Operating system for this tutorial: Windows 10 system, php8.1.3 version, Dell G3 computer.

In PHP, you can use the json_encode() function to convert an array into a JSON array.

The following is an example of coercing an array into a JSON array:

$array = array('apple', 'banana', 'orange');
jsonArray=jsonencode(jsonArray = json_encode(jsonArray=jsonencode(array);

In the above example, use the json_encode() function to convert the array array into a JSON format string and save the result to the jsonArray variable

Please note that the json_encode() function will convert the array to a JSON object instead of a JSON array by default. If you want to coerce an array into a JSON array, you can use the JSON_FORCE_OBJECT parameter or re-index the array index numerically.

Use JSON_FORCE_OBJECT parameter:

$array = array('apple', 'banana', 'orange');
jsonArray=jsonencode(jsonArray = json_encode(jsonArray=jsonencode(array, JSON_FORCE_OBJECT);

Use numeric index:

$array = array('apple', 'banana', 'orange');
array=arrayvalues(array = array_values(array=arrayvalues(array);  // 重新设置数组索引为数字索引
jsonArray=jsonencode(jsonArray = json_encode(jsonArray=jsonencode(array);

This will force the array to be converted to JSON array form.

Please note that when using the json_encode() function, ensure that the values ​​in the array comply with the JSON format requirements. For example, the string should be enclosed in double quotes.
