#PHP JSON DECODE AS ARRAY HOW TO#
$arr = (array) $obj How to Convert object to array in PHP?Īs we all know, there are several formats of data like strings, objects, arrays etc. In the case of PHP also, there are data formats like this.
In order to get the needed output, a php object obj result is needed in a format of an associative array. Now, let us see how to translate a php object. In order to encode the string, use “object = json_encode($array) ”.This is the skeleton for converting an object into an array. When the object is var_dump, all items will be displayed after converting into an array.It will be done using $obj = json_decode(json_encode($arr)) For decoding into an object, a json string which is available will be used to convert and string formatting is done to an object.When the object is var_dump, all items will be displayed. Here, one important point to consider is json_decode that translates a json string to an object, except you offer another option that is boolean which can be true or false. Even if the second parameter is considered as true, an array will be obtained.Īlso, when json encode operation and decode operation are used, arrays are converted to objects that take up many resources if the array is large. In that case, the better method to type cast an array to an object that uses the object cast.Ĭonsider $obj = (object) $arr syntax. Here also, object will be converted into arrays.īased on the requirements, you can choose the method you want for the conversion of an array into an object in PHP.ĭifferent examples are mentioned below: Example #1 PHP program to convert an object to an array using the typecasting method. In this program, a class hospital is created, and inside that, three elements such as el1, el2, and el3. Then, a _construct() function is declared, which gets executed during the time object is created.

Once this is done, the constructor takes parameters that are later offered during the object creation using the keyword “new”. But in the second case of expression, an object is casted into an array using the typecasting procedure.įrom the program, it can be seen that objects get printed in the first case of expression var_dump(). $arr = json_decode(json_encode($dis), true) PHP program to convert an object to an array using json encode and json decode. In this PHP Tutorial, we learned how to parse a JSON string, using json_decode() function.In this program also, a class hospital is created, and inside that, two elements such as el1 and el2, are created. And then we can use indexing technique to access the values for corresponding keys. We can directly decode the JSON string into an associative array by passing true for the second argument. We shall display the object returned by json_decode() in the output.Īfter decoding into PHP object, we can access the values using keys as shown in the following program.
In this example, we will take a JSON string and parse it using json_decode() function with the default optional parameters. The other two parameters are used only in some special scenarios. Generally, the first two parameters are sufficient in most use cases while parsing a JSON string. Bitmask: JSON_BIGINT_AS_STRING, JSON_INVALID_UTF8_IGNORE, JSON_INVALID_UTF8_SUBSTITUTE, JSON_OBJECT_AS_ARRAY, JSON_THROW_ON_ERROR
If false (default value), an object is returned. If true, the returned object will be converted into an associate array. The syntax of json_decode() function is json_decode(string, associative, depth, flags)
