How to call an object's method in an array using array_map?

In PHP version 5.3, methods of objects in array can be called using the below code −

$props = array_map(function($obj){ return $obj->getProp(); }, $objs);

This will be slower than using a "for" loop because it Call a function per element −

function map($obj) {
   return $obj->getProperty();
}
$props = array_map('map', $objs);

Alternatively, for versions prior to PHP 5.3, you can use the following code −

function map($obj) {
   return $obj-> getProperty ();
}
$props = array_map('map', $objs);
}

will call the getProperty function on all objects and display the specific property. Instead of −

function encode_data($val){
   if(is_array($val)){
      return $val = array_map('encode_data', $val);
   } else {
      return utf8_encode($val);
   } 
}
$value = array_map('encode_data', $value);
print_r($value);

the utf8 encoded data of this value will be displayed.
