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

Use this code:

$source = array(
    array('a', 'b', 'c', 'd'),
    array('d', '_', 'b', 'a'),
    array('a', 'b', '_', '_'),
    array('d', 'c', 'b', 'a'),
    array('_', 'b', 'c', 'd'),
    array('d', 'c', 'b', 'a'),
);

$sourceCount = count($source);

for($i=0; $i<$sourceCount; $i++)
{
  if(in_array("_", $source[$i])) unset($source[$i]);
}
