It is here to handle the broad basics of decoding JSON in PHP and accessing the results. Using the mb_str_split function is recommended, because mb_str_split correctly splits a string accounting for multi-byte characters as well. This is intended to be a general reference question and answer covering many of the never-ending 'How do I access data in my JSON' questions. Note that the use of str_split function to split a string that needs to be split into characters (as opposed to bytes) is incorrect, because str_split function only splits a string on a given number of bytes, even if a character takes multiple bytes to represent. This is a breaking change because the output of str_split function is different since PHP 8.2. Mb_str_split from the Mbstring extension already behaves the way str_split does in PHP 8.2, returning an empty array for empty string inputs. $length, the second parameter of str_split function, does not affect the return value for empty strings. Since PHP 8.2, calling str_split on an empty string returns an empty array: str_split('') = Please note that you will receive an email notification when new reply is posted. This change can be a breaking change for applications that relied on this erroneous behavior in the implementations in older PHP versions. I have seen datatables solutions but that dint get my design results. This is now fixed in PHP 8.2 to correctly return an empty array ( ). This behavior is undocumented, and is unexpected because an empty string contains no bytes into which the string is split. Prior to PHP 8.2, the str_split function incorrectly returned an array containing an empty string ( "") when an empty string is split. Mbstring extension provides a counter-part named mb_str_split, that can correctly split a string into an array, containing a set number of characters, accounting for multi-byte characters. It might force me to go PHP 7+ only and direct old PHP version uses to some old version of our libraries.Str_split function splits a given string into an array, with each value containing a given number of bytes. I really don't want to fork our code to support PHP 5.4 (you'd be gobsmacked at how many are still using it - even 5.3 in some cases) and putting attributes in front of every function is just as horrible. Oof! But (.) the PHP 8.1 compatibility notes show an example without a return type. PHP explodes splits string by a given string and returns an array. But the return type doesn't work prior to PHP 7. Basically, it seems that you either need to specify a return type on a function / method or use that new attribute. One with the value 1 and one with the value 3. Therefore the array will have two fields. Regarding # - oh my, that could be a massive headache! I actually don't fully understand it yet, but this SO post helps a bit. In your example the single values are 1 and 3 (exploded from 1,3). Good to hear it have been relatively painless. Asking for help, clarification, or responding to other answers. We missed that one since we don't have anything that passes null in there. The following example uses the explode() function to convert a string of fruits separated by ', 'to an array of fruits. Thanks for contributing an answer to Stack Overflow Please be sure to answer the question.Provide details and share your research But avoid. I want to get the total numbers of digits in a integer, and then explode the integer: rxfreq 1331000000 ( 10 ) array 0 1 array 1 3.
