Remove Inline NULL values from PHP arrays

Remove NULL values from PHP arrays with 1 line (Inline)

I had an array with something like the following: Array ( [0] => [1] => test [2] => fun ). But I don’t want [0], the empty value in the array.

After searching the web for a good solution, I saw that people were using anywhere from 4 to 10+ lines of code to remove null values from arrays. This is obviously overkill so I decided to tackle the problem myself.

Remove NULL values only

1	$new_array_without_nulls = array_filter($array_with_nulls, 'strlen');

Remove any FALSE values

This includes NULL values, EMPTY arrays, etc. Thanks to Paul Scott for pointing out this method.

1	$new_array_without_nulls = array_filter($array_with_nulls);
