Php echo json7/1/2023 ![]() ![]() "" // Output: Harry PotterĮcho $arr // Output: $20. Call the function and print all the valuesĮcho "". Decode JSON data into PHP associative array format "name": "Harry Potter and the Goblet of Fire", Assign JSON encoded string to a PHP variable Return array('total' => $count, 'values' => $values) Values true, false and null are returned as true, false and null respectively.null is returned if the json cannot be decoded or if the encoded data is deeper than the nesting limit. Return total count and values found in array Returns the value encoded in json in appropriate PHP type. Strings must be enclosed in double quotes " and can contain escape characters such as \n, \t and \. In JSON, keys are always strings, while the value can be a string, number, true or false, null or even an object or an array. Array: This is defined as an ordered list of values.Multiple key/value pairs are separated by a comma. Each object begins with a left curly bracket. Object: This is defined as a collection of key/value pairs (i.e.JSON, like XML, is a text-based format that's easy to write and easy to understand for both humans and computers, but unlike XML, JSON data structures occupy less bandwidth than their XML versions. JSON is a standard lightweight data-interchange format which is quick and easy to parse and generate. JSON stands for Java Script Object Notation. throw new Exception('mb_convert_encoding(\''.$string.'\',\'UTF-8\',\''.$originalEncoding.In this tutorial you will learn how to encode and decode JSON data in PHP. $string = mb_convert_encoding ( $string, 'UTF-8', $originalEncoding ) // $this->toUtf8($string) $originalEncoding = mb_detect_encoding ( $string ) If( $i query ( '/catalog/items/item' ) ĬonvertEncoding($chr, 'UTF-16BE', 'UTF-8') If you need to quote a string in xpath it's If you need to quote javascript/json strings its If you need to quote shell arguments, it's ![]() ![]() If you need to escape HTML, it's (unfortunately) In both cases, a backslash will be added after the apostrophe in "O'Reilly" only in the second case will the backslash be included in the string length as recorded by serialize().Īddslashes is *never* the right answer, it's (ab)use can lead to security exploits! Such a mismatch can occur if you serialize the result of addslashes() and store it in a database some databases (definitely including PostgreSQL) automagically strip backslashes from "special" chars in SELECT results, causing the returned string to be shorter than it was when it was serialized. serialize() stores strings with their length the length must match the stored string or unserialize() will fail.
