How to convert data in PHP and applet into array

This article will introduce how to convert data in PHP and small programs into arrays, and implement data formatting.

1. Convert PHP to Array

If you use PHP to develop, it is also very convenient to convert data into an array. We can quickly achieve this through the json_decode function.

The json_decode function can convert JSON format strings into PHP objects or arrays. The specific usage is as follows:

$source = '{"name":"mike","sex":"male"}';
$array = json_decode($source,true);

Among them, $source is a JSON string, $array is the converted array, and the true parameter represents conversion to an associative array.

If your data is not a JSON string, you can use the explode function to split it into an array:

$source = "1,2,3,4,5";
$array = explode(',', $source);

Among them, $array is the split array, using "," as separator.

2. Mini program to array

The data in the mini program is usually in JSON format. We can use the JSON.parse() function to convert it into an object or array.

The specific usage is as follows:

var source = '{"name":"mike","sex":"male"}';
var array = JSON.parse(source);

Among them, source is a JSON string, and array is the converted object or array.

If your data is not a JSON string, then you can use the split function to split it into an array:

var source = "1,2,3,4,5";
var array = source.split(',');

Among them, array is the split array, use "," as separator.

3. Data formatting

After converting the data into an array, we need to format it for subsequent use.

For example, in PHP, we can use a foreach loop to traverse an array and process the data in the array:

foreach ($array as $key => $value) {
    // 处理代码
}

In a small program, we can use a for loop to traverse the array , and process the data in the array:

for (var i = 0; i <p>When formatting data, it can be processed according to specific needs. For example, we can recombine the data or format the date into the required format, etc. This part needs to be handled according to the actual situation. </p><p>Summary: </p><p>After converting the data into an array, we can use related functions in PHP or small programs to format it. In actual development, leaving some time to format the data can save the time and cost of subsequent operations and improve the readability and maintainability of the code. </p>
