PHP Array to JSON Array using json encode

Question

I ve encoded an Array I ve made using the inbuilt json encode    function  I need it in the format of an Array of Arrays like so      Afghanistan  32 12    Albania  32 12     However  it is returning as     2    Afghanistan  32 12   4    Albania  32 12     How can I remove these row numbers without using any Regex trickery

If the array keys in your PHP array are not consecutive numbers, json_encode() must make the other construct an object since JavaScript arrays are always consecutively numerically indexed.

Use array_values() on the outer structure in PHP to discard the original array keys and replace them with zero-based consecutive numbering:

Example:

// Non-consecutive 3number keys are OK for PHP
// but not for a JavaScript array
$array = array(
  2 => array("Afghanistan", 32, 13),
  4 => array("Albania", 32, 12)
);

// array_values() removes the original keys and replaces
// with plain consecutive numbers
$out = array_values($array);
json_encode($out);
// [["Afghanistan", 32, 13], ["Albania", 32, 12]]

If you don t specify indexes on your initial array  you get the regular numric ones   Arrays must have some form of unique index

I want to add to Michael Berkowski s answer that this can also happen if the array s order is reversed  in which case it s a bit trickier to observe the issue  because in the json object  the order will be ordered ascending   For example         3   gt   a       2   gt   b       1   gt   c       0   gt   d      Will return         0   d       1   c       2   b       3   a      So the solution in this case  is to use array reverse before encoding it to json

A common use of JSON is to read data from a web server  and display the data in a web page   This chapter will teach you how to exchange JSON data between the client and a PHP server   PHP has some built-in functions to handle JSON   Objects in PHP can be converted into JSON by using the PHP function json encode      x000D   x000D   lt  php x000D   myObj- gt name    John   x000D   myObj- gt age   30  x000D   myObj- gt city    New York   x000D   x000D   myJSON   json encode  myObj   x000D   x000D  echo  myJSON  x000D    gt  x000D   x000D   x000D

I had a problem with accented characters when converting a PHP array to JSON  I put UTF-8 stuff all over the place but nothing solved my problem until I added this piece of code in my PHP while loop where I was pushing the array   es words     array utf8 encode  quot  word quot    quot  alpha quot   quot  audio quot     It was only the   word  variable that was giving a problem  Afterwards it did a jason encode no problem  Hope that helps

json encode   function will help you to encode array to JSON in php    if you will use just json encode function directly without any specific option  it will return an array  Like mention above question   array   array    2   gt  array  Afghanistan  32 13     4   gt  array  Albania  32 12      out   array values  array   json encode  out         Afghanistan  32 13    Albania  32 12     Since you are trying to convert Array to JSON  Then I would suggest to use JSON FORCE OBJECT as additional option parameters  in json encode  Like below   lt  php  array   apple   orange   banana   strawberry    echo json encode  array  JSON FORCE OBJECT        0   apple   1   orange   2   banana   3   strawberry      gt
