So entfernen Sie den Array -Index von JSON in PHP
<?php
// numeric array keys with no gaps
$a = ['a', 'b', 'c'];
echo json_encode($a);
// ["a","b","c"]
// filter out the 'b' element to introduce a gap in the keys
$a = array_filter($a, function ($v) {
return $v !== 'b';
});
echo json_encode($a);
// {"0":"a","2":"c"}
// re-index the array to remove gaps
$a = array_values($a);
echo json_encode($a);
// ["a","c"]
