You can use array_filter to remove empty value (null, false,'',0):
ReplyDeletearray_filter($array);
If you don't want to remove 0 from your array, see @Sabari's answer:
array_filter($array,'strlen');
You can use:
ReplyDeleteTo Remove NULL values only:
$new_array_without_nulls = array_filter($array_with_nulls, 'strlen');
To Remove False Values:
$new_array_without_nulls = array_filter($array_with_nulls);
Hope this helps :)
array_filter($array, function($var) {
ReplyDelete//because you didn't define what is the empty value, I leave it to you
return !is_empty($var);
});
That's a typical case for array_filter. You first need to define a function that returns TRUE if the value should be preserved and FALSE if it should be removed:
ReplyDeletefunction preserve($value)
{
if ($value === 0) return TRUE;
return FALSE;
}
$array = array_filter($array, 'preserve');
You then specify in the callback function (here preserve) what is empty and what not. You have not written in your question specifically, so you need to do it on your own.
