json_encode Array with int index

I need to encode a similar Array:

Array
(
    [0] => 393922111111
    [1] => 393433333333
    [2] => 393555555555
)

with json_encode.

I'm getting this:

["393922111111","393433333333","393555555555"]

that seems not correct. I.e. i put it into a

 echo '<input type="hidden" id="destinatariSMS" name="destinatariSMS" value="';
     echo json_encode($destinatariSMS);
 echo '" />'.PHP_EOL;

and in next page 'll receive only first bracket.

Could you gimme some hint? Thank you!

You do elementary mistake by not escaping your encoded json correctly prior putting is as INPUT value. Some characters, including " needs to be quoted (" => &quot;) to "work" with HTML. So valid code should be:

echo '<input type="hidden" id="destinatariSMS" name="destinatariSMS" value="';
echo htmlspecialchars(json_encode($destinatariSMS));
echo '" />'.PHP_EOL;

When you output to html, you should use htmlspecialchars to encode your output so that it cannot break the html:

 echo '<input type="hidden" id="destinatariSMS" name="destinatariSMS" value="';
     echo htmlspecialchars(json_encode($destinatariSMS));
 echo '" />'.PHP_EOL;

In your case the quotes in your json close the value attribute.
