This article introduces you how to study JSON format, the content is very detailed, interested friends can refer to, I hope to help you.
After seeing such simple and interesting features, why not upgrade your PHP version to JSON format and try building your system using Ajax, and ditch the nasty and troublesome XML for our fast and concise JSON, you will be pleasantly surprised.
JSON is built on two structures:
A collection of name/value pairs. In different languages, it is understood as an object, record, struct, dictionary, hash table, keyed list, or associative array.
An ordered list of values. In most languages, it is understood as an array. Simply put, JSON actually takes advantage of some of the basic data structures most modern programming languages support, such as arrays, strings, objects, etc. A common data presentation format abstracted from the data. This enables the JSON data format to exchange data between programming languages that support these data structures.
Example of JSON format:
Use XML format to represent a student's name, student number, grades and other information, which may be as follows:
Zhang San 200801 80 Li Si 200802 90 The above XML is converted to JSON format: var StudentsJSON = { student:[ { name:'Zhang San', studentid:200801, grade:80 }, { name:'Li Si', studentid:200802, grade:90 } ] }
From the JSON format example above, we can see that XML and JSON have a good correspondence, and XML data can be easily converted to JSON. This is also true; most XML data can be converted to JSON without problems.
About how to carry out JSON format learning research to share here, I hope the above content can be of some help to everyone, you can learn more knowledge. If you think the article is good, you can share it so that more people can see it.
