In PHP, arrays and objects are two different data types. An array is an ordered collection of data, while an object is an instance, which has its own properties and methods. However, during development, we may need to convert an array into an object. This article will introduce how to convert a PHP array into an object.
PHP Array
In PHP, arrays can come in many forms, including indexed arrays, associative arrays, and multidimensional arrays. The following is a simple associative array:
$array = [ 'name' => 'Tom', 'age' => 20, 'gender' => 'male' ];
Convert an array into an object
You can easily convert a PHP array into an object using the PHP built-in function json_decode(). The specific steps are as follows:
- Use
json_encode()function to convert the array into JSON format:
$json = json_encode($array);
- Use
json_decode( )The function converts JSON format into an object:
$obj = json_decode($json);
At this time, $obj is an object, and its value can be obtained by accessing the properties of the object:
echo $obj->name; // 输出：Tom echo $obj->age; // 输出：20 echo $obj->gender; // 输出：male
Therefore, we can convert PHP arrays into objects through the above steps.
Note
- If the array contains complex data types, such as another array or object, the converted object will no longer be the data type in the PHP array.
- If the JSON contains special characters, such as slashes, quotation marks, carriage returns, etc., you need to use another parameter of the
json_encode()functionJSON_UNESCAPED_UNICODEto convert it Encoded as Unicode characters to avoid encoding errors.
Summary
Converting a PHP array into an object is easy, just use the PHP built-in function json_decode(). This function can create an object from a JSON-formatted string so that it has the properties of an object, including properties and methods. However, in practice, we need to pay attention to some considerations to avoid conversion errors.
