        }
        $content .= htmlspecialchars(print_r($vars, true));
        $content .= "\n

\ N ";
} Else {
$ Content = $ label. ": \ n". print_r ($ vars, true );
}
If ($ return) {return $ content ;}
Echo $ content;
Return null;
} Array_remove_empty () removes the empty element in the array. function array_remove_empty (& $ arr, $ trim = true ){
Foreach ($ arr as $ key => $ value ){
If (is_array ($ value )){
Array_remove_empty ($ arr [$ key]);
} Else {
$ Value = trim ($ value );
If ($ value = ''){

} Elseif ($ trim ){
$ Arr [$ key] = $ value;
}
}
