![]() The remainder are mostly specific options to customise the encoding used in particular scenarios. You can obtain the full list of flags within the PHP documentation. But this fails in the case when we want to receive JSON string as post data. It is known that all of the post data can be received in a PHP script using the POST global variable. By default, jsondecode() returns a generic PHP object. jsondecode () function: This function takes a JSON string and converts it into a PHP variable that may be an array or an object. By using jsondecode(), you will be able to access all the variables as object properties or array elements. PHP will try to substitute invalid values in order to produce some output, even if it’s not complete. This is where jsondecode() comes into play. ![]() 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. If you are escaping strings in javascript and want to decode them in PHP with urldecode (or want PHP to decode them automatically when you're putting them in the query string or post request), you should use the javascript function encodeURIComponent () instead of escape (). Setting it to true will return an associative array, and false will return objects. In a previous tutorial, I showed how to send JSON data via POST in PHP.This led to somebody asking me how to receive JSON POST data with PHP. The second parameter determines how the decoded data is returned. The first parameter specifies the string that you want to decode. 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. The jsondecode () function accepts four parameters, but you will only need the first two in most situations. ![]() 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. This handles the case where a variable contains an associative array which might be empty. JSON_FORCE_OBJECT – Convert PHP numerical arrays to JSON objects instead of arrays.
