Ways to generate and get JSON files in PHP _php tips

The example in this article describes how PHP generates and obtains JSON files. Share to everyone for your reference, specific as follows:

First defines an array, then traverses the data table, puts the corresponding data into the array, and finally transforms the array by Json_encode ()

The function of the Json_encode () function is to convert a numeric value into a JSON data storage format.

putjson.php:

<?php
//Generate a PHP array
$data = Array ();
$data [0] = array (' 1 ', ' Wu-ran ', ' onestopweb.cn ');
$data [1] = Array (' 2 ', ' How to open ', ' iteye.com ');
Turn the PHP array into a JSON string
$json _string = Json_encode ($data);
Write file
file_put_contents (' Test.json ', $json _string);
? >

A JSON file with the same name is overwritten and not created.

The JSON that is generated or overwritten is as follows:

Copy Code code as follows:

[["1", "\u811a\u672c\u4e4b\u5bb6", "Www.jb51.net"],["2", "\u7f16\u7a0b\u5f00\u53d1", "jb51.net"]]

The data in the JSON file is then read into the PHP variable.

getjson.php:

<?php
//Read data from file to PHP variable
$json _string = file_get_contents (' Test.json ');
Turn the JSON string into a php array
$data = Json_decode ($json _string, true);
Show it to see
var_dump ($data);
Echo ' <br><br> ';
Print_r ($data);
Echo ' <br><br> ';
Echo ' number: '. $data [0][0]. ' Name: '. $data [0][1]. ' URL: '. $data [0][2];
Echo ' <br> ';
Echo ' number: '. $data [1][0]. ' Name: '. $data [1][1]. ' URL: '. $data [1][2];
? >
