arrays - PHP Recursive Function, return error -


i create php function test if $var exist , not empty.

but, have problem can't identify :

  • in foreach, return false ignored because 'return' return first.

look : 

    function notempty($var, $r=false){     if(gettype($var)=='string' or gettype($var)=='integer'){         if($r==false){             if(isset($var) , @!empty($var)){                 return true;             }else{return false;}         }else{             if(!isset($var) , @empty($var)){                 return false;             }         }     }elseif(gettype($var)=='array'){         foreach($var $val){             if(gettype($val)=='array'){                 notempty($val, true);             }else{                 if(empty($val) or $val==''){echo "string";                     return false;                 }             }         }         return true;     }else{return null;} }

i call function : - notempty(array($val1, $val2, $val3));

i guess more or less looking for: 

<?php  function notempty($array, $recursive=false) {     $empty = array_filter($array, function($element) use ($recursive) {         if (is_array($element) && $recursive) {             return !notempty($element);         } else {             return empty($element);         }     });     return 0===count($empty); }  var_dump(notempty([1, 2, 3])); var_dump(notempty(['foo', '', 'bar'])); var_dump(notempty(['foo', null, 'bar'])); var_dump(notempty(['foo', [1,2,3], 'bar'])); var_dump(notempty(['foo', [1,null,3], 'bar'])); var_dump(notempty(['foo', [1,null,3], 'bar'], true));

the output of is: 

bool(true) bool(false) bool(false) bool(true) bool(true) bool(false)
