Remove lines with empty values from multidimensional-array in php

Question

How do you remove the lines that have empty elements from a multidimensional-array in PHP?

For instance, from:

1: a, b, c, d
2: d, _, b, a
3: a, b, _, _
         


        

Answer 1

Try this:

Note: $arr is your array.

foreach ( $arr as $key => $line ) {

    foreach ( $line as $item ) {

        if ( empty( $item ) ) {

            unset( $arr[$key] );
            break;
        }

    }

}
