 Re: Cleans Array of Empty Records
Cleans Array of Empty Records
Here is the function that cleans array of empty records. It goes recursive through multidimensional array and erases any item that has empty value or is empty array.
This actually works on any variable type, not just arrays.
function clean_item ($p_value)
{
if (is_array ($p_value))
{
if ( count ($p_value) == 0)
{
$p_value = null;
} else
{
foreach ($p_value as $m_key => $m_value)
{
$p_value[$m_key] = clean_item ($m_value);
if (empty ($p_value[$m_key])) unset ($p_value[$m_key]);
}
}
} else
{
if (empty ($p_value))
{
$p_value = null;
}
}
return $p_value;
}
$m_array['aaa'] = 'bbb';
$m_array['ccc'] = '';
$m_array['ddd'] = Array();
$m_array['eee']['fff'] = Array();
$m_array['eee']['ggg'] = '';
$m_array['eee']['hhh'] = 'iii';
$m_array['eee']['j']['a'] = 'gh';
$m_array['eee']['j']['b'] = '';
$m_array['eee']['j']['c'] = 'rty';
$m_array['eee']['j']['d'] = Array();
$m_array['eee']['j']['e'][1] = 'r';
$m_array['eee']['j']['e'][2] = 'y';
$m_array['eee']['j']['e'][1] = '';
$m_array['eee']['j']['e'][4] = Array();
$m_array['eee']['j']['e'][5] = '';
$m_clean = clean_item ($m_array);
print_r ($m_array);
echo "<br>";
print_r ($m_clean);
OutPut:
Variable $m_clean contains:
Array
(
[aaa] => bbb
[eee] => Array
(
[hhh] => iii
[j] => Array
(
[a] => gh
[c] => rty
[e] => Array
(
[2] => y
)
)
)
)
