The remainder are mostly specific options to customise the encoding used in particular scenarios. Now let us see simple example which uses jsondecode () of PHP in a HTML structure.

#Php json decode array of objects full#

You can obtain the full list of flags within the PHP documentation. This jsondecode () function of PHP takes JSON encoded string as input and returns the value that is decoded to PHP objects which of PHP data types and if the decoding is not possible then this function returns null instead of PHP objects. php -S localhost:8000 encode.php We start the server and locate to the localhost:8000. PHP will try to substitute invalid values in order to produce some output, even if it’s not complete. The example transforms a PHP array into a JSON string. JSON_PARTIAL_OUTPUT_ON_ERROR – Try to continue writing even after an encoding error is encountered.With this enabled, a PHP value '234.5' will be emitted as 234.5 in the JSON. JSON_NUMERIC_CHECK – Automatically converts numeric strings to numbers in the JSON output, instead of preserving them as strings.JSON_PRESERVE_ZERO_FRACTION – Forces PHP to encode floats such as 0.0 exactly, instead of shaving off the fraction to write 0 into the JSON (which could be incorrectly parsed as an integer).

Setting this flag will add new line characters and automatic indentation to the JSON string, making it more suitable for configuration files and other scenarios where humans will read the output. // init.php containing your PDO definition, along the line of: // dbObj new PDO ('mysql:host dbname', '', '') require 'init.php' include 'config.

JSON_PRETTY_PRINT – PHP’s JSON output is normally minified which is ideal when sending it over the network as part of an HTTP request.Enabling this flag ensures an object is always used in the encoded JSON. When the array is empty ( ), a JSON array would be created when it’s not empty ( ), an object would be emitted instead. If the JSON failed to be decoded or the JSON is deeper than given depth then null gets returned. When true, false, or null is passed for JSON, the function returns same true, false, or null respectively. This handles the case where a variable contains an associative array which might be empty. The jsondecode () function decodes the JSON string to appropriate PHP type based on the parameter. In JSON, array values must be of type string, number, object, array, boolean or null. PHP jsondecode () This native PHP function decodes the JSON string into a parsable object tree or an array.

JSON_FORCE_OBJECT – Convert PHP numerical arrays to JSON objects instead of arrays. Arrays in JSON are almost the same as arrays in JavaScript.
