This function removes "blank" (null) elements from the array provided.
<?php
function clear_array ( $a ) {
if ( $a !== array() ) {
$b = array();
foreach ( $a as $key => $value ) {
if ( is_array ( $value ) ) {
if ( limpiar ( $value ) !== false ) {
$b[$key] = clear_array ( $value );
}
} elseif ( $value !== '' ) {
$b[$key] = $value;
}
}
if ( $b !== array() ) {
return $b;
} else {
return false;
}
} else {
return false;
}
}
?>
for example, some array as this:
<?php
$a = array (
"sihay" => 'valor',
"tambien" => 'otrovalor',
"subarray" => array (
"cosa" => 'aqui',
"nada" => ''),
"otrosub" => array() );
?>
using
<?php
$b = clear_array ( $a );
?>
will be converted into:
<?php
$b == array (
"sihay" => 'valor',
"tambien" => 'otrovalor',
"subarray" => array (
"cosa" => 'aqui') );
?>
