parameter, which helps in converting returning objects into associative arrays.

Examples of Performing Decoding JSON in PHP

So, here are some examples, which can help you to learn more about the parse JSON file python.

Example: 1

The first example depicts a situation where a specific JSON data has been assigned with a variable. Now, in this case, you are going to decode it by using the “json_decode ()” method. This way, it will be easier for you to read everything that is available in it by using PHP.

The code, which you are going to decode for this aspect, is –

<?php
// Store JSON data in a PHP variable
$persons = ‘{“John”:35,”Peter”:40,”Mac”:28,”Lisa”:20}’;
var_dump(json_decode($persons));
?>

After jotting it down, you will be able to see the array values and keys along with the type of data. Here, the age of a person will be set in numeric. Thus, the type of data can be seen in the end result as well.

Example: 2

In the second example, we are going to decode marks data alongside roll numbers, which has been generated in JSON formatting. In this case, you will need to use the voluntary parameter of the json_encode approach. Otherwise, you will not be able to view the overall number of elements available in it. Let’s check it.

<?php
// Store JSON data in a PHP variable
$marks = ‘{“1001″:95,”1002″:80,”1003″:78,”1004”:90, “1005”:83,”1006″:92}’;
var_dump(json_decode($marks,true));
?>   

Here, the output will offer an array object that comes with six different elements.

As you can see in the examples, the task of decoding JSON data in PHP requires a little bit of technical know-how about almost everything. In this case, then you will need to learn about different types of formatting first. Moreover, you will also require a decent amount of knowledge about the parameters. Otherwise, you might end up doing everything wrongly and ultimately failing in your project.
