Question

I have a json array storred in a file looking like:

["bla bla","bla bla2","bla bla3"]

And if I want to remove one of these objects from the json array with the code below the json converts to another type of array looking like:

{"1":"bla bla","2":"bla bla2","3":"bla bla3"} 

I dont want this to happen because it screws up code in another place. How can I achieve this?

$eng = json_decode($en_banners, false);

unset($eng[$id]);

$myFile = "languages/banners.php";
$fh = fopen($myFile, 'w') or die("can't open file");
$stringData = "<?php \$de_banners='".json_encode($eng)

Answer 1

JavaScript arrays are zero-based so there’s no possible way to create a JavaScript array from a PHP array with gaps unless you fill the gaps:

$en_banners = '["bla bla","bla bla2","bla bla3"]';
$eng = json_decode($en_banners, false);
var_dump($eng);
$id = 0;
$eng[$id] = null; // Rather than: unset($eng[$id]);
var_dump(json_encode($eng));

If array keys are not relevant, you can simply ignore them:

$en_banners = '["bla bla","bla bla2","bla bla3"]';
$eng = json_decode($en_banners, false);
var_dump($eng);
$id = 0;
unset($eng[$id]);
var_dump(json_encode(array_values($eng)));

If none of these solutions apply, we need more data 🙂
