HOW TO REMOVE EMPTY ELEMENT OR NULL VALUES FROM PHP ARRAY?

Okay let say that we have the following array

PHP

1	$arr = Array ( [0] => ‘php’ [1] => ‘tutorial’ [2] => ‘programming’ [3] => );

In our array above we have an empty element which is [3], so how to get rid of it? will that’s not a problem I will explain it here.

After searching and digging on the net I found 4 to 10 lines of code but I believed that there should be a simple possible solution for this, then I tried searching over php.net site and I found this very useful php array function array_filter().

To remove NULL values

PHP

1	$arr = array_filter($arr, ‘strlen’);

To remove all false values

PHP

1	$arr = array_filter($arr);

That’s it and it works like a charm;)
